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

The claim is comparative: “15% better than Brand X.” But from this, the ad concludes superiority overall, suggesting absolute effectiveness. That’s flawed because Brand X may itself be poor at stain removal; being 15% better than a weak competitor doesn’t prove excellence. Choice C directly identifies this flaw of using relative comparison to imply absolute superiority.

Choice A misframes the issue; percentage differences can matter. Choice B is true but not essential to the flaw; even one comparison might suffice if well-framed. Choice D is irrelevant because the stimulus didn’t mention satisfaction. LSAT frequently tests the leap from relative to absolute claims, and C captures it best.

The passage neutrally acknowledges both perspectives and concludes media plays dual roles. Thus, the purpose is balanced evaluation.

Choices A, C, and D are one-sided or false. LSAT RC purpose questions often emphasize nuance—B is correct.

Choice A shows causation: the riders who used bikes would otherwise have driven cars, so the program directly reduced congestion.

Choice B and D are neutral details. Choice C introduces an alternative explanation (fuel prices). Strengthening causation requires demonstrating substitution from driving to biking, which A provides.

The company attributes weight loss to the supplement. Choice A shows a confound: stricter diet could explain results, undermining the causal claim.

Choice B is irrelevant to weight loss. Choice C equalizes exercise but doesn’t weaken. Choice D relates to satisfaction, not outcomes. LSAT weakening questions often involve rival causes, making A correct.

The economist links higher taxes with better school funding, concluding that raising taxes causes improvement. For this to hold, it must be true that the additional revenue is allocated to education. Without that assumption, tax increases might fund unrelated programs, undermining the conclusion. Thus, B states the necessary assumption.

Choice A describes resident preferences but doesn’t guarantee revenue allocation. Choice C is an outcome, not a linking assumption. Choice D is speculative and not required. Assumption questions test the hidden bridge between evidence and conclusion, and here, allocation of revenue is that critical link.
