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.

   (E) Rotating shelves would be designed to rotate

       only while the refrigerator door was open.

选a ， 证明方法不可行。

我有个疑惑。 就是e ， 若desinged to rotate 只有在冰箱门开的情况下才行的话， refrigerated food spoils  就更不能避免了。 所以我选 e 了

可以给我讲讲为什么ｅ错了么？

It is an assumption type of question. E is not a required condition for the argument.

前提是冰箱内部空间不能被做成圆柱体,那题目中round shelves that rotate是做在方的冰箱中的圆型可以转动的架子咯?
