[求助]大全16-2

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.

why A? and what is the meaning of the question? thank you very much

多谢dashasha，你的讲解我明白了，但我还是不明白Which of the following is presupposed in the argument against introducing rotating shelves，和Refrigerators would not be made so that their interior space is cylindrical，这两句话得意思，能帮忙翻译一下吗？

问题是:下面哪个选项是在反对引进旋转架子的论证中事先假定的呢?

第二句,不会有内部是圆柱体的冰箱

多谢，这次是彻底明白了。题干中得rotating shelves的前提是冰箱内部还是方型得，对吧！这样Ａ　答案就成立了。
