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 swithces and the chip will contain only 12,000 switches.

For there to be a market for Micro-Mechanics's chip as a result of the apparent advantage described above, each of the folowing 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 eletronic computer chips against exposure to intense radiation, where this protection is necessary.

请问做题思路是怎样的?谢谢!

答案:E

这个其实是一个削弱题,选择削弱MM CHIP的选项

题意:
Electronic computer chips是由一堆不能withstand intense radiation的switches组成的
MM这个公司想要改进。新的switches可以invulnerable to radiation

问:
以下那条可以使MM的switches有市场?
其实就是选支持MM的

A。有些电器开启时间不是很重要(对 不重要么,开关慢点就慢点,而MM得特点就是慢)
B. 同样12000个switches.  Electronic chip 要比MM的CHIP更vulnerable to radiation
C。D.无关

E。制造商可以保护 eletronic computer chips 不受 intense radiation伤害。。
  (这个肯定不是向着MM的 CHIP的。。因为制造商的保护,把MM CHIP的优点削弱了)
