Question Stats:
37% (02:18) correct
62% (01:07) wrong based on 7 sessions
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
Please EXPLAIN your answer.

I think I like answer B.
the power is agree with the verb has.
In D and E, the use of their is ambigious.

Please EXPLAIN your answer.
i am also but stuck on this one. I got B too using some other method.
can any one explain why B? why "the chips’ circuits more complex" is not complete?

Please EXPLAIN your answer. i am also but stuck on this one. I got B too using some other method. can any one explain why B? why "the chips’ circuits more complex" is not complete? the chips' circuits more complex is the same in A and B. that's not the issue.
B is correct because "____ vastly increased" at the end of the sentence refers back to "the power" which is singular. even though it's talking about the power of two different things, it has to be "has vastly increased" instead of "have vastly increased"

B is the correct answer. A is also grammatically correct but B is clearer choice.
Thanks

It's B.

thanks
I now see that AC are both not parallel and DE have ambiguous referents.

I go for B.
D and E -> their usage is ambiguous
A and C -> It's the power that increased... not the circuits/devices

I'm sorry, but I'm still very confused here.
I think that answer B sounds incomplete. Should it be the chips’ circuits have become more complex?
Thanx!

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 (the electronic devices they drive have vastly increased=>does not make sense=>OUT)
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has (the power...has=>OK)
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has (both...has=>OUT)
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have (the power....have=>OUT)
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have (the electronic devices they drive have vastly increased=>does not make sense=>OUT)

Please EXPLAIN your answer.
Need to use idiom Both X and Y.
Both the power of the chips and the electronic devices... incorrect usage, should be both the power of X and the power of Y.
Elmin ACE.
I was actually stuck btwn B and D b/c I couldn't figure out whether to use have or has.
however, "the power" requires has. So I choose B.

Do we see anything wrong with A? If not why are we picking a choice (B) that has a different meanings from the original?

A whole lot of discussion but still not clear. Quote: 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 OA is Shoul'nt a sentence have the same tense throughout??Since we already have "HAVE" in the non underlined are..shouldnt the correct answer have "HAVE".Please somebody consolidate the explanation for poor people like me:(

guys this is so not clear..PLEASE help.
both the power of the chips and t he electronic devices they drive have vastly increased. Plural!How can the correct answer be B??

(A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have - subject-verb agreement and idiom (both)
(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 - idiom (both)
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have - not clear lines or chips
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have - not clear lines or chips
B for me
