Hello Everyone!

Let's tackle this question, one issue at a time, and get to the correct choice as quickly as we can! Before we dive in, let's take a quick glance over the original question and options, highlighting any major differences between the options in orange:

Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might, but climatologists have indicated all along that precipitation, storminess, and temperature extremes are likely to have the greatest impact on people.

(A) Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,
(B) Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
(D) The discussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,
(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

After glancing over things quickly, it's clear we have several ways we can attack this question:

1. Discussion / The discussion --> wordiness/meaning
2. have / has --> subject-verb agreement
3. had as a focus / had as its focus / focused --> wordiness
4. to what extent / to what extent it might / to what extent it would be / to what extent that is --> parallelism/wordiness

Whenever you see this many issues to focus on, start with the one you feel most confident in tackling first. That way, you can rule out wrong answers more quickly - and if you're lucky, you won't have to deal with the grammar issues you're less comfortable with!

If you look carefully, we have 3 items on the list that deal with wordiness, and 1 item that deals with subject-verb agreement. Let's start by tackling the subject-verb agreement item (have/has), so we can eliminate 2-3 wrong options right away.

The subject of the sentence is either "Discussion" or "The discussion," both of which are singular subjects that require the singular verb "has" to match. Let's see how each option stacks up:

(A) Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,
(B) Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
(D) The discussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,
(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

We can eliminate options A & D because they don't use proper subject-verb agreement.

Now, let's move on to one of the wordiness topics: has had a focus / had as its focus / focused. The GMAT encourages writers to use concise language whenever possible, and to eliminate any overly wordy phrases they can find. Since the phrases "has had a focus" and "had as its focus" mean exactly the same as simply saying "focused," let's eliminate any remaining options that are overly wordy:

(B) Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

We can eliminate option B because it is overly wordy.

Now we're only left with 2 options. Let's take a closer look at each option to figure out which is the better choice.

(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,

This is CORRECT! It uses concise language wherever possible (Discussion/focused), and the phrase that begins with "whether" is written using parallel formatting (whether Earth would grow warmer and to what extent [Earth would grow warmer]).

(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

This is INCORRECT for a couple reasons. First, it's overly wordy to say "The discussion" when "Discussion" means the same thing. Second, the phrase "whether Earth would grow warmer and the extent that is [Earth would grow warmer]" doesn't make sense because it's not written using parallel formatting.

There have it - option C is the correct choice because it has proper subject-verb agreement, uses concise language, and uses parallel structure!


Don't study for the GMAT. Train for it.

If you have time, I would be so appreciative to learn your thoughts on the following...
For choice E when the expert above mentions "whether Earth would grow warmer and the extent that is [Earth would grow warmer]", why is the expert filling in the "[Earth would grow warmer]" for this "is"? Is the "is" acting as a modal word or a helping verb similar to the words "do" or "did"? Thank you for all of your help.

Dear Experts,

(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

Is (E) wrong just because "is" after the extent is not in appropriate tense?
("is" should be the same tense as would be).
Is there another flaw in (E) ?

• "That" can't possibly work correctly.
It can't be a pronoun (nothing to stand for), nor can it be a relative pronoun ("that is" makes no sense as a modifier).

• "Whether..." and "to what extent..." are objectively more parallel than are "whether..." and a noun ("the extent...").

I'd add to what Ron said that, to convey the meaning conveyed by the correct version, the sentence does need to use the same tense in both the "grow warmer" clause and the "extent" clause since, in a sentence that conveys that meaning, both clauses would be about events in the same time period.

However, as Ron outlined, as written, the (E) version doesn't make sense, with the result that what tense the second clause should use is not clear. In other words, if we consider just the (E) version, we don't really have a solid basis for saying that the tense of the second clause is incorrect. We'd basically be saying that nonsense should have a certain tense.

Let's compare (B) and (C).

(B) Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,

(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,

Both are OK in terms of parallelism specifically.

The problem with (B) is that the meaning conveyed is not clear. In (B) we have "whether Earth would get warmer and what the extent would be."

The (B) version leaves the reader wondering, "The extent of what?" since the sentence does not directly mention anything that there would be an extent of.

In (C), we have the following: "whether Earth would grow warmer and to what extent."

We can understand that to mean "whether Earth would grow warmer and to what extent (Earth would grow warmer)."

In other words, the (C) version provides something that would occur "to what extent."

The term for what we see in (C) is "ellipsis." Ellipsis is leaving out words whose meaning the sentence is understood to convey. Even though the words "Earth would grow warmer" are not written after "extent," they are understood to be conveyed.

"To what extent" is understood to meant "to what extent Earth would grow warmer."

So, the parallelism is between the noun clause "whether Earth would grow warmer" and the understood noun clause "to what extent (Earth would grow warmer)."

Dear Friends,

Here is a detailed explanation to this question-
thanhmaitran
Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might, but climatologists have indicated all along that precipitation, storminess, and temperature extremes are likely to have the greatest impact on people.


(A) Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,

(B) Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,

(C) Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,

(D) The discussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,

(E) The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,


Concepts tested here: Subject-Verb Agreement + Parallelism + Tenses + Awkwardness/Redundancy

• Any elements joined by a conjunction ("and" in this sentence) must be parallel.
• Future actions are conveyed through the simple future tense.
• The simple present tense is used to indicate actions taking place in the current time frame, indicate habitual actions, state universal truths, and convey information that is permanent in nature.

A: This answer choice incorrectly refers to the singular noun "Discussion" with the plural verb "have...had". Further, Option A fails to maintain parallelism between "the possibility of Earth growing warmer" and "to what extent it might"; remember, any elements joined by a conjunction ("and" in this sentence) must be parallel. Additionally, Option A uses the passive voice construction "had as a focus the possibility of Earth growing warmer", leading to awkwardness and redundancy.

B: This answer choice uses the passive voice construction "had as its focus", leading to awkwardness and redundancy.

C: Correct. This answer choice correctly refers to the singular noun "Discussion" with the singular verb "has...focused". Further, Option C correctly maintains parallelism between "whether Earth would grow warmer" and "to what extent". Additionally, Option C avoids the tense error seen in Option E, as it uses the noun phrase "to what extent" rather than a phrase that includes an active verb, such as "is" in Option E. Besides, Option C is free of any awkwardness or redundancy.

D: This answer choice incorrectly refers to the singular noun "Discussion" with the plural verb "have...focused". Further, Option D fails to maintain parallelism between "the possibility of Earth growing warmer" and "to what extent it might"; remember, any elements joined by a conjunction ("and" in this sentence) must be parallel.

E: This answer choice fails to maintain parallelism between "whether Earth would grow warmer" and "the extent that is"; remember, any elements joined by a conjunction ("and" in this sentence) must be parallel. Further, Option E incorrectly uses the simple present tense verb "is" to refer to a hypothetical future event; remember, future actions are conveyed through the simple future tense, and the simple present tense is used to indicate actions taking place in the current time frame, indicate habitual actions, state universal truths, and convey information that is permanent in nature.

Hence, C is the best answer choice.

Thank you for your helpful reply.

What is the rule around using "whether" vs "whether or not"?
I believe "whether or not" is idiomatic, but I have seen the use of "whether" alone as in this official example.

Thank you again.

Hello raaajx,

We hope this finds you well.

To answer your query, here the parallelism is between the phrases "whether Earth would grow warmer" and "to what extent"; both phrase work with the preposition "on" to modify the verb "focused", conveying what topics the discussion focused on.

We hope this helps.
All the best!

Hello woohoo921

"whether or not" is redundant; the message "or not" is inherent in "whether".

Hence, answer choices using "whether or not" are not likely to be correct.

Thanks.

Hello @raaajax,

Hope you are doing well. I will be happy to help you with this one. :)


The elements that are parallel in the list are as follows: Discussion of greenhouse effects has usually focused on

    whether Earth would grow warmer
    (whether Earth would grow warmer) to what extent,

The focus of the discussion is on two points:

1. Will the Earth grow warmer?
2. To what extent will the Earth go warmer?


Choice C is structured in a way to incorporate the two elements in a very precise manner. The list appears grammatically unparallel, but it is a parallel list.


Hope this helps. :)
Thanks.

Hi KarishmaB, can you please help me understand below?

Option C says Discussion of greenhouse effects has usually focused on...

My reasoning for eliminating C was that S-V don't make sense together as how can discussion focus on something, instead shouldnt it be more like option B which says that discussion has had as its focus

Just like a book can talk about ... and a result can suggest ..., a discussion can focus on ...
Nothing wrong with it. Anthropomorphism is the attribution of human characteristics to nonhuman entities, objects, or concepts and is very common.
