139.    As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased.
(A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have
請問答案為何是b

First eliminate C and D as the "are" does not parallel "have". "have become" was taken out to avoid redundancy. You can put it back.

Second eliminate E, since "their" is not clearly referring to "chips"

Then use your understanding to eliminate A. Also, "...electronic devices ... have increased" is not correct. It can be "number" of devices, or "power" in this question, that has increased. The devices themselves cannot increase.

牛！！，理解的太深刻了。我补充一点我的理解
both the power of the chips and the electronic devices they drive have
both A and B, A, B应该词义，格式平行。
A: the power of the chips.
B: the electronic devices,
power 和electronic不能平行。只有
both the power of the chips and the number of electronic devices,
或者 the power of both the chips and the electronic devices they drive has
提问：
如果是 both power of the chips and the number of chips 谓动是否应该用单数。

应该用复数

但是power, number同属于chips,而且前面没有冠词，不是应该用单数吗，

1, D and E r eliminated as 'their' is wrongly used
2, C is eliminated as 'both a and b ... has' is wrong
3, A is eliminated as the 2 things  compared are not parallel

Mindfree大大跟Snazzy哥哥的分析真是精采啊!!!!佩服!!!

请注意选项中的主语变化

B中是 the power of Both A and B, 主语是 the power,因此用 has

其它是直接 A and B做主语，用have

我想问，既然说D和E中their有歧异：指代lines或者chips不明确，

那正确答案B中的they大家又怎么判断是清晰指代chips的呢？理论上不是也可以lines、chips、circuits甚至是lines+circuits（因为这两样东西加起来才是完整的主语）呢？

谢谢大家一起讨论下！
