Genetically-altered trees have been developed that can remove toxins from the air more quickly than naturally-occurring trees can. However, we will not know whether the modified trees adversely affect the environment without actually planting them and carefully monitoring the environment for at least several years. Since this might cause irrevocable harm to the surrounding area, we should resist the temptation to use these trees until long-term research in a closed environment has been completed.
Which of the following best describes the method of argument used in the argument above?

The course of action that is advised against is planting genetically-altered trees to remove toxins. The similar, but limited, course of action is long-term research involving the planting of such trees in a closed environment. Positive results from the limited action – no serious damage to the environment – need to be seen; otherwise, we should “resist the temptation” to plant the trees in the open.
"After detailing concerns with two approaches to a problem, both are discarded in favor of an approach that does not raise the same concerns." This choice mentions two approaches, and then “another approach,” making for three approaches in total. However, only two approaches are ever mentioned: planting them in the general environment, or planting them in a closed environment.
"A possible future scenario is described as being unrealistic, while a different scenario is given more credence." No particular scenario is ever described as unrealistic.
"An experiment is recommended to determine the benefits of a new approach to a longstanding problem for which no other comparable solution is known." This choice starts out fine, but we cannot say that “no other comparable solution is known.” If anything, we are told that naturally occurring trees can be used to remove toxins, though slowly.
"The benefits and disadvantages of two remedial courses of action are weighed." It is not clear that the argument presents two distinct remedies. Even if we consider planting the trees in an open environment to be one remedy and planting the trees in a closed environment to be another remedy, no disadvantages to planting the trees in a closed environment are mentioned. If we consider planting naturally-occurring trees to be a second approach, then this answer choice does not even mention long-term research.
The correct answer is "A course of action is advised against unless a similar, but limited, course of action produces positive results."

A large company has recently increased its dividend payments to shareholders. Shareholders had previously been worried about the company's stock price, but are now relieved since increasing dividends generally boosts a company's stock price. However, the shareholders' optimism may be ill-founded since spending money on the payment of dividends often indicates that the company has exhausted more lucrative investments for its cash reserves and that the stock price will likely fall in the longer run.
In the argument above, the two bold-faced portions play which of the following roles?

This Boldface problem rewards those who can adeptly deconstruct arguments and find conclusions. Here the main conclusion of the argument is "the shareholders' optimism may be ill-founded" - you know that this is a conclusion because it is adjacent to the word "since" (which gives a reason for the conclusion - remember, conclusions must pass the "why test" in which some other portion of the argument tries to explain why it is true). And you know that it's the main conclusion because it follows "however," a signal that the author has introduced an idea and then transitioned to her main point.
With this knowledge you're ready to attack the answer choices and pick apart the subtle difference between popular choices. The first bolded portion is evidence that is used to support a conclusion (just not the main conclusion) - it's a reason that some shareholders believe that they do not have be be worried about the company's stock price.
The second bolded portion is evidence for the main conclusion - it's the reason that the shareholders' optimism may be unfounded.When you attack the answer choices, note that "The first is evidence that supports a conclusion; the second is that conclusion." and "The first is a premise that is accepted as true; the second is a conclusion that is contrary to the premise." each clearly mischaracterize the second bolded portion as a conclusion when in fact it is a premise.
Among the other choices, recognize that the goal of the argument - as evidenced by the conclusion - is to show that the shareholders' optimism is misplaced, NOT to clarify the initial fact. Again, this goes back to isolating and fixating on the conclusion. This is why choice "The first describes evidence that supports a conclusion; the second gives a reason for questioning that support." is correct: it properly notes the role of the second bolded portion, to support the conclusion that the optimism is unfounded (which, conceptually, is the same thing as questioning the shareholders' logic). Choices "The first describes the circumstance that the argument seeks to explain; the second provides evidence in support of the explanation that the argument seeks to establish." and "The first is a premise that is accepted as true; the second seeks to clarify the original premise." are each tempting, but each suggests that the purpose of the argument is to clarify the fact in the first sentence, when in fact the conclusion is clear in its intention to question the logic of the shareholders.

Some analysts predict that next year will see total worldwide sea shipping tonnage increase by 2% over the current year. However, captains of freight ships generally expect that worldwide shipping tonnage will decrease next year. At issue is the amount of freight that will be shifted from sea ships to freight airplanes as compared to growth in the overall demand for freight transport. The analysts believe growth in demand will outstrip the shift to freight airplanes; the ship captains believe the opposite.

The question stem, “The two portions in boldface play which of the following roles?”, clearly indicates this is a “Roles in Boldface” question, a subtype of the Method category. In order to successfully answer this question, we must analyze the “big picture” of the argument, focusing on structure, not topic. The correct answer will describe the function of the two bolded statements within the argument. Stepping back to look at the entire argument independent of its contextual context provides an insight into what role each piece plays. In essence, the argument states: “Some people believe X. Other people believe Y. The reason they disagree is Z. Some people believe X; the other people believe Y.” Because “Roles in Boldface” questions often contain overlapping answers, these questions are susceptible to process-of-elimination techniques. By correctly categorizing one of the two bolded statements, we can often eliminate more than one answer choice. The second bolded statement (“The reason they disagree is Z”) is likely the easier one to evaluate because it is distinctly different from the rest.
Looking down at the answer choices, “The first portion is evidence that supports a position; the second portion is a position that is not necessarily true based on the evidence.” and “The first portion represents one of two opposed positions; the second portion represents the opposing position.” both call the second bolded statement “a position” of one of the two groups. “The first portion represents one of two opposed positions; the second portion is evidence in support of that position.” and “The first portion is evidence that supports a position; the second portion is evidence that supports an opposed position.” call it “evidence in support” of a position. Only “The first portion represents one of two opposed positions; the second portion describes the underlying reason for the difference in position.” correctly identifies the second portion as the underlying reason for why the two groups disagree. We can actually eliminate four of the five answers without needing to evaluate the first bolded statement. The answer must be “The first portion represents one of two opposed positions; the second portion describes the underlying reason for the difference in position.”.
Just to check ourselves, we can evaluate the first statement to see if it fits (“Some people believe X.”) The first statement is clearly a statement of one of two positions, so it matches perfectly with “The first portion represents one of two opposed positions; the second portion describes the underlying reason for the difference in position.”.

Recently, some economists have concluded that the major impediment to job growth in the U.S. is the enormous national debt. While many politicians would like to stimulate job growth by increasing government spending, these economists believe it will have the opposite effect and thus want to cut spending immediately. Historically, when total debt levels exceed 90% of domestic GDP, economic growth falls significantly causing job losses and overall economic malaise. The current U.S. debt is over 96% of GDP, so it is hard to argue the importance of decreasing this percentage and the economists are correct on this point. However, what these economists fail to understand is that cutting spending at this critical juncture would put too much pressure on a fragile economy. In the short term, spending should be left at current levels and revenue should be increased by increasing taxes on wealthy individuals and some corporations. As the economy strengthens, then spending can be decreased with the goal of reducing the debt percentage of GDP to a figure below 90%.

For any boldfaced question, it is essential that you first understand the complete argument. In this stimulus, it is stated that some economists believe that the enormous debt is the major impediment to job growth. As a result, these economists believe that spending should be cut immediately to reduce the debt. The evidence they give for their argument is that current debt levels are 96% of GDP and when total debt levels exceed 90% of domestic GDP, economic growth falls significantly causing job losses and overall economic malaise. The author of this argument agrees that reducing debt is essential but believes that an immediate reduction of spending would be problematic because the economy is too fragile. His recommendation and conclusion is that spending levels should be left constant in the short term and revenues increased with more taxes. Then, after the economy has recovered, spending should indeed be reduced. In summary, the author agrees with the economists that the major impediment to job growth is the high debt level but disagrees with their short term plan because the economists have not considered the fragile state of the economy. With that understanding of the argument, you must then attack each answer choice to see how the boldfaced sections are described:
"The first boldfaced portion is an opinion that the author of this argument believes is incorrect; the second boldfaced portion is support for that opinion." The author does not believe that first boldfaced portion is incorrect but rather believes it is correct. He disagrees with their assertion that “spending should be cut immediately” but agrees with this boldfaced portion. While the second boldface portion is described correctly, "The first boldfaced portion is an opinion that the author of this argument believes is incorrect; the second boldfaced portion is support for that opinion." is incorrect because of the description of the first boldfaced portion.
"The first boldfaced portion is an opinion that the author of this argument believes is incorrect; the second boldfaced portion is support for the author’s conclusion." This answer choice also incorrectly describes the first boldfaced portion. While the second does support the author’s conclusion, "The first boldfaced portion is an opinion that the author of this argument believes is incorrect; the second boldfaced portion is support for the author’s conclusion." contains the same error as "The first boldfaced portion is an opinion that the author of this argument believes is incorrect; the second boldfaced portion is support for that opinion." with the first boldfaced portion.
"The first boldfaced portion is an opinion that the author believes is correct; the second boldfaced portion is support for that opinion." The first boldfaced portion is an opinion that the author indeed believes is correct. The second boldfaced portion is the essential premise for that opinion so "The first boldfaced portion is an opinion that the author believes is correct; the second boldfaced portion is support for that opinion." is correct.
"The first boldfaced portion is an opinion upon which the author’s conclusion is based; the second boldfaced portion is evidence that contradicts that conclusion." In this choice, it is correct to say for the first boldfaced portion that the author’s conclusion is based on the opinion that the major impediment to job growth in the U.S. is the enormous national debt. However, the second boldfaced portion does not contradict the author’s conclusion but rather supports it so "The first boldfaced portion is an opinion upon which the author’s conclusion is based; the second boldfaced portion is evidence that contradicts that conclusion." is incorrect
"The first boldfaced portion is the author’s conclusion; the second boldfaced portion is support for that conclusion." The first boldfaced portion is not the author’s conclusion but rather the opinion of several other economists. The author’s conclusion is given in the last two sentences that are not boldfaced.

Recently, motorists have begun purchasing more and more fuel-efficient economy and hybrid cars that consume fewer gallons of gasoline per mile traveled. With that trend, there has been debate as to whether we can conclude that these purchases will actually lead to an overall reduction in the total consumption of gasoline across all motorists. The answer is no, since motorists with more fuel-efficient vehicles are likely to drive more total miles than they did before switching to a more fuel-efficient car, negating the gains from higher fuel-efficiency.
Which of the following best describes the roles of the portions in bold?

As you deconstruct the argument in this Boldface question, recognize first that the first bolded sentence is a premise, stated as a fact. Further, the beginning of the next sentence states "with that trend...," establishing that the argument will build from that fact. From here you can eliminate choices "The first states a position taken by the argument; the second introduces a conclusion that is refuted by additional evidence." and "The first is a conclusion that is later shown to be false; the second is the evidence by which that conclusion is proven false." (each of which says that the first portion is a conclusion). You can also be very skeptical of choice "The first is a premise that is later shown to be false; the second is a conclusion that is later shown to be false.": even though it correctly says that the first portion is a premise, note that it goes on to say that the argument proves that premise false. As you will see from the rest of the paragraph, the argument is concerned with attacking a conclusion drawn from that premise, but never tries to disprove the fact itself. For this reason, "The first is a premise that is later shown to be false; the second is a conclusion that is later shown to be false." is also incorrect.
As you look at the second bolded portion, note that the phrase "there has been debate as to whether we can conclude" is also direct cause for eliminating "The first is a premise that is later shown to be false; the second is a conclusion that is later shown to be false.": the second bolded portion is not the conclusion itself, but rather the introduction of the conclusion. You should see that this language matches choice "The first describes a premise that is accepted as true; the second introduces a conclusion that is opposed by the argument as a whole." perfectly, so choice "The first describes a premise that is accepted as true; the second introduces a conclusion that is opposed by the argument as a whole." is correct.
Similarly "The first is evidence that has been used to support a position that the argument as a whole opposes; the second provides information to undermine the force of that evidence." is incorrect, as the second bolded portion introduces a conclusion that could be drawn based on the first premise: it does not, as "The first is evidence that has been used to support a position that the argument as a whole opposes; the second provides information to undermine the force of that evidence." says "undermine that evidence." To the contrary, it builds upon it.
Note that the conclusion of this argument is the phrase "the answer is no," which comes right next to the explanation for that conclusion, "since motorists with more fuel-efficient vehicles..." This allows you to eliminate choice "The first is a conclusion that is later shown to be false; the second is the evidence by which that conclusion is proven false.", as the evidence for the argument's conclusion is everything beginning with "since," not the second bolded portion.

As you assess the argument and scan the answer choices, it should become clear that you will need to determine the dean's conclusion. A few things are important in finding that: 1) note the word "but" to begin the second sentence. Transition language like that often signifies that the author is transitioning between contextual information and her main point, so you should pay even closer attention past "but" to find the conclusion there. 2) Remember the "why test" - in order to be a conclusion, a statement must be backed up with a reason "why" it's true somewhere else in the argument.
Note that the non-bolded initial clause of that sentence "cutting the marketing budget would be a terrible idea" does have a reason why: because if you did that, students wouldn't know about these great programs. The bolded portion does not have a reason why: "our unique programs cannot attract students if we do not properly market them" is given as a fact without the rest of the argument explaining why.
From that, you should see that the second bolded portion exists to support the author's conclusion. This will narrow you down to choices "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion." and "The first is a conclusion that the dean supports; the second is evidence for that conclusion.".
From there, play the answers against each other. "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion." says that the second portion is used to support the dean's conclusion, while "The first is a conclusion that the dean supports; the second is evidence for that conclusion." says that it's evidence for "that conclusion," meaning the first bolded portion. "our unique programs cannot attract students if we do not properly market them" does support the conclusion that cutting marketing would be a bad idea (choice "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion.") but it doesn't support the idea that "we should cut unnecessary costs" (choice "The first is a conclusion that the dean supports; the second is evidence for that conclusion."). So the correct answer is "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion.".

The bolded portion does not have a reason why: "our unique programs cannot attract students if we do not properly market them" is given as a fact without the rest of the argument explaining why.
From that, you should see that the second bolded portion exists to support the author's conclusion. This will narrow you down to choices "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion." and "The first is a conclusion that the dean supports; the second is evidence for that conclusion.".
From there, play the answers against each other. "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion." says that the second portion is used to support the dean's conclusion, while "The first is a conclusion that the dean supports; the second is evidence for that conclusion." says that it's evidence for "that conclusion," meaning the first bolded portion. "our unique programs cannot attract students if we do not properly market them" does support the conclusion that cutting marketing would be a bad idea (choice "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion.") but it doesn't support the idea that "we should cut unnecessary costs" (choice "The first is a conclusion that the dean supports; the second is evidence for that conclusion."). So the correct answer is "The first is a consideration that the dean agrees with; the second is support for the dean’s conclusion.".

In countries where healthcare is universal and provided free of charge by the government, visits per capita to the doctor are twice as frequent as they are in countries where healthcare is paid at least partly out-of-pocket by the consumer. Presently, governments do not have a reliable way of determining whether the symptoms for which these patients were treated for would have otherwise subsided without medical attention. However, this information does not warrant the conclusion by some universal healthcare critics that in the countries with a higher frequency of doctor visits, about half of them are unnecessary. Alternatively, in those countries where healthcare is not free, consumers often forego visits to the doctor except in cases of severe symptoms.
In the argument above, the two boldfaced portions play which of the following roles?

In the argument above, the two boldfaced portions play which of the following roles?
Tap to reveal answer
Remember that for all Method of Reasoning questions you must first deconstruct the argument before you go through process of elimination to find which answer choice best describes it. The first bolded information gives that the frequency of visits to the doctor is twice as high in those countries with free healthcare as it is in those without free healthcare. This piece of information is presented without an explanation as to why and is therefore a premise that describes the frequency of visits to the doctors between countries that do and do not have universal healthcare.
After the first bolded portion, the next portion gives a second premise, that there is no way of determining the severity of the patients’ symptoms and no way of determining whether these trips to the doctor were unnecessary. The second sentence of not-bolded information continues this by stating that the conclusion that half of the visits in countries with universal health care are unnecessary is not necessarily valid.
The second set of bolded text then gives an alternative explanation: that consumers in countries without universal health care instead avoid going to the doctor when they need to. Notice that this isn’t a conclusion, but is instead an argument against a certain conclusion.
With the argument deconstructed, you can then take a look at the answer choices. Be wary of wordplay and be very picky!
Choice "The first is a premise that the argument disputes; the second is a conclusion that has been based on that premise." may seem close to your initial analysis of the bolded portions. The first bolded portion is a premise, but it is not the premise that the argument disputes, but the conclusions that can be drawn from that premise. Additionally, the second portion is reasoning that the conclusion in the previous sentence isn’t justified rather than a conclusion in and of itself. Choice "The first is a premise that the argument disputes; the second is a conclusion that has been based on that premise." can therefore be eliminated.
Choice "The first is a premise, of which the implications are in dispute in the argument; the second is a claim presented in order to argue against deriving certain implications from that premise." matches the deconstruction of the argument. The first bolded portion is a premise whose implications (whether or not the extra doctor’s visits are warranted) are indeed under attack. The second bolded portion is a claim, arguing against the conclusion in the previous sentence. Choice "The first is a premise, of which the implications are in dispute in the argument; the second is a claim presented in order to argue against deriving certain implications from that premise." is correct.
Choice "The first is a finding, the accuracy of which is evaluated in the argument; the second is evidence presented to establish the accuracy of the finding." can be eliminated since the first bolded portion is not a finding, but a premise. Its accuracy is also not in question, so you can confidently eliminate choice "The first is a finding, the accuracy of which is evaluated in the argument; the second is evidence presented to establish the accuracy of the finding.".
Choice "The first is a premise that has been used to support a conclusion that the argument accepts; the second is that conclusion." is correct in that the first portion is a premise. However, the first conclusion reached is not accepted by the argument – it is disputed. Choice "The first is a premise that has been used to support a conclusion that the argument accepts; the second is that conclusion." can be eliminated.
Choice "The first is a conclusion that rests upon further evidence within the argument; the second supports that conclusion." can be eliminated since the first bolded portion is a premise, not a conclusion, since it does not pass the “why” test.
The correct answer is "The first is a premise, of which the implications are in dispute in the argument; the second is a claim presented in order to argue against deriving certain implications from that premise.".

Hiker: With the storm approaching quickly we need to make a decision on how to proceed. We can try to descend the mountain to seek shelter, but then we will undo our progress and lose our chance to reach the summit – and we may not make it all the way down, anyway. We can continue on our current course and hope that the storm misses us or passes quickly, but doing so risks a true disaster. So we should bivouac here, using the time before the storm to set up a safe, secure camp to weather the elements.

In Method of Reasoning questions, the correct answer must be a completely-accurate description of the argument - your goal then should be to attack each answer choice to find a word or phrase that doesn't fit. Method of Reasoning makes for good process of elimination.
Choice "Claims that her decision is the only logical course of action." is incorrect in that the hiker does not single her decision out as the ONLY logical decision: she considers the merits of two other decisions and arrives at one she feels is best. Choice "Claims that her decision is the only logical course of action." is too strong.
Choice "Chooses a course of action based on experience in similar situations." is incorrect because the concept of experience never comes up in the argument. Similarly, choice "Makes a unilateral decision by dismissing the recommendations of others." mentions the recommendations of others but in the argument as given the only options discussed come straight from the hiker herself.
Choice "Recommends a choice based on the elimination of alternative options." is correct: she eliminates two options and arrives at the third, so it is true that she recommends a course of action based on the elimination of others.
And choice "Outlines the risks and benefits of all available courses of action." is incorrect in large part because of the word "all" - you do not know that the three options she discusses are the only available options, so "all" could include others. And she does not talk about the risks associated with the third plan, so she does not discuss the risks even of "all" plans that are included.

The students have specifically expressed their concern that they can't borrow the materials from a public library, which is why they want the library open. The university administration counters with an alternative solution to the problem -- access the materials online. Accordingly, choice "The administration counters a concern with an alternative." is the correct answer. Answer choice "The administration incorrectly makes an assumption about students' preferences." is incorrect because it is not clear that the administration is assuming anything about the students' preferences; nor is it certain that, even if the administration assumes that the students will prefer online materials to hard copies, that assumption will be incorrect. Answer choice "The administration provides an explanation that it assumes will clarify its decision." is also incorrect; the administration does not explain its decision to close the library, but rather offers an alterative solution. Answer choice "The administration defends its actions by criticizing the logic of its opponents." is incorrect, as the administration does not criticize the students at all, but rather addresses their concerns. Similarly, answer choice "The administration makes an unwarranted assumption about the motives of some of the students." is also incorrect, as the administration does not address the motives of the students at all.

In this Method of Reasoning question, you're asked to describe the opposing candidate's reply, so pay particular attention to that. Note that the opponent does not supply any statistics, so choices "Supplying a statistic that undermines the incumbent’s conclusion.", "Suggesting that the incumbent’s statistic is factually inaccurate.", and "Offering a statistic that sheds additional light on the statistic supplied by the incumbent." are not accurate descriptions of the response. And he does not say that the statistic is irrelevant, just that there is more to the statistic than the incumbent had implied. The opponent points out that the unemployment rate may be more a function of the denominator (the number in the labor market) than the numerator (the number of those people without jobs), so he is saying that the statistic might not actually support the claim of the incumbent. Thus, choice "Pointing out that the incumbent cited a statistic that does not necessarily support his conclusion." is an apt description.

Diet Company Executive: Our “12-Weeks-to-Skinny” diet plan is the best in the country. Each year we send out a comprehensive survey to everyone who enrolled in this plan. The survey contains questions about everything from the quality of food in the program to the percentage of weight lost during the 12 weeks. Amazingly, last year over 80% of the survey respondents lost more than 10% of their body weight during the 12-week period, a figure unprecedented among diet companies.
The executive’s claim about the quality of the diet plan is most vulnerable to criticism on which of the following grounds?

Fairly well hidden within the executive’s claim is a data flaw relating to the survey. What if the only people who responded to the survey were those people who had successfully lost weight. The executive says “last year, over 80% of the survey respondents lost more than 10%...” Remember: “Survey respondents” is not the same as “Those who enrolled in the plan”! There could have been 1 million people who enrolled in the plan but only 50,000 lost 10% of their weight or more. If most of those 50,000 responded to the survey, and few other people did, then it would seem that a high percentage of the survey participants lost weight, when it was really only 5% of the population. Answer choice "It does not consider whether dissatisfied customers are less likely to respond to the survey." exposes this flaw and is thus correct.

For this type of “describe the flaw” method of reasoning question, you should first attack the argument to find flaws on your own and then decide which answer choice properly describes one of them. In analyzing the Town Representatives argument, you should notice that he does not actually address the specific claims made in the advertisements. Rather he just questions the motivations behind the claims. What if indeed the new cruise ship pier WILL bring in more cruise ships and ruin the charm of the town, but the ads are being paid for by a developer with questionable motivations.

For "It focuses on the motivations for the people making a particular claim without considering the motivations of other people making the same claim.", the argument does focus on the motivations but the issue is NOT that it isn’t considering the motivations of other people – the issue is that it does not address the claims. For "It directly attacks the merits of the claims made in the advertisements but does not provide evidence to support the opposing view." the argument specifically does not attack the merits of the claim so this is clearly incorrect and for "It mischaracterizes the views put forth in the advertisements and then directly attacks these mischaracterized views." it is not mischaracterizing the views. For "It fails to consider the possibility that some of these advertisements were paid for by town advocates with legitimate concerns on the effects of cruise ships.", the argument does not fail to consider this possibility as it only says “most of advertisements” were paid for by a developer. The argument acknowledges there are other ads paid by different people but is just emphasizing that most come from this person. Correct answer is "It rejects a claim by addressing the motivations for the people making it rather than by addressing its actual merits."

Recent research shows that training programs that include emphases on flexibility, highlighting activities such as yoga and pilates, are significantly more effective at preventing injury in athletes than are training programs that solely focus on strength and speed. The Bournemouth Football Club suffered fewer injuries than the Haleford Football Club this past season, so it can be concluded that Bournemouth's training program featured more flexibility activities than did the program at Haleford.

When you look at how this argument is built, recognize a few major points:
-
The only comparison drawn between methods of injury prevention pits "flexibility training" against "strength and speed training." You don't at all know that flexibility training is the best of all possible injury prevention techniques (rest? nutrition? hydration?). What if Bournemouth just did a better job of prioritizing the other, unnamed injury prevention techniques, but didn't do as much flexibility training as Haleford?
-
The amount of flexibility training is not part of the comparison - the comparison just pits "programs that include flexibility training" (whether it's a small amount of flexibility training or a large amount) against "programs that solely focus on strength and speed." The given premise does not allow for a "more vs. less" flexibility training conclusion, as it is just "has" vs. "does not have" data.
-
You don't know whether Haleford has more players, or played more games - you don't know whether the real number data (more vs. fewer injuries) is balanced enough to draw a conclusoin.
As you go to the answer choices, you'll see that choice "assumes that the consequence of one set of circumstances would not be produced by another." summarizes the flaw outlined in 1) above - the conclusion doesn't allow for other factors to be the drivers behind the injury difference. And no choices summarize 2) or 3), so "assumes that the consequence of one set of circumstances would not be produced by another." must be correct. Among the incorrect choices:
"generalizes from too few data points." points out the wrong data flaw - there is a flaw in using real numbers of injuries without a per-capita or percentage direct comparison, but the problem isn't necessarily "too few data points."
"uses its own conclusion as one of its major premises." is not the case, as the conclusion is not one of the premises - it stands alone as its own new piece of information.
"fails to consult alternative research studies." is not necessarily a flaw, as there is no reason to suspect that the studies consulted are insufficient to establish the notion that flexibility can help prevent injuries.
And "does not distinguish between incidence of injury and degree of injury." is not a flaw here as the premises and conclusion are all consistent in using the number/incidence of injuries (did an injury occur). The argument as constructed has no need to focus on severity of injury.

Because this portion is a conclusion, you can eliminate answers "The first is a premise supporting a later contention; the second is also a premise supporting that same contention." and "The first is a premise that is not necessarily true; the second is an admission of a potential flaw in the earlier premise." immediately without even considering the second half of each answer choice.
Then assess the role of the second bolded portion. Note that it modifies the main clause of the final sentence, which could stand alone without the modifier. By saying "despite their frequent improvements" the modifier bolsters that provided information, suggesting that one would think that prices for technological items would rise, and yet they have fallen. So the second portion exists to strengthen the main premise of the argument. Choice "The first is a conclusion that does not necessarily follow from a given premise; the second is a consideration meant to strengthen a premise given in support of that conclusion." provides exactly this description, so choice "The first is a conclusion that does not necessarily follow from a given premise; the second is a consideration meant to strengthen a premise given in support of that conclusion." is correct.

Many physicians cater to their patients’ insistence that they be given antibiotics for a common cold. However, these illnesses are viral in nature, and such medications have no effect on viruses. This course of treatment is troublesome, as antibiotics have dangerous side effects and unnecessary use of these drugs can lead to resistant bacteria. So clearly doctors need to stop prescribing antibiotics to treat the common cold.
Which of the following best describes the role of the two boldfaced portions above?

In any boldface critical reasoning problem, you need to carefully map out all elements of the argument. Remember that everything in a CR stimulus is a conclusion, a premise, or context. First find the conclusion, which is quite clearly the last sentence: “So clearly doctors need to stop prescribing antibiotics to treat the common cold.” To be sure, ask “why” and then map out the premises supporting this opinion. Why? Because 1. these illnesses are viral in nature, and such medications have no effect on viruses and 2. This course of treatment is troublesome, as antibiotics have dangerous side effects and unnecessary use of these drugs can lead to resistant bacteria. So it should be quite clear that the second boldfaced portion is a premise supporting the author’s conclusion. Since it is easier, start with that portion in the answer choices. "The first is a phenomenon that the argument addresses; the second is the author’s primary conclusion.", "The first is evidence used by the author to support his conclusion; the second is that conclusion.", and "The first is a circumstance that the author tries to explain; the second is the author’s primary conclusion." all refer to this premise as a conclusion so they can be confidently eliminated. For the first boldfaced portion, this part is indeed “a phenomenon that the argument addresses” so "The first is a phenomenon that the argument addresses; the second is evidence used by the author to support his position." is correct. For "The first is a circumstance that the author tries to explain; the second is that explanation.", while this portion might be “a circumstance” it is not at all what the author is trying to explain. The author is rather trying to show that this is a bad idea and must be stopped – he is not explaining why doctors do this! Therefore, both portions of "The first is a circumstance that the author tries to explain; the second is that explanation." are improperly described and this can be eliminated. Correct answer is "The first is a phenomenon that the argument addresses; the second is evidence used by the author to support his position.".

The latest adaptation in swimming pools is the saltwater pool. The water in such pools is 1/10 as salty as the ocean, approximating the salinity of the human body. Owners of such pools claim that the pools cause no chlorine irritation and that the salt water actually soothes and softens the skin. They also claim that such pools are less expensive to maintain than traditional freshwater pools. However, manufacturers of pool chemicals, such as chlorine, claim that the salt water system is more expensive to install and can leave behind a salt residue on some surfaces.

The correct answer will describe the roles of both portions in bold. The first portion describes two possible advantages of the new salt water system. The second portion replies with two disadvantages that are not directly related to the two advantages listed in the first statement. Choice "The first portion lists two potential advantages of implementing a new system; the second portion lists an unrelated pair of possible disadvantages of implementing the system." correctly describes the roles of each of these statements. Choice "The first portion lists two possible advantages of implementing a new system; the second portion directly refutes those advantages." is very close to this, but incorrectly describes the second portion as directly refuting the advantages stated in the first. Choice "The first portion is an unproven claim regarding a new system; the second portion is evidence supporting this claim.", "The first portion is the main conclusion of the argument; the second portion is an unintended consequence of the main conclusion.", and "The first portion is evidence for a claim; the second portion is a competing claim." each describe both portions incorrectly.

It is generally believed that an Indian tribe known as “The Red Paint People” first occupied the coast of Maine in approximately 3000 B.C. This name was given to the Indians because their graves contained quantities of a red pigment (iron ochre) that they presumably used to decorate their faces and bodies. However, recently discovered Indian grave sites on the coast of Maine that contain these same red pigments have been conclusively dated to 4000 B.C. Therefore, the “Red Paint People” must have occupied the coast of Maine much earlier than archaeologists previously believed.
In the argument above, the two portions in boldface play which of the following roles?

In this argument, the two boldfaced sections are each conclusions. The first is a conclusion that most people accept as true, and the second is the main conclusion of the argument, which refutes the first conclusion using the evidence in the third sentence. Answer choice "The first is a conclusion that is generally accepted as true; the second is a conclusion that refutes it." is thus correct. In "The first is a commonly held belief that the argument seeks to refute; the second is evidence used in that refutation.", the first portion is described perfectly but the second part is incorrect: the last boldface portion is not evidence. In "The first is a generalization that the argument accepts as true; the second is the main conclusion of the argument.", the second portion is correct (it is the main conclusion) but the first part is incorrect. The term “generalization” is not accurate but more importantly the argument does NOT accept it as true, it refutes it. "The first is evidence used to support a conclusion that the argument opposes; the second is the main conclusion of the argument." is probably the most difficult incorrect answer. The second portion is correct but the first is not: the first portion is not evidence but rather a widely accepted conclusion whose evidence is not given in this argument. In "The first is an intermediate conclusion that is generally accepted as true; the second is the main conclusion of the argument.", the first is definitely not an intermediate conclusion, so it is incorrect. Answer is "The first is a conclusion that is generally accepted as true; the second is a conclusion that refutes it.".

A recent survey has found that in areas where marijuana is legal, almost 20% of the people admit to using it occasionally, whereas in areas where it is illegal, less that 5% people do so. But these facts do not warrant the conclusion drawn by some commentators that in areas where marijuana is legal, more people use it. Clearly, in areas where marijuana is illegal, people do not readily admit to using it even if they are doing so.

The first statement gives us a correlation between percentage of people of an area who admit to using marijuana and the legal status of marijuana in that area. The argument then states that this correlation has led some to infer that people use marijuana more in areas where it is legal. The second boldface portion explains why this inference is not necessarily warranted by offering an alternative explanation.
"The first is a claim, the argument disputes; the second is a conclusion based on that claim.": Incorrect. The claim made in the first statement is not disputed in the argument. At issue is the inference drawn from that claim.
"The first is a claim used to support a conclusion that the argument accepts; the second is that conclusion.": Incorrect. The second boldfaced portion is not the argument’s conclusion.
"The first is evidence to support a conclusion for which the argument provides further evidence; the second is the main conclusion of the argument.": Incorrect. The first statement is used to support a conclusion that the argument rejects. The second bold portion is not the argument’s conclusion.
"The first is a finding whose implications are at issue in the argument; the second is a claim presented in order to argue against deriving certain implications from that finding.": Correct. The first statement is a finding whose implications are under dispute. The second statement is a claim presented to argue against deriving certain implications. Hence the role of the two statements is correctly identified.
"The first is a finding whose accuracy is evaluated in the argument; the second is evidence presented to establish that the finding is accurate.": Incorrect. The accuracy of the first statement is never questioned, nor is the second used as evidence to establish the finding.

Genetically-altered trees have been developed that can remove toxins from the air more quickly than naturally-occurring trees can. However, we will not know whether the modified trees adversely affect the environment without actually planting them and carefully monitoring the environment for at least several years. Since this might cause irrevocable harm to the surrounding area, we should resist the temptation to use these trees until long-term research in a closed environment has been completed.
Which of the following best describes the method of argument used in the argument above?

The course of action that is advised against is planting genetically-altered trees to remove toxins. The similar, but limited, course of action is long-term research involving the planting of such trees in a closed environment. Positive results from the limited action – no serious damage to the environment – need to be seen; otherwise, we should “resist the temptation” to plant the trees in the open.
"After detailing concerns with two approaches to a problem, both are discarded in favor of an approach that does not raise the same concerns." This choice mentions two approaches, and then “another approach,” making for three approaches in total. However, only two approaches are ever mentioned: planting them in the general environment, or planting them in a closed environment.
"A possible future scenario is described as being unrealistic, while a different scenario is given more credence." No particular scenario is ever described as unrealistic.
"An experiment is recommended to determine the benefits of a new approach to a longstanding problem for which no other comparable solution is known." This choice starts out fine, but we cannot say that “no other comparable solution is known.” If anything, we are told that naturally occurring trees can be used to remove toxins, though slowly.
"The benefits and disadvantages of two remedial courses of action are weighed." It is not clear that the argument presents two distinct remedies. Even if we consider planting the trees in an open environment to be one remedy and planting the trees in a closed environment to be another remedy, no disadvantages to planting the trees in a closed environment are mentioned. If we consider planting naturally-occurring trees to be a second approach, then this answer choice does not even mention long-term research.
The correct answer is "A course of action is advised against unless a similar, but limited, course of action produces positive results."

A large company has recently increased its dividend payments to shareholders. Shareholders had previously been worried about the company's stock price, but are now relieved since increasing dividends generally boosts a company's stock price. However, the shareholders' optimism may be ill-founded since spending money on the payment of dividends often indicates that the company has exhausted more lucrative investments for its cash reserves and that the stock price will likely fall in the longer run.
In the argument above, the two bold-faced portions play which of the following roles?

This Boldface problem rewards those who can adeptly deconstruct arguments and find conclusions. Here the main conclusion of the argument is "the shareholders' optimism may be ill-founded" - you know that this is a conclusion because it is adjacent to the word "since" (which gives a reason for the conclusion - remember, conclusions must pass the "why test" in which some other portion of the argument tries to explain why it is true). And you know that it's the main conclusion because it follows "however," a signal that the author has introduced an idea and then transitioned to her main point.
With this knowledge you're ready to attack the answer choices and pick apart the subtle difference between popular choices. The first bolded portion is evidence that is used to support a conclusion (just not the main conclusion) - it's a reason that some shareholders believe that they do not have be be worried about the company's stock price.
The second bolded portion is evidence for the main conclusion - it's the reason that the shareholders' optimism may be unfounded.When you attack the answer choices, note that "The first is evidence that supports a conclusion; the second is that conclusion." and "The first is a premise that is accepted as true; the second is a conclusion that is contrary to the premise." each clearly mischaracterize the second bolded portion as a conclusion when in fact it is a premise.
Among the other choices, recognize that the goal of the argument - as evidenced by the conclusion - is to show that the shareholders' optimism is misplaced, NOT to clarify the initial fact. Again, this goes back to isolating and fixating on the conclusion. This is why choice "The first describes evidence that supports a conclusion; the second gives a reason for questioning that support." is correct: it properly notes the role of the second bolded portion, to support the conclusion that the optimism is unfounded (which, conceptually, is the same thing as questioning the shareholders' logic). Choices "The first describes the circumstance that the argument seeks to explain; the second provides evidence in support of the explanation that the argument seeks to establish." and "The first is a premise that is accepted as true; the second seeks to clarify the original premise." are each tempting, but each suggests that the purpose of the argument is to clarify the fact in the first sentence, when in fact the conclusion is clear in its intention to question the logic of the shareholders.
