The snack food market has recently seen an explosion in theproduction and sales of "100- Calorie packs," individually wrappedportions of snack foods sized to provide exactly 100 calories per portion.These packs cost substantially more per ounce-they sell for nearly same priceas traditionally sized portions, which are typically two to three times theirsize - but consumers have been purchasing them with greater and greaterfrequency. One possible explanation is convenience: Consumers may be relatively unconcerned with theirsubjective impression of the small packs, and willing to pay more to avoidhaving to measure out their portions. Another possible explanation is that 100-calorie pack, at least in the case of snacks for which it has sold well,represents the smallest portion that still looks and feels"substantial" enough to appeal to dieters who lack the self-controlto limit their consumption of snacks from larger packages.
Which of thefollowing, if true, would supportone of the given explanation and undermine the other?
A. Consumers arewilling to pay exactly the same price for 100-calorie packs sold in vendingmachine as for traditionally sized snack portions sold in vending machine.
B. A large numberof buyers of 100-calorie packs consume them as light desserts after large mealsthat have left them feeling too full for traditionally sized snack food.
C. Although the100-calorie packs have begun to sell well across a large variety ofdemographics, busy young professionals were the first group to purchase themfrequently.
D. Because the100-calorie packs require more packaging per ounce of food than thetraditionally sized portions do, manufacturers must charge more per ounce tomake the same relative profit as on traditionally sized portions.
E. Sales of 100-calorie packs have beenuniformly poor at stores where they are displayed alongside traditionally sizedportions, even for the same snacks whose 100-calorie packs are bestsellers atother stores.
用排除法选了e，但是对e还是有点迷惑 --》 可以理解e是攻击了第一个解释（人们为了方便才买了小包装的，但如果放在大包装旁边的话，小包装的销量就下降，那么就削弱了这个解释）但是我不是很理解第二个解释，从文章给的信息来解读，第二个解释的意思是Another possible explanation is that 100- calorie pack, at least in the case of snacks for which it has sold well, represents the smallest portion that still looks and feels "substantial" enough to appeal to dieters who lack the self-control to limit their consumption of snacks from larger packages. --》对于节食者来说，小包装感觉起来和大包装差不多（looks and feels substantial enough)，所以他们可以借此来降低他们食用大包装。
可是如果是这样的话，对于解释2来说，小包装和大包装就算是摆在一起的话，节食者也应该选择小包装才对，因为是为了减少食用snacks。那答案e其实也是削弱了第二个解释。看了ron的视频，他对选项e的解释是- E: this work against 1because if they were put next to the traditional sized snacks and had poor salethen it went against 1. But it explains why people bought it despite it wasnext to traditional snacks > because they look like real snacks.
难道是将e的前后两部分拆分来看？sales of 100-calories packs have.... (这个部分削弱解释1）,even for the same snacks whose 100-c are best sellers at other stores （支持解释2）？
求大神指教！
