i dont have an oa. but here are my thoughts

a)-ing is not the intention of the sentence
c)passive
d)of them is wordy
b)very convoluted. its like saying nearly 50% of the 500 students of farifield high school are retarded. Or would you say "of the 500 students of fairfield high school, nearly 50% are retarded.

which is why i choose e

E.

D appears right at first but should have ended with "nearly 99 percent have vanished. "

should be B.

99% is singular so "have"s in D and E are wrong.

E keeps true to the form that was expressed in the question.

99% of~ species ---> plural is perfectly fine. Additionally, B omits the essential "the"

Choose (E) and click confirm.

but we observe the same error in B, the sentence refers "have" to the 99%.

In E, the "have" refers to the 500 million- thats what I think.

would click on E and confirm.

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

I might be wrong here but let me try..
B would sound better if it was written as

Nearly 99 percent of the five hundered million different species of living creates that have appeared on Earth have vanished.

B.

I chose B because I was not very happy with E (red part).

I think we need ending part like "that have 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.
ruled out compeltely.

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
verbose, "of them" can be avoided as sentence begins with "of"

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

It's B or E. I am not 100% sure, but would choose E for simplicity.

B is awkward. Sounds like everyone is going to die, 99 percent already gone

Yes its between B and E.

B looks like just a formal statement.
E - emphasizes on the 99%, which is important here.

Just using my ear, i am picking E. But, would like to know exact error with B.

I think the reason B is wrong is the same as why D is wrong. At least by 1st look.

Both B and D state "of 500 million" It should read "of the 500 million"

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

A. Five species of creatures have appeared on Earth, nearly 50 percent of them vanishing.
B. Nearly 50 percent of five species of creatures that appeared on Earth have vanished.
C. Vanished are nearly 50 percent of the five species of creatures that appeared on Earth.
D. Of five species of creatures that have appeared on Earth, nearly 50 percent of them have vanished.
E. Of the five species of creatures that have appeared on Earth, nearly 50 percent have vanished.

We have established that A and C are incorrect.
So I've taken out the hard stuff to try to simplify this question. (Please note "To try to" rather than "to try and")

I would say that B is incorrect, because the tenses are not consistent. "Appeared" goes with "vanished" (no 'have').

In D, "Of five" is incorrect. When you are identifying a subset of the population in the subsequent clause, the "five" actually serves the same function as "group" or "set", but has a numerical value.
So you would say, "Of the class of children we brought to the park, 50% were covered in dirt when they returned home".

In E, the two 'Of' are unrelated. They just happen to be the same word, meaning different things. Similar to the example of that that.
Also E fixes the issue from B, where the tenses were different. These are both past.

These are jsut my thoughts, I'd welcome some feedback. I've often found it useful to identify the "filler" in these SC questions and then work with the most simplistic version of the phrase - obviously needs to be done carefully to avoid changing the meaning. Just delete all adjectives.

P.s. Also I think that this sentence is very unclear anyway - it would be much better is we knew whether the species all appeared at the same time. A indicates that they appeared over a period of time, whereas B indicates that the species appeared all at once.
