Let us sort out a few things first.

What is the subject of the main clause “both the power of the chips and the electronic devices they drive has vastly increased? Is it ‘both the power’ or ‘the power of both”? This is essential to fix the SV number agreement, the one that is being tested here.

It is wrong to say ‘both the power of the chips and the electronic devices’, because if we are meaning to use power in the plural sense, then it should be ‘both the powers’. On the contrary, the power is meant to be used in singular here, byusibg the term ‘the power of both chips and the devices’ .
The clue therefore is that the right choice will use as subject ‘the power of both’ and as verb ‘has’
Going by this norm, B alone is the winner all the way.


In fact I did not understand the subject :(

subject ---> singular------> verb HAS.........not HAVE........thanks ;)

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 - ruled out - it should be the power of both the chips and the electronic devices- you are comparing 2 nouns(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has - correct
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has - same reason as A
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have - the power of... should be 'has' and not 'have'
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have - same as A

Here we got a parallelism indicator and in between highlighted red portion. First part is a clause but the second one is phrase.. Should these two not be parallel?



I had a same doubt. That was the reason I picked D. Only B and D is close to right, because the position of 'both' to make it parallel and clear. All the others have a misplace 'both'. Any comments?

I was torn between A and B. Went for A.
After reading through I see "the power of" has to come before "both"

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. (GMAT Prep)
1. the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
usage of “ both the power of” is awkward it should be “the power of both X and Y”
2. the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
correct usage of “both x and y” and the word “they” correctly refers to compound subject “the chips and the electronic devices”
3. the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has - usage of “both the power of” is wrong
4. their circuits are more complex, the power of both the chips and the electronic devices they drive have
“their” ambiguity
5. their circuits more complex, both the power of the chips and the electronic devices they drive have
“their” ambiguity

Please EXPLAIN your answer.


I choose B right away.
Had option E been like this -> the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have -> I would have been really confused between B and E.
A general issue with majority of the choices is "both the power of the chips and the electronic devices they drive have vastly increased".
If we scrutinize this fragment, both X(the power of something) and Y(something else) are still parallel and they agree with have. .
So whats wrong with my customized option E?the electronic devices they drive have vastly increased does not make sense.

B it is :the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has

u cannot use "their circuit" as it wud be misleading !! so D and E are out !
B is parallel
C even if u forget logical meaning then C has subject verb disagreement
A is nonsensical in meaning

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
This changes the meaning: "the power of both the chips and the electronic devices" is diffrent from "both the power of the chips and the electronic devices". In A it seems that the power of the chips has increased and the electronic devices(not their power) has increased.
B. the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
CORRECT
C. the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
"are" doesn't maintain the parallelism "lines thinner" and "circuits are more".
D. their circuits are more complex, the power of both the chips and the electronic devices they drive have
"are" doesn't maintain the parallelism "lines thinner" and "circuits are more".
E. their circuits more complex, both the power of the chips and the electronic devices they drive have
Same as A.

Answer is B.

"Their" in Options D and E create ambiguity.
In A,B and C, "The chips circuit" clears ambiguity.

In option C "are more" is not required.

Between A and B, "The power...Both....and... has" is correct.

I believe the original meaning is that the power of the chips and the e-devices have both increased. So, eliminate all choices except for B and D. Between these two, D's part about the chips becoming more complex is awkward and doesn't convey the right meaning. So, choose B.

IMO - B

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 -- Incorrect (electronic devices vastly increased - changes the intent of the sentence.)
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has -- Correct
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has -- Incorrect Same issue as 'A'
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have -- Incorrect - usage of 'are' not parallel. S-V error for 'Power' and 'Have'
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have -- Incorrect Same issue as 'A'

E is the answer
their circuits more complex, both the power of the chips and the electronic devices they drive have

Split is between 1. chips' vs their 2. have vs has

their correctly refers to chips and have refers to plural idiom both x and y.

I choose E

both should be used as "both A and B" like strength of "both lion and tiger". So A, C and E are out.
In D the pronoun their refers to etched lines or chips ? not clear, so out.

Answer is B.

''their'' could refer to either the etched lines or the computer chip. So its not clear. Hence D and E are 100% Out.

As per the Idiom Both X and Y, X and Y must be parallel.

In A and C, we have X = the power of the chips and Y = the electronic devices ; We cannot have Power of something parallel to any device. hence, incorrect.

Only option left out is B.

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

Clause 1: As the etched lines on computer memory chips have become thinner
Clause 2: and the chips’ circuits (have become) more complex
Clause 3: BOTH the power of the chips AND the electronic devices they drive have vastly increased.
On the basis of clause 2, we can easily eliminate C, D, and E.

Now left with choices A and B.
The only difference between the two choices is the positioning of the word ‘power’.
Choice A: the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
Let’s just focus on ‘both the…………’
The verb ‘have’ is plural and is used for power of the chips and the electronics devices.
The marker ‘both…..and….’ shows parallelism and the words/phrases/clauses……must be LOGICALLY parallel.
Here power of the chips is not parallel with the electronic devices.
Hence this choice is INCORRECT.

Choice B.

Please EXPLAIN your answer.
The power is singular that requires singular subject...Both refers chips and ED.thus B is correct choice.

Could you please explain, why the option C is wrong?


C is wrong because of two reasons:

1. The subject "the power of the chips AND the electronic devices they drive " is plural, whereas the verb "has" is singular.

2. "the chips’ circuits are more complex"..... the verb "are" is wrong, should be "have become". In Option B (OA), this correct verb is used, but omitted (correctly) to avoid repitition in parallel items.
