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"

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!

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.

Is it really correct that it should be "power... has" (both singular) instead of "powers ... have" (both plural), because it refers to two nouns?
I am not a English native speaker.

Thanks a lot (one more to my error log!)

(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

Please someone explain me why "power" is taken as singular... we are here talking about powers of two different items and "have" should have been used here...

++ kudos will be given for the right explanation!!!

Well as you said you were stuck between B and D ..the simple way of eliminating D is looking at the usage of "their circuits" in the beginning. Ambigous since we dont know "their" refers to lines or chips.

hope it helped... I must thank u for clearing my doubt in option A.!!!

cheers!!! :-D

B is the best answer because the singular subject "the power" agrees with the verb "has" but shouldn't the preposition in B "of" be followed by a noun because "of" is not a preposition, according to Spidey notes pg 13, that can be part of a subordinating conjunction?

The correct answer is B because
1) power is singular and hence requires a singular verb "has". This eliminates choices A D and E.
2) "both the power of the chips" implies that the chips have two powers which seems absurd. Correct usage would be "the power of both" (common to both chips and elctronic devices).

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.

A small request to all contributors. It is becoming difficult to follow by looking at captions such as Brutal SC NO, Need help with this SC, SC doubt etc. As a matter of simple procedure, if the first few words of the stimulus are incorporated in the title along with some appropriate tags, it will be very helpful. On the other day, I was contributing to one and the same topic in three different threads, all of them one after another. Moderators, can you please help set some uniform norms!?

You're right. The OA is B.
I spent nine whole minutes on this q because I was trying so hard to sort out those things. Thank you for this clarification Daagh! It helps a lot! 1 kudos coming right up!
