Hi Mike,

In your second example of the explanation - I just read a good book which the doctor recommended.
Is the second part a essential clause?
I think it doesn't require a comma before which. Is that right? Or can it be both in this sentence?

Also - in the correct answer for this question, would the answer still be right without "in which"?


Dear Chef,

I'm happy to respond. :-)

Here's the example sentence again.
I just read a good book, which the doctor recommended.
The way in which this sentence is phrased, the clause is presented as a non-vital modifier. Perhaps this would be in a context in which the identity of the book will be supplied otherwise, and the mention of the doctor's recommendation is just a detail. This would be an example of a sentence that is part of longer conversation or flow of information---like most sentence at loose in the real world, but unlike the GMAT SC sentences that are presented in a bizarre clinical isolation. This sentence, while 100% grammatically correct, would not be an appropriate as a GMAT SC sentence.

If we wanted to show that the clause is a vital noun-modifier, we would use "that" rather than "which" and we would drop the comma. For the majority of the time, particularly on the GMAT SC, the word "which" and the presence of the comma go together, signifying a non-vital clause; likewise, the word "that" and the absence of the comma go together, signifying a vital clause.

Choice (E) would be awkward if we simply omitted "in which." As it stands, choice (E) is particularly sophisticated and elegant.

Does all this make sense?

Dear Mike,

Excellent question that stimulates my thinking :-D

I have questions about choices D & E

Choice D

1- Is 'where' correctly used? my analysis is that it is correct because we talk about physical location so no problem. Am I right?

2- Is the phrase 'revolutionary potential innovations' correct or has problems? I think it is in for of [Adjective] + [Adjective] + [Noun], if correct, do I need 'comma' or 'and' between the adjectives?

Choice E

1- As I know 'in which should be followed by clause. Is there some ellipses? I understand the choice as follows:

'in which [the team can use] to conduct research into potentially revolutionary innovations'

Is my analysis correct?

Thanks in advance

Dear Mo2men,

My intelligent friend, how are you? I'm happy to respond. :-)

In Choice (D):
1) the use of "where" is technically correct, as it refers to a physical place; unfortunately, this structure prevents the direct use of the the infinitive of purpose. As a consequence, this version is somewhat more tongue-tied and punchless
2) the hypothetical progressive verb "would be conducting" adds to the wordy and sparkless feel of this choice.
3) On the phrase "revolutionary potential innovations"--first of all, on the level of grammar, this is fine. In English, we often have two adjectives in a row, without a comma and certainly without the word "and."

We certainly can toss in a comma or even the word "and" for emphasis (e.g. "a clear and present danger"), but this is not necessary.
The problem with the phrase is at the level of logic. What is a "potential innovation"? An innovation is something new that makes a difference, so what is something new before it exists? It's unclear whether this has any coherent meaning, and certainly it has a very different meaning from the corresponding phrase in the prompt. This changes the meaning.
There are multiple reasons to reject (D).

In Choice (E):
Yes, there is an ellipsis. You are perfectly correct. Probably the shortest and most elegant ellipsis would be as follows:
The CEO of Laminar Flow gave his R & D team a new $300 million dollar research facility, with cutting-edge technology, in which it is to conduct research into potentially revolutionary innovations.
Many other ellipses would be possible as well, such as the one you suggested.

I got it wrong. Clicked D.

Could you please explain the concept. I actually had no logical approach.

Dear rekhabishop,

I'm happy to respond. :-)

My friend, with all due respect, what you have asked is not an excellent question. It's not an excellent question when your posture is "I understand nothing. The expert needs to tell me everything." The presupposition of such a question is that education something that experts and teachers do to you, and you are just the passive recipient of it. In fact, you are 100% responsible for your learning process. Education is something you do to yourself, by yourself, for yourself, and we experts only can support you in this process. Asking excellent questions is one of the habits of excellence. Here's a blog that discusses it more:
Asking Excellent Questions
Both Chef and Mo2men asked high quality questions here. I will ask you to read that blog, and then I will challenge you to write the highest quality question you can about this SC problem, and I will be happy to answer it.

Does all this makes sense?
Mike :-)
