Problem 1 - Entrance Test

A government policy introduced in 2020 mandates that all schools provide free textbooks. A recent report shows that student pass rates in public schools have increased by 15% since 2020. Which assumption underlies this claim?

Correct: C

The argument assumes that the free textbook policy directly caused the pass rate increase. Choice C identifies the causal link by ruling out alternate explanations, which is essential for the argument's validity. Other options either overgeneralize or focus on timing.
