Experience the Quality With Free LSAT Exam Questions That Helps Candidates Pass

The conclusion makes a causal claim. Choice B strengthens it by showing that when individuals change behavior (from sedentary to daily walking), they subsequently experience a measurable decrease in blood pressure. This before-and-after evidence reduces the possibility that preexisting differences explain the correlation.

Choice A introduces a rival explanation (diet), which weakens instead of strengthening. Choice C is irrelevant—it focuses on mood, not blood pressure. Choice D raises demographic differences but doesn’t strengthen causation. LSAT strengtheners work by demonstrating outcome changes with input changes, making B the strongest support.

The passage neutrally presents two sides—benefits and risks—and concludes the debate reflects complexity. Thus, the purpose is balanced evaluation, not endorsement.

Choice A and C pick sides. Choice D contradicts the passage. RC purpose questions often ask for recognition of nuanced discussion, making B correct.

The layering shows revisions across generations, suggesting art was dynamic and evolving, not one-time works. Thus, the supported inference is that cave art reflected ongoing cultural practice.

Choice A contradicts the evidence. Choice C is unsupported—the passage doesn’t discuss dating accuracy. Choice D is speculative and unsupported. Inference questions require restrained conclusions consistent with evidence, so B is correct.

The researcher’s conclusion depends on ruling out alternative explanations. If diet or medication caused the decrease, the reasoning collapses. Thus, A is necessary.

Choices B, C, and D are unnecessary details. LSAT assumption questions typically test whether alternative causes are ruled out—A is correct.

The argument is flawed in several ways: (A) assumes causation, (B) ignores selection bias, and (C) confuses preference with proof. Since all apply, D is correct.

This mirrors classic LSAT advertising flaw questions.
