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.


OA:E


题目的问题是 什么情况下，会对销售产生不利影响


自己选的是D， D的意思 个人理解是：一些电脑会用到的部件，在受到辐射时或受到辐射后将有替代品代替这些部件。    难道意思不是有或者没有M-M公司生产的新设备都无所谓么？？？

如果E成立了，也就是本来的芯片不受辐射威胁，况且它本来速度又快，那Micro研制新芯片有什么意义呢？对吧，楼主~
