On average, schools that provide an extra recess period each day during which children are allowed unstructured play score higher on state aptitude tests that schools that do not provide such a recess period. Therefore, the test scores at Malthus Elementary would likely improve if the school adds a recess period of unstructured play.

Which of the following, if true, would most weaken the argument?

Nearly all of the schools providing the extra unstructured recess period provided it to reward students for their performance on the aptitude tests.
Schools that add an extra period of recess perform better than schools that merely switch from structured to unstructured recess.
Malthus already enjoys above average scores on the aptitude tests in question.
An extra recess period allows students less time to study for their aptitude tests.

Because you are asked to weaken the author’s reasoning, and reasoning requires a conclusion, an argument will always be present. In order to maximize your
chances of success you must identify, isolate, and assess the premises and the conclusion of the argument.

In this case

So the conclusion over here is the test scores at Malthus Elementary would likely improve if the school adds a recess period of unstructured play.

Focus on the conclusion. Almost all correct Weaken answer choices impact the conclusion.

To weaken a conditional conclusion, attack the necessary condition by showing that the necessary condition does not need to occur in order for
the sufficient condition to occur.

The conditional statement over here is On average, schools that provide an extra recess period each day during which children are allowed unstructured play score higher on state aptitude tests that schools that do not provide such a recess period
What if it is other way around, the school provided this extra recess period each day because the students were scoring high on state aptitude test.

Remember this for all weaken Questions:
The conclusion is the part of the argument that is most likely to be attacked, but the correct answer choice will not simply contradict the
conclusion. Instead, the correct answer will undermine the conclusion by showing that the conclusion fails to account for some element or possibility.
