There was
school; the
shortened by a full ten minutes.

Because “children” is an irregularly formed plural, the normal apostrophe rules do not apply. The apostrophe goes before the "s": "There was outrage in the elementary school; the children’s recess was shortened by a full ten minutes."

Magazine advertisement’s from the 1950s frequently portrayed women cooking, cleaning, and playing with children. No error
advertisement's
1950s
women
cleaning, and
No error
Explanation
The error in the sentence is “advertisement’s,” which should be written as “advertisements.” An apostrophe should be used to show possession (e.g. "Bob’s cat") or when combining two words in a contraction (ex. "it is" can be written as "it’s"). This sentence is referring to magazine advertisements from the 1950s, but the “women cooking, cleaning, and playing” in the magazine advertisements do not belong to the magazine advertisements.
