19.    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


the answer is B.
我不大明白这里的平行，按题目来说，就是“the etched lines on computer memory chips have become thinner”和“the chips’ circuits more complex”平行，但是后面不需要谓语么？“the chips’ circuits （verb）more complex”
thx a lot~

1. As the etched lines on computer memory chips have become thinner and the chips’ circuits (have become)more complex
2.It must be "power of device" increased not "devices".or to say,we should use "the power of both the chips and the electronic devices " which needs "has" afterwards.
