Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches.Unfortunately, electronic switches that are this small cannot withstand intense radiation辐射.Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage.The switches will, however, be slower than electronic switches and the chip will contain only 12,000 switches.

For there to be a market for Micro-Mechanics’ chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:

A.There will be applications in which the speed attainable by an electronic switch is not essential.

B.Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics’ chip will be.

C.There will be applications for computer chips in environments where the chips may have to survive intense radiation.

D.Some devices in which computer chips will be used will have other components成分，要素，部分 that will be able to function during or after exposure to radiation.

E.Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.
为什么C对对？

原文由M-M chips可以不受辐射危害，比Electronic computer chips好，根据这个优势而推出有M-M chips的市场这个结论。同时，它比后者慢并且容量小。C选项说有一种装置可以让computer chips不受辐射危害。那么M-M chips就没有竞争力了。

好吧，我也选的C，但是答案是E。。。
