Between A and E, I will go for A because it restates chips` to avoid ambiguity.

Why not B?

This option also has Chips which will avoid the ambiguity. Apart from that it is more clear that the new design increases the power of both the chips and the devices.

Answer is A.

'both the power of the chips and the electronic devices they drive' cannont go with 'has' so B and C are ruled out

D and E have no chance

sorry answer is B because A changes the meaning. has Vs have is the trick. It is power of both so B is the answer

"their" in D and E is ambiguous and may make reader think that "their" refers to "the etched lines".
as the sentence uses "the power" instead of " both the power of the chips and the power of the electronic devices" or instead of "the powers"...."the power" must be singular here. B is correct.

OA is indeed B!
Both is used to denote the power of 2 things and not used with reference to power and something else thats not present! As power is singular, we need a has and not a have!

B is right because it uses the s-v agreement properly. the power ..... is singular here and it needs has.
B does the job.

Hi,

Why do you think it modifies the line and not chips as "their" is closer to the pronoun ? Please explain


IMO- it should be E , the pronoun their is refrent to the chips !

This one was tough! I wouldn't have missed it if I would have focused on the "has vs. have" split. That would have eliminated all but B and C with <b>B</b> coming out the clear winner.

Why is A wrong!


both the power of the chips and the electronic devices they drive have


I dont see any errors in this statement ---

Chips become thinner

The Power of the chips increased --Sounds logical

the electronic devices they drive - sounds logical

Conjunctions "And" joins so we have plural verb "have"

Any experts--ur comments welcome

E is perfect.

(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[/quote] - Correct

Guess!!

They refer to Memory Chips!


Thanks Ozmba2006 - but still confusing

Memory chips driver the power of the ( memory )chips and they drive the power of the electronic devices !!

I dont agree with the OA. However re-reading the question and taking the OF phrases out......B seems to look right. We just got to be careful with those OF statements. They can safely be removed most of the times.

Thanks Cooper -- read a lot of forums trying to figure out this SC..and this is my conclusion.

Plugging in B below:

As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has vastly increased.

They - refer to the memory chips is correct because the power of the electronic devices that the memory chips drive has vastly increased.

The power of the chips and the elec. devices that the chips drive has vastly increased.

If the chips were becoming thinner - then the choice A is wrong because the electronic devices cannot vastly increase.

Hope I am right....
