This one is quite sophisticated. I pick E, and here is why.

A: Almost correct, but the time reference of "vanishing" is fuzzy. It most likely means that they are all in the process of vanishing NOW, which is not what the sentence intends to say.

B: It says "five hundred million" instead of "the five hundred million", and this changes the meaning. "The five hundred million" means that 500 million is ALL the species that have appeared, which is the intended meaning. "Five hundred million" implies that there were more. Compare: "The 20 friggleball players from Elm Street High School were suspended from class" to "Twenty friggleball players from Elm Street High School were suspended from class". In the first sentence, there aren't any other friggleball players. In the second sentence, there are.

C: This almost looks like a poetic and powerful way of saying the sentence, except that the verb is "appeared" instead of "have appeared". "Appeared" means that species appeared in the past, and then STOPPED appearing. "Have appeared" means that species continued to appear up to the present, and still can. The intended meaning is that of "have appeared".

D: "Of them" is wrong, because the sentence already has an "of" phrase that goes with "99 percent".

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

B is close, but it makes it seem like there are more than 500 million species

E for me

A is incorrect because of "vanishing".
C - uses both past and present tense.
D. "Of five hundred..." is awkward.

Between B and E, B uses both past and present tenst. Hence, E should be the answer.

B for me.

The choice is clearly between B and E.
Compared to E, B is concise. Hence B

thanks for all ur replies but the OA is B (source GMAT Paper tests)

good explanation 'oldman' !

i marked E as well esp because of the more clear sentence structure and because of the present perfect "have appeared"

Is there an explanation of that OA? It is a grammatically correct sentence, but it doesn't mean what the original meant. I would have a very hard time buying into it.

I'm not basing my opinion solely on general knowledge either: I have a BA and MA in Linguistics, and that gives me a very thorough understanding of grammar.

Did you consider that the original sentence does not have "the" to start with and also if the modifier that in the original sentence makes me feel that the confusion about the total number is cleared? I some how found E awkward to read

Please note that the OA is (E) and not (B) as mentioned by the OP.

I guess it is better to start sentence with "Nearly 99 percent" instead of "Of the five hundred million different species".....there fore I picked B.

now there are two OA's and which one is right, I don't know....I am guessing and hoping (||ism) that B is right one.

I'm relieved that the OA is E. If it were B, it would be impossible to identify the logic behind that choice.

About the absence of "the" in the original sentence: The sentence still does mean that there were five hundred million species, not more, even though there is no "the". In the other sentences, we need "the" in order to limit the number because of the relative clause after "species". This is a subtle quirk of English grammar, and you'll never see it in a grammar book (unless you have a copy of Quirk, Greenbaum, Leech and Svartvik, and I'm not even sure if THEY describe it). The best way to demonstrate is probably with simpler examples:

"the 20 friggleball players who attend Elm Street High School..." -- means there are only 20 players in the school, and there may be more outside the school

"20 friggleball players who attend Elm Street High School..." -- means there are more than 20 in the world, and there may or may not be more than 20 in the school

"20 friggleball players attend Elm Street High School." -- means there are only 20 players in the school, and there may be more outside the school.
