Three elements of the set—1, 2, and 3—fit this criterion.

None of choices fit this criterion, so the correct answer is none.

, and both are positive integers, so both will be between 1 and 15 inclusive. Since both are prime numbers - numbers with exactly two factors, 1 and the number itself - both are elements of the set

There are two ways to select two of these numbers so that their sum is 16 - 3 and 13, and 5 and 11.

If we select and , or vice versa, then .

If we select and , or vice versa, then .

Therefore, it is unclear whether or 50 is greater.

, so is the positive or negative square root of 64; those are 8 and , respectively.

Two numbers - and 8 - have absolute value 8, so if , either or .

and , but without further information, it cannot be determined which is the greater, if either.
