[求助]大全-16-2. 看了讨论依然不懂

大全-16-2.      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.

这个题,我仔细看了CD上的讨论但是还是不懂啊55555

我选的是C  也不太懂A的意思,

如果冰箱内壳是正方体 里面是圆形架子 东西当然会掉下去

如果冰箱内壳是圆柱体,圆形架子怎么不可以呢,

难道题目的意思是不能改变冰箱内壳的形状????

A means the interior spaces of Refrigerators can't be made to be cylindrical.If the interior spaces can't be cylindrical,you introduce a rotating shelfs, food will drop from the edge of the shelf into the rear corners.

Refrigerators would not be made so (that their interior space is cylindrical).

I did wrong answer too.
