An experimental microwave clothes dryerheats neither air nor cloth. Rather, it heats water on clothes, thereby savingelectricity and protecting delicate fibers by operating at a lower temperature.Microwaves are waves that usually heat metal objects, but developers of amicrowave dryer are perfecting a process that will prevent thin metal objectssuch as hairpins from heating up and burning clothes.
Whichof the following, if true, most strongly indicates that the process, whenperfected, will be insufficient to make the dryer readily marketable?
(A) Metal snap fasteners on clothes thatare commonly put into drying machines are about the same thickness as mosthairpins.
(B) Many clothes that are currentlyplaced into mechanical dryers are not placed there along with hairpins or otherthin metal objects.
(C) The experimental microwave dryer usesmore electricity than future, improved models would be expected to use.
(D) Drying clothes with the process wouldnot cause more shrinkage than the currently used mechanical drying processcauses.（E）
(E) Many clothes that are frequentlymachine-dried by prospective customers incorporate thick metal parts such asdecorative brass studs or buttons.

答案是E 难道意思是因为传统的方法就已经不会让金属弄坏衣服了所以新方法其实是不必要的
