2. The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would have just the same sort of drawback, since things would fall off the shelves’ edges into the rear corners.
Which of the following is presupposed in the argument against introducing rotating shelves?
(A) Refrigerators would not be made so that their interior space is cylindrical.
(B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.
(C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.
(D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.（A）
(E) Rotating shelves would be designed to rotate only while the refrigerator door was open.
这题真是一点思路也没有
请教大家了
谢谢
原文说冷冻食品损坏是因为他们搁置在看不见的角落里，所以设计一个旋转的架子让食品有同等的顺序被取用。
问削弱？
A说冰箱里面是圆柱形的所以不能放旋转的架子。（这一点我觉得有点奇怪）
谢谢leeon
请问A如何削弱啊
关键是理解句子Refrigerators would not be made so that their interior space is cylindrical.我的理解 that their interior space is cylindrical 是定语从句修饰refrigerator，so that 在这里不是连在一起的。不知对不对。
C错在说设计上的改变无法解决腐坏问题，直接把题干否定了，肯定不是presupposition.
同意楼上的理解。
其实这题大家都没怎么读懂题目……
还是有点点
I did this wrong. I misread the question. It was asking for an assumption and I was thinking about a conclusion.
Thanks to Hawkinxie.
这题，问的是assumption啊！
当然是A。
argument是即使换成转盘式，也不能保证食品不掉到背后去。
那么前提就是这个冰箱的内壁不是圆柱的，否则的话，圆柱型的冰箱，里面转盘做成圆的，食品怎么可能掉出去呢？
