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:

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:

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-Mechanics’ 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.

E 谁能解释一下

总结一下题干的信息：说的是MM（不是mm哦）新开发的芯片与传统芯片相比，可以有效抵御辐射，但是缺点在于速度比较慢。

然后问：如果MM的芯片要凭借它在抵御辐射上的明显优势而占据一定的市场份额（通俗一点说就是卖得出去，而不是孤芳自赏；这里隐含了一个条件：即它的优势不能被它的劣势所抵消，甚至颠覆），下面的哪一项不是必要条件？

一个一个看：A，如果拿速度来PK，MM的芯片肯定出局；B，如果同样是12000S的传统芯片，和MM在抵御辐射上并没有差距，则MM有何优势可言；C，更狠，如果芯片根本不要抵御辐射这一能力，则MM根本在自娱自乐，做无用功；D，干扰性很强的一个选项，我的理解是，需要在辐射条件下使用的设备，光芯片能抗辐射还不够，其他部件也要能正常运转，否则就像光有大脑，没有手足一样。

但是有疑问的是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:是然后问：如果MM的芯片要凭借它在抵御辐射上的明显优势而占据一定的市场份额（通俗一点说就是卖得出去，而不是孤芳自赏；这里隐含了一个条件：即它的优势不能被它的劣势所抵消，甚至颠覆），下面的哪一项不是必要条件？

从题目的核心信息来看，我觉得ls的理解也没错；不要被问题的表象迷惑了，回到GMAT CR最基本的类型，实际可以把问题转化为support和无关，会不会好理解一点？呵呵

注意：题目里比较的是芯片里的两种开关：老的不能抗辐射，新的可以。

光芯片抗辐射还不够，其他部件也要能抗辐射，否则芯片没问题，其他部件不能抗辐射，那电脑被辐射后，不是一样罢工了吗？那芯片能否抗辐射都意义不大。

There will be applications in which the speed attainable by an electronic switch is not essential. 说速度不是重要的，也就是说micro的速度劣势不会影响其市场。

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. 说一般的chip的switches没有micro抵御辐射能力强，即强调micro的优势。

There will be applications for computer chips in environments where the chips may have to survive intense radiation. chip将应用在强辐射环境下。即说辐射好的产品，即micro产品将会有市场。

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. chip所用于的devices的其他部件在辐射后仍可以工作，即说只要chip也可以抵御辐射，就是有市场的，即micro有市场。

Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.生产商可以保护chip免受辐射不等于chip自身具有抗辐射能力，无关。

个人理解~~~
