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-Mechanic's chip as a result of the apparent advantage described above, each of the following would have to be true EXCEPT:


There will be applications in which the speed attainable by an electronic switch is not essential.

Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanic's chip will be.

There will be applications for computer chips in environments where the chips may have to survive intense radiation.

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.

Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.

考题讲解

情景:

推理:从原文信息中,我们可以找到新的部件的优势在于
(1) 抗辐射
我们也可以找到新部件的劣势在于:
(1) 速度慢
(2) 只能含有12000个转换器
题目就是要求我们找到四个选项是让这种新产品有市场的。由于本题不需要我们评估推理文段,所以其属于:必然性推理

选题方式:

选项分析:

A选项:有些应用上的电子转换器的速度并不是必需品。本选项说明有些应用可以忍受速度慢,显然在这些应用上新产品是有市场的。

B选项:只有12000个电子转换器的电子芯片比Micro-Mechanics的电子芯片更难以承受强辐射。本选项说的是新产品的优势。只有当含有同样数量的电子转换器的两者相比较,新产品抗辐射更强,新产品才有市场,否则我们直接减少以前的老芯片含有的电子转换器数量即可。

C选项:有些对电脑芯片的应用是要在芯片必须承受辐射的环境下运行的。本选项给出了新产品优势可以应用的领域。

D选项:
一些应用电脑芯片的设备含有其他的一些有能力在辐射暴露的环境下工作的元件。如果所有设备的其他元件都不能在辐射下工作,那么只有电脑芯片一个可以工作也没用,这种新产品就将没有市场。

E选项:
Correct. 当保护是必须的时候,制造商有能力保护电脑芯片不受到辐射的伤害。如果制造商有能力通过某种手段来保护电子芯片不受辐射影响的话,那么新型的抗辐射的芯片就没有市场,因为大家可以采取别的手段来抵消掉新芯片的优势。
