24. (A)
Question Type: Inference
This is an inference question in disguise. "Proposition" is codeword for conclusion, so this question is asking us to draw a conclusion, or inference, from the information in the passage. On inference questions, we want the answer that is easiest to prove given the information in the passage. Answer (A) uses soft language that is difficult to argue with: can contribute to successful product design.
(B) is incorrect, as we don’t know if companies "traditionally" conduct these surveys, nor do we know if these surveys are "extensive."
(C) is wrong as we have no evidence to indicate that companies aim for specific "market niches."
(D) says "a car will have unappealing features." This is tough to justify.
(E) places external features in opposition to internal features. The passage does not explicitly distinguish between the two.
