WeakenDiff: Medium

Logic Breakdown

Passage Summary: Two treatments work equally well, but one is faster and cheaper, so the author says we should definitely use the faster, cheaper one.

Conclusion: Treatment X is a better choice than Treatment Y for treating these specific illnesses.

Reasoning: Both treatments produce identical health benefits, but Treatment X is faster and costs less than Treatment Y.

Analysis: The argument assumes that speed and cost are the only relevant factors once medical efficacy is equalized. To weaken this, we need to find a 'hidden cost' or a disadvantage of Treatment X that isn't about money or time. For example, if Treatment X has much more severe side effects than Treatment Y, the 'cheaper' option might not be the 'better' one. Look for an answer choice that introduces a significant downside to Treatment X or a unique benefit to Treatment Y that justifies the extra time and expense.

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

Correct Answer
A
Evidence that X has harmful side effects (even if initially in lab animals) undercuts the recommendation to prefer X, because safety is a major clinical consideration the argument ignored. Equal short-term benefits and lower costs don’t justify preference if X poses unique harms.
