Please clarify why b is wrong

Wrong usage of "due to" - should be "because of".

Hello, Could anyone please explain how is C the correct answer? I marked B, but having a re-look I feel it has a dependent statement "mostly due to poaching", which could be weird.
In C, I see "much of that decline" to be too wordy. Please share the explantation.

Thanks,

A. Africa’s population of elephants declined by nearly a third from 2007 to 2014, much of them because of poaching.
many of them, not much of them : countable nouns. WRONG

B. From 2007 to 2014, Africa’s elephant population has declined by nearly a third, mostly due to poaching.
C. Africa’s elephant population declined by nearly a third from 2007 to 2014, much of that decline a result of poaching.
Clearly mentioned in precise manner. CORRECT

D. The population of elephants in Africa declined by 30 percent from 2007 to 2014, many of them because of poaching.
wrong.
E. From 2007 to 2014, the African elephant population had declined by nearly a third, many of them being poached.
wrong.

Please confirm, if in option a, we would have "many" in place of "much", so can it be a correct answer and "them" here refers to africa's population or elephants.

Vkat, I think you're asking if it would be correct if answer choice (A) said the following:

• Africa’s population of elephants declined by nearly a third from 2007 to 2014, many of them because of poaching.

If that indeed is your question, then there's still a problem with the new version. Sure, "many" is an improvement over "much" -- elephants, of course, are countable (...one elephant, two elephants, three elephants...), so you'd need to use "many" instead of "much." It's a step in a better direction.

The sentence would still be flawed, though. The main clause says that the "population of elephants declined". So even if the second part says "many of them because of poaching", I'm not sure that it makes sense: many elephants "declined" because of poaching? I don't think that works: the elephants themselves didn't decline because of poaching, they presumably got killed.

So your change to the sentence would help the grammar, but it wouldn't completely fix the meaning of the sentence in this case.

I hope this helps!

Hi ,

Gramatically C is the best choice that we have here.
But is the meaning conveyed in C same as it is in Question stem(A) ?
I am a bit confused on 'much of that decline a result of poaching'.

Thanks.

Prateekgmat16, in "real life," I think we would understand that (A) is trying to say the same thing as (C). But GMAT SC is all about being strict and literal about the EXACT meaning of the sentence, exactly as they've written it.

Quote:
A. Africa’s population of elephants declined by nearly a third from 2007 to 2014, much of them because of poaching.

"Them" has to refer to a plural noun, and our only option here is "elephants." So the sentence is saying that the elephants declined because of poaching, and that really doesn't make logical sense. The population declined, but you wouldn't say that "elephants declined because of poaching."

So in some sense, sure: the pronoun error in (A) is a grammatical error (and "much" is wrong too, obviously). But in another sense, the pronoun creates a meaning problem. And you'll see that sort of thing pretty often on the GMAT.

I hope this helps!

Hi,
Even why "due to" is wrong here. ??
Even if we replace "due to" with "caused by", the sentence retains the meaning right! ?
Request for Help.
I chose B.

B. From 2007 to 2014, Africa’s elephant population has declined by nearly a third, mostly due to poaching.

Nightmare007, the issue with "due to" is that it can only modify a noun, not a verb. In (B), the phrase "mostly due to poaching" is trying to modify "has declined" -- and that's a verb. So "due to" is wrong in this case. A full thread on "due to" can be found here: https://gmatclub.com/forum/due-to-vs-be ... 40393.html

This isn't really a meaning issue, though: it arguably makes logical sense to say "caused by" or "due to" here, but "due to" is grammatically incorrect. You'll often hear that you can just replace "due to" with "caused by", but that's a little shortcut that doesn't always work for everybody. If you're OK with the grammatical explanation, that's much more reliable. (The shortcut tends to work for native speakers who don't really know anything about English grammar. Since we stopped teaching grammar in the U.S. a couple of generations ago, that shortcut can be great for Americans -- but most people are probably better off without it.)

Hi guys,
I understand the main issues making this option correct, still one thing confuses me - why there is no 'is' between "much of that decline" and "a result of poaching."?
Thanks.

C seems to be the answer

.them incorrectly refers to decline in population in A.
Due to refers to an action of decline in B.
30 percent is incorrect in D.
Past perfect needs to be accompanied by a simple past tebae

Kindly read the explanation given by GMATNINJA so as to know why option B is incorrect.

Why you think MUCH OF THAT DECLINE is incorrect.

I also think the same! Shouldn't there be an "IS" after "much of that decline"??

'much of that decline a result of poaching' is an absolute phrase which modifies the main clause.

the absolute phrases themselves do NOT contain verbs, nor are they connected to the main sentence with a conjunction.

I think so. Tks

E. From 2007 to 2014, the African elephant population had declined by nearly a third, many of them being poached.

VERITAS PREP OFFICIAL SOLUTION:

The primary error in the incorrect answers in this problem is related to pronouns. "Them" is a pronoun that appears in A, D, and E, and in none of those cases is is warranted. Even though the plural "elephants" appears in A and D, and could be seen as an antecedent for "them," "elephants" is not the subject of the sentence (the subject is "population"). This is important because of the context: the population is what declined, so saying "many of them because of..." is providing a reason for that decline - but it wasn't "them" that declined, it was the population. Since the instance of "them" creates a pronoun/meaning error, all three answers are incorrect.

Choice B omits the pronoun error but adds a verb tense error. Since the decline is in the past, with an end date of 2014 as stated, the ongoing "has declined" is an improper verb tense.

Choice C uses a proper simple-past "declined" verb tense and avoids the pronoun error "them," and is therefore correct.
