The subject of the sentence is ‘group’, so the correct verb is ‘projects’ … this eliminates A, B, and C.

Also, the average is a fixed number. It is not a range.

Imagine someone average GMAT score is 730 (in multiple attempts).

We can say: His average score is between 720 and 740. CORRECT

But we can’t say: His average score is from 720 to 740. INCORRECT

Same deal here: So D is wrong.

Correct: E

One thing that I noticed about GMAT SC correction is that you very often have 3 answer choices with something in common and 2 answer choices with something in common.

The answer is E

The subject here is" An international group" which is singular so we have to use a singular verb .
Note that a noun in the prepositional phrase can not act as the subject of the sentence here "more that 2,000 scientists " is in prepositional phrase so can not be the subject of the sentence .
Next thing is the use of between and from
One point to note here is that the average will be a certain number it can not be spread across a range so that value has to come between some numbers , so here in this sentence we have to use between therefore D is rejected outright .


There is meaning error as well in D this choice suggest that the international group projects global warming to average rather all they do is project the average of global warming .

I want to summarize
1. collective noun, by defaut, will take singular . this means we can see on gmat sc some cases, in which collective noun take plural.
2. something is project to do
is good pattern. but we do not use
project something to do . this point is from oxford dictionary
3. average is a point and, so, can not go with from...to. "average" must go with "between a... b"

hard problem.

For Singular Subject we need Singular verb so A,B and C are out.

Between D and E, E is the right choice. D distorts the meaning of the original sentence. Original sentence doesn't talk about the average value but it talks about range value.

well, d has two problems, at least:
- 'projects X to do Y' is unidiomatic. (you can just say 'projects NOUN', as is done in choice e, or you can say something like 'projects that X will do Y').
- an average is a single data point, so there's no such thing as 'averag[ing] from 1.8 to 6.3'. on the other hand, it's quite possible for a single data point to fall between two given values.

i've seen 'of between' in this sense before - think of the phrase 'between 1.8 and 6.3' as standing for a single number, and parse the sentence accordingly (it reads as if it said 'average g.w. of 5 degrees', for instance) - so, if the original poster has copied the problem correctly, we now know that the gmat accepts that construction.

Hi ugimba,

Thank you for your question. Let's start by looking at the most obvious difference between each answer: project vs. projects.

The subject of the sentence is "An international group," which is a singular subject that needs a singular verb to match. The verb "project" is a plural verb, so we should rule out any answers that use "project": A, B, & C.

Now we're left with answers D & E. While they look similar, they mean different things:

(D) projects global warming to average from 1.8 to
This means that the temperature of the Earth will be somewhere between 1.8 and 6.3 degrees Fahrenheit by the year 2000. If this is true, we're not talking about global warming - it's going to be cold! The way this is written changes the meaning, so it is incorrect.

(E) projects an average global warming of between 1.8 and
This is the correct answer because it uses proper subject-verb agreement, and it keeps the intended meaning. This answer says that Earth will warm between 1.8 and 6.3 degrees MORE than what it already is, which is what the writer intended to say.

In the end, we're left with the correct answer: E.
