标题: 问prep-103(GWD 27-Q2)
103. (25386-!-item-!-188;#058&001420) (GWD 27-Q2)

Electroniccomputer chips made of tiny silicon wafers now regularly contain millions ofelectronic switches. Unfortunately,electronic switches that are this small cannot withstand intenseradiation. Micro-Mechanics plans toproduce a chip that, because it uses only microscopic mechanical switches, willbe invulnerable to radiation damage. Theswitches will, however, be slower than electronic switches and the chip willcontain only 12,000 switches.
Forthere to be a market for Micro-Mechanics's chip as a result of the apparentadvantage described above, each of the following would have to be true EXCEPT:
A.There will be applications in which the speed attainable by an electronicswitch is not essential.
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.

正确选项是E，我选的是A，不知道A为什么不对。
原文说这种新的switches相对slow，那如果市场认可不就是说明速度快不是必要的吗？
请NN指点，谢谢啦~~~~!!!!

这个是结论题。公司用了新s但是速度慢了。辐射低了，证明有市场是辐射低比速度慢更重要。
我纠结在B啊，B说只有12000的比M的心s要更容易受辐射所害。可是它不是说新S就是只有12000么。。。。。。

THX for your answer!
原文如下：Electroniccomputer chips made of tiny silicon wafers now regularly contain millions ofelectronic switches. Unfortunately,electronic switches that are this small cannot withstand intenseradiation. Micro-Mechanics plans toproduce a chip that, because it uses only microscopic mechanical switches, willbe invulnerable to radiation damage. Theswitches will, however, be slower than electronic switches and the chip willcontain only 12,000 switches.
Forthere to be a market for Micro-Mechanics's chip as a result of the apparentadvantage 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.
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~

那也不能推出12000容易辐射啊。如果12000是新的不就不是啦

不能选A,A是提干给我们可以得出的结论,这种芯片虽然慢,但是可以抗辐射
A项说在一些不需要告诉的情况下应用是非常符合题目的,可以体现APPARENT ADVANTAGE

B也不能够选,这个不是谈数量的问题,这个是谈芯片性质的问题
原芯片无论数量多少抗辐射能力都低于M型的芯片

来问问D选项，ms是个无关项啊，哪里看出来和m芯片的优点相关了呢

D的意思说芯片所在范围其他的部分在被辐射前后，有替代部分可以工作。这样整个电脑即便被辐射了也还是可以工资的。因为要是只有芯片防辐射，那被辐射后其他部件不能用了那电脑也还是用不了。所以D是有必要的

这题纠结很久，终于想明白了。

真狡猾啊。。。首先很容易证明前四项都是很容易排除的：A说对速度的要求不是必须的，可以接受；B个人觉得是无关选项；C说需要对抗高辐射的硬件；D说除了芯片，其他零部件也要能防辐射。

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。。。

正常人看到制造商能够抵抗辐射的时候，应该都会潜意识想到默认指的是在有机械芯片的情况下吧，太狡猾了。。。过分。。。

终于明晰了！
