Good question, Patrick, and thanks for asking. The problem with answer A here is the comparative nature of the answer. Our stimulus told us that prices have gone down on some unfashionable materials and have gone up on some newly fashionable ones, and so it is reasonable to infer that fashion does have an impact on price. That's not enough, though, to determine that fashion is always more important than other factors. For example, we haven't examined the effects of things like supply and demand - maybe prices go up not because of how fashionable something is, but because of supply problems? That may be indirectly caused by changes in fashion - more fashionable items sell more, driving up demand and possibly leading to reduced supply - but that doesn't mean fashion is the direct cause. Or, maybe in some cases fashion has no impact at all: if a completely unfashionable item was spun from 14k gold thread and studded with rubies and diamonds, might that be very expensive notwithstanding the fact that most people would not be caught dead wearing it? Comparisons like this, setting one thing as being more important, better, more influential, etc. than another, when all we know is that the one thing may have SOME influence, is a pretty common problem, especially in Must Be True questions.
The generalization here is essentially a Principle - a guideline or rule to be followed. Principles can be found in Strengthen, Weaken, Must Be True, Cannot Be True, and Parallel Reasoning questions, among others. Your approach to the question and answer choices will vary based on what question type it is. If it's a Strengthen question, you will want to find the generalization/Principle that helps the conclusion the most, and so strong language like "most" and "best" and "only" will be welcomed as useful concepts. This question, which I would probably classify as a "Most Strongly Supported" (a type of Must Be True), calls for a softer, milder answer, one that can be proven based on the stimulus. Strong answers in these questions are hard to defend, and we don't want that.
One more thing to consider here, and that is a comparison between answers A and E. If answer A is correct, doesn't it also force answer E to be correct? If fashion is more important than materials, doesn't that prove that cultural trends (i.e. fashion) are important? That's what we call the uniqueness principle of answer choices. When one answer, if correct, forces another to also be correct, then the one doing the forcing cannot be the credited response. Perhaps the one being forced is right, or perhaps they are both wrong. If in your materials you came across a question about a headache relieving pill that had answers about one person's headache being relieved faster than another's, and also about one person getting relief at least as quickly as the other, then you have seen the uniqueness principle in action. It doesn't come up often, but when it does it is a great way to eliminate what could be a very attractive wrong answer. Take a look at those two answers in that light and see if that makes some sense.
Keep at it! We're here for you if you need us!
