LSAT 30. Sec 4. Q 20.
Wow, what an interesting question. Usually I only contribute advice if I believe the Question to be structurally flawed, but this question is interesting enough for me to dedicate time to writing about it.
This is a strengthen question, but more importantly the stem says “most strengthens”. The “most” part of STRENGTHEN question stems is usually taken for granted, because the answer choices usually only have one answer that strengthens the question. This is not the case with this question, which is part of why it is perceived by many as being so difficult.
The argument is:
Premise: The introduction of a new drug should be contingent upon having a good understanding of its social impact.
Premise: The social impact of the new AH is far from clear.
Conclusion: There should be a general reduction in the pace of bringing new drugs that are now being tested to the marketplace.
Prephrasing the argument led me to believe the answer might be something like “new drugs that are now being tested, for which the social impact is not well understood, will be brought to market unless there is a general reduction in the pace of which these drugs are brought to market.” Of course, question creators would change some of the terminology to disguise the answer. Still, I did not incorporate the AH into my prephrasing, partly because it is virtually extraneous information to the conclusion in the stimulus. However, I was on the lookout for how it might fit into creating an answer that would sound similar to my prephrase.
I’ll start by saying that Answers C and D are irrelevant. Some students may be fooled by answer E, so I’ll discuss it briefly.
Answer E states: If most new drugs should be on the market, then the new antihistamine (AH) should be on the market. I’ve read that some students believe that the word “only” affects the answer, so I have rephrased the answer to show that the word “only” has nothing to do with whether the answer strengthens the argument. The fact is, this answer has nothing to do with “pace” of new drugs being released. It doesn’t strengthen the conclusion that suggests that the pace should be slowed.
Another student suggested that E would be correct if instead of “most new drugs”, the answer read “ALL new drugs”. This might would certainly suggest that the new AH should be on the market, (even though it’s contradictory with the premise: contingent upon having a good understanding of its social impact—which would weaken the argument in itself), but the fact remains, that the argument’s conclusion has nothing to do with whether the new AH should be on the market. The conclusion only suggests that the pace of new drugs being brought to market should be slowed.
So yes, Answer E is bordering being irrelevant or weakening the argument.
Now for what makes the question so unique (and great). Answer B is a very attractive answer, and many students choose it. It’s attractive because it DOES “strengthen” the argument. However, it does NOT “most strengthen” the argument. Answer A unequivocally MOST STRENGTHENS the argument (which is usually difficult to prove, so most LSAT questions that ask for Most Strengthen only give one answer choice that even Strengthens the argument).
Answer A:
The social impact of the new AH is much better understood than that of MOST new drugs being tested.
Answer B:
The social impact of SOME of the new drugs being tested is poorly understood.
Answer B strengthens the argument because it makes it known that there is at least one drug that is being tested that has a social impact that is poorly understood. Otherwise, ALL of the drugs currently being tested could very well have their social impact completely known. Therefore, the new drugs could be brought to market immediately if their social impact was good, or abandoned if their social impact was bad (or whatever other action is prudent, as the criterion of “having a good understanding of its social impact” has been met). There would be no need to slow the pace of bringing new drugs to market if social impact was the sole criterion to measure whether they should be released, and the social impacts for these drugs were already known. Therefore, the argument is strengthened.
However, Answer A MOST STRENGTHENS the argument.
Answer A suggests that MOST of the new drugs being tested do not rise to the understanding level of the new AH, which is described as “far from clear”. “Far from clear” is definitely not “a good understanding”. Therefore, it can be concluded that social impact of MOST new drugs being tested has not risen to the standard of “a good understanding” and are not ready to be brought to market if the standard in the premise is respected (that the marketing of drugs should be contingent upon having a good understanding of its social impact).
It boils down to this: the term MOST strengthens more than SOME in this case. Answer B states that the social impact of SOME new drugs being tested is poorly understood, and Answer A states that the social impact of MOST new drugs being tested is poorly understood. Although you can’t tell for certain under which scenario there may be more poorly understood new drugs being tested, MOST is definitely stronger language than SOME.
If an argument was structured like this:
Premise: Mary is bringing apple pie to her class for a treat.
Premise: All the students in Mary’s class love apples.
Conclusion: Therefore, all the students in Mary’s class will love Mary’s apple pie.
Which one strengthens the argument more?
1. SOME students in Mary’s class state that pie is their favorite food.
2. MOST students in Mary’s class state that pie is their favorite food.
It’s that simple. MOST is stronger than SOME.
Just as “ALL students in Mary’s class state that pie is their favorite food” would strengthen the argument even more.
Just as “ALL students in Mary’s class state that APPLE pie is their favorite food” would strengthen the argument even more than that.
What we don’t see on the LSAT is judgment calls that are ambiguous like having to select from only these two choices for a MOST STRENGTHEN question:
1. SOME students in Mary’s class state that APPLE pie is their favorite food.
2. MOST students in Mary’s class state that pie is their favorite food.
This would be a judgment call on whether one believes that whether knowing that SOME students like APPLE PIE (a more specific term) is more strengthening to an argument over knowing whether MOST students like PIE (a less specific term). Both strengthen the argument, but it can’t be determined with certainty which strengthens the argument more.
