A. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.

C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.

Pretty sure that E is the answer because it does not repeat "Of" which is repeated in D.

Thanks.

The concept and reasoning behind the correct answer were very well explained by Tommy Wallach, a Manhattan instructor. I feel that he has covered all aspects and there are other quality discussions as well that talk about several different aspects of the problem. So I felt that I didn't need to add anything from my side.

Since i am fast approaching my test date, I left a comment in this thread so that I will know in the future that I have already come across and solved this question. Is that a problem? I'm new to forums and I don't know all the rules. Am I not allowed to post only the answer?

thanks!

Between option (B) and option (E)

Tricky one - not able to figure out any other possible reasons other than one specified above about "the" - definite article.

If that's true, then option (E)

Good remark. It's the absence of "the" that changes the meaning of the sentence in B.

E: conforms to the original sentence that there were only 500M species initially.

Ans: "E"

I would have chosen E but I cannot seem to find a logical explanation to eliminate B other than the fact that it does not contain "have appeared". Can someone clarify if my reasoning is correct..

confused between B and E, like every one else. I think B is very straight forward and concise , hence B.

Yes, that is another good reason that suggests E is better.

have appeared - means the species are still appearing
appeared - means they appeared once and don't appear anymore.
two different meanings.

absence of "the" changes the meaning.

I ate the 10 chocolates someone gave me. -- Here someone gave EXACTLY 10 chocolates.
I ate 10 chocolate someone gave me. -- Someone may have given me more than 10 chocolates and I ate 10 out of that.

Likewise,
Of the five hundred million different species of living creatures -- there are TOTAL 500M different species. No more, no less.
Nearly 99 percent of five hundred million different species of living creatures -- TOTAL may be more than 500M.

I picked B. Can some one explain why article 'The' is required. It should be '500 million', not 'the 500 million'.

I take B,
my reasoning is correct usage of verb tense and usage of participle. we are talking about species that appeared till now. so this whole appearance happened in the past from the author's perspective. additionally the disappearance has started to happen sometimes in the past and it is continuing and its effect is continuing [the disappearance of what that have disappeared is continuing]. so the appearing should have past tense and disappearing should be used as a participle.
because of same reasoning all the other answer choices are wrong.
just my thought...

+1 E

B changes the meaning. It seems to indicate that maybe there are more than 5 hundred million species.

Calling all experts!!!
Agree to all the explanations provided regarding the usage of "the" above. But my question is that shouldn't we stick ourselves to the intended meaning, which says that there were more than five hundred million different species.....?

I go for E.

The problem with B is that "have" is used for 99% of the species. Isn't this a S-V error?

I request some expert to give views on this question : though I agree with E option as correct answer.

Present perfect tense is needed, also option B distorts the original meaning. It states that of the 99% of 5 million different species have disappeared. There could be possibility of having greater number of different species. Whereas, original question states that of the 5 million different 99% have disappeared. This is a definitive quantity.
To keep the meaning intact I will go for option E.

Here is a good post from MGMAT - https://www.manhattanprep.com/gmat/foru ... -t614.html
Also, I guess the answer should be either changed to E or discards, in case the dispute carries on.

Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

A. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
no

B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
"... of five hundred million different species ..." implies that the 500 million creatures in question is a subset of a larger group (think of it as 500 million living creatures out of 501 million living creatures).

C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
ridiculous way of wording this, so very clearly incorrect

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
Of five hundred million... nearly 99 percent of them... is repetitive - the subject-verb agreement is already such that the modifier, vanished, is clearly referencing the subject, 500 million different species

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
to me, this one is correct (I know it doesn't agree with the OA) - Of the 500 million different species indicates that the set in question represents the entire set of species that have lived on earth. The original sentence indicates that ONLY 500 million species of creatures have existed on earth, so the "the" in the first part of the sentence reinforces the assertion that the set in question is the summation of all of the species that have appeared on earth, as opposed to just a subset of them. Additionally, the "nearly 99% have vanished" implicitly modifies the summation of all of the creatures that have appeared on earth, not a subset of them.
