What does the Question Stem tell us?
Strengthen (looks like Sufficient Assumption at first, but it's only asking which answer provides the "most support")
Break down the Stimulus:
Conclusion: M will probably be a capsule.
Evidence: The company making M makes all its meds in house, but it can't do soft-gel. Meds that taste bad are ususally made in tablet, capsule, or soft-gel. M couldn't be made in tablet form, because of some heat thing associated with making it.
Any prephrase?
Hmmm, if we start with tablet, capsule, and soft-gel as our three options, and the author rules out tablet and soft-gel, then aren't we left with capsule. Isn't her conclusion right already? It would be. But who said we're starting with tablet, capsule, and soft-gel as our three options? That's only the case if we have a med that tastes bad. Does M taste bad? We never heard that, and that's a critical missing piece of this argument.
Correct answer:
B
Answer choice analysis:
A) This would weaken the argument.
B) Bingo! This question allowed for such a precise pre-phrase, we should really be scanning for this answer and barely (or not) reading any others.
C) Doesn't make a difference, since we already know we're not using soft gel.
D) This weakens. M has a low melting point, so it would likely be soft-gel, according to this answer.
E) We don't need to rank tablet / capsule / soft-gel against each other in terms of taste. We already know we're not using tablet or soft-gel. We're just wondering if we're stuck with capsule as our final option (based on whether or not M has a bad taste).
Takeaway/Pattern: Although this was worded technically as Strengthen, it played out like Sufficient Assumption, because the argument was ALMOST a complete circuit of logic. We were just missing one crucial fact: M tastes bad. If you read an argument and it FEELS like it's actually logically sound, look for some tiny nuance/shift you missed. The correct answer just needs to patch up that one fault.
