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. 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:

B.Switches used on electronic chips that contain only 12,000 switches are morevulnerable to radiation damage than the switches on Micro-Mechanics's chip willbe. C.There will be applications for computer chips in environments where the chipsmay have to survive intense radiation. D.Some devices in which computer chips will be used will have other componentsthat will be able to function during or after exposure to radiation. E.Manufacturers are able to protect electronic computer chips against exposure tointense radiation, where this protection is necessary.
THX for your answer! 原文如下:Electroniccomputer chips made of tiny silicon wafers now regularly contain millions ofelectronic switches.

B项说原来那种switches和同样的只有12000的新产品来说更容易受辐射.原文说的12000的只是新的产品中的啊,没说旧的swithces有多少~
最后说E,说法是“Manufacturers are able to protect electronic computer chips against exposure to intense radiation” ,关键是这个are able to,但是没提到芯片,也就是说,制造商可以保护电子芯片不受辐射,并不一定需要机械芯片,因此对机械芯片的市场特点肯定是想违背的。。。
