103.

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's 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's 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.

本题答案是E 我想知道为什么不选C呢

each of the following would have to be true EXCEPT means 4 answers are MUST BE TRUE answers while the fifth answer is either must be false or could be false.

In nowhere of the stimulus can you find support for answer choice E. Then E could be false, thus the correct answer in this case.

E completely removes radiation as a threat to chips. Thus it removes the need and the advantage to have the new chip.

C) describes a benefit for computers having such tough chips.

我觉得我对这题理解有问题呢我发现只要题的主题是我陌生的领域我就理不清楚比如什么TECHNOLOGY啊法律啊什么的这该怎么办比如说看到CHIP tiny silicon wafers我就发怵

You do not need to know what a chip wafer is to solve a CR question. To me, it is a CW, a noun.

但我对那些词的敏感度就降低了比如哪些词重要哪些词不重要或者它们的关系
经常读了一遍就跟没读一样！阅读也是一样！

我和你感觉差不多，如果题目都读懂了，感觉脑子里面题目的逻辑就会形象一些，有助于理解。
如果读不懂了，逻辑就顿时在脑子里变成一团浆糊了。
我们还需要多练习

从侧面反映formal chip容易vonerable.也就说明这个新的chip还是能在市场上吃得开的。
