GWD-27-Q2,急求解释

GWD-27-Q2
Electronic computer chips made of tiny silicon wafers now regularly contain millions if 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:

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 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.
请有识之士指点: 我选的是B, 答案是E,请问为什么啊?

顶！说得不错

题目说得是Electronic computer chips有个缺点：cannot withstand intense radiation，而Micro-Mechanics chips得优点就是避免了radiation damage，但是它得缺点是switches slower，题目是（这里暂且看为结论）因为优点，Micro-Mechanics chips有market，must be true题型
E说得是Electronic computer chips可以避免 intense radiation，那么Micro-Mechanics chips相比较之下就没什么优点了，不能得出结论

LZ看错了,B里面的vulnerable和原文的invulnerable. B就是说这些现有的电子的芯片,即使也用12000个转换器,也是易受攻击的.这是对那种新的芯片有市场的一个支持

谢谢楼上的解释,不过还是有些不理解:选项B中,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. 如果这种electronic chips 同时兼顾

了两种长处,则它应该比 Micro-Mechanics’ chip 更有市场, 这样一来不也削弱了题目的结

论吗?
