Question Type:
Sufficient Assumption
Stimulus Breakdown:
Premises:
1. manufactured pattern → tailor alters pattern for future fabric distortion
2. clothing not worn by person whose measurements match pattern → tailor alters pattern to fit wearer
Conclusion:
A professional tailor always adjusts the pattern to fit the wearer.
Answer Anticipation:
The premises tell us that tailors will alter a pattern to fit the wearer, but only if a certain condition is met (the clothing will not be worn by someone whose measurements exactly match the pattern). If we assume that professional tailors never make clothing for people whose measurements match the pattern size, we can conclude that those tailors always adjust the patterns that they use.
Correct answer:
D
Answer choice analysis:
(A) In this argument, an assumption about "most" manufactured patterns will not guarantee a conclusion that states a tailor will always adjust a pattern.
(B) This answer addresses one gap in the argument: the premises are about tailors, but the conclusion specifically mentions "a professional tailor." However, an answer choice about "some tailors" doesn't completely fill this gap, and this is not the only gap in the argument that needs to be addressed.
(C) Being one of the "best" did not play any role in the original argument, so this answer does not connect our premises to the conclusion.
(D) Bingo. This matches our prediction.
(E) A tailor's ability to estimate fabric distortion doesn't guarantee that they will always adjust the patterns that they use.
Takeaway/Pattern:
Clearly identifying the argument core—the premises and conclusion of the argument—will often help us accurately predict the correct answer to a Sufficient Assumption question.
