Question ID:PT71 S1 Q6 Passage:A recent taste test reveals that most people like low-fat chocolate ice cream as much as its full-fat counterpart. Previous tests with vanilla ice cream found that people tended to dislike low-fat versions, complaining of a harsher taste. Chemists point out that chocolate is a very complex flavor, requiring around 500 distinct chemical compounds to produce it. Hence, this complexity probably masks any difference in taste due to the lack of fat. Stem:Which one of the following, if true, most strengthens the argument? Correct Answer Choice:DChoice A:Most people prefer full-fat chocolate ice cream to full-fat vanilla ice cream. Choice B:The subjects of the previous tests were not informed of the difference in fat content. Choice C:The more distinct compounds required to produce a flavor, the better people like it. Choice D:Vanilla is known to be a significantly less complex flavor than chocolate. Choice E:Most people are aware of the chemical complexities of different flavors.
