But B is missing a word "the".

Does indeed sounds strange without a 'the', but clarity of the sentence is still maintained even without the word.

No, "the" must not be ommitted, otherwise it suggests that there might be more than 5 hundred mil creatures in the earth.

Example:

"The ten of us that take this class went to dinner together yesterday." means there are only ten of us that take this class and we all went to dinner together.
"Ten of us that take this class went to dinner together yesterday." means there might be other students that take this class who did not went to dinner with us.

its between D and E. could be E.
What's the difference between "of 500" and "of the 500"?

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.

I prefer B unless someone refutes it.
Both D & E use have twice which isn't good.

of the 500 is correct, where as, of 500 is incorect.
I go with E.

We can use "have" twice in the sentence if required.

Following is an OE from OG, which made me choose B

Recognize the error being tested:
Verbs: When there are two or more time frames in a sentence be alert for verb errors being tested. In this case there are the time periods where the members had the minutes and the period where they 'were part of the culture.'

Decide On a Fix:
The rule for this form of the Verb error is that the time frames must be made clear through the use of words that indicate time and/or through use of the have + verb form with one of the verbs.

Because the have + verb form is used with the verb 'led' the other verb should not use this form.

Thus, E would have been better this way:

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

However in B, Nearly 99 percent of (the) five hundred million different species, would have been better

E for me.

Sonaketu, The 500M species have appeared over time. Shouldn't we use "have" (present perfect) to indicate that it was a continuous process.

E it is
B's multiple prepositional structure is wrong. For instance, instead of saying "100 of X of Y that...", one should simplify things down to "100 of THE X of Y that...". This makes the sentence much more simple by removing degrees of reference.

D has the same problem as B but furthermore, we are not sure whether personal pronoun "them" refers to "species" or "creatures" and it also intrudes the flow of the sentence. The appositive form in E, at the end and without the superfluous "them", makes for a much better sentence flow.

I would've gone for B, but I guess "the" makes a difference.

Paul, do you think using have appeared .. have vanished is correct?

I find both B & E to have flaws, guess we need to find the smaller one.

B sounds better.

The clause "99 percent have vanished" doesn't seem to be proper. is it not preferable to have 99 percent of something in one clause?

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

Amazing how much debate this and similar questions have sparked so far. I'm sure the debate will continue.

(E) is fine, no problems.
The Past perfect have appeared / have vanished is the correct verb tense. One use of past perfect is to describe action that began in the past, and continues today. May help to imagine the words "so far" at the end of the clause to see if it makes sense. (I have eaten breakfast tacos every morning this year, so far.)

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

YES that makes perfect sense. The process of new species formation began in the past (or we wouldn't be here to discuss it) and still continues today (it is assumed), and for sure the process of species extiction began in the past (e.g., dinosaurs) and continues today (save the whales). And so, past perfect is clearly correct.

AND there is nothing wrong with placing the prepositional phrase "Of the 500 million species" before the subject "nearly 99 percent". It is clear what 99% is referring to, and that just gives some stylistic variety; a writer might do something like that because it sounds good to the ear, or to emphasize one part of the sentence, or to keep close together the subject and verb.

The author of this sentence, for example, might've wanted to go for the throat-grabbing effect of saying "nearly 99% have vanished!!!" . Which is kind of lost if you separate the subject (99 percent) and the verb (have vanished) with a rambling, 15-word prepositional phrase.

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

Answer choice (D) is similar to correct answer (E), so why is (D) wrong? Because "of them" is redundant.

Those of you looking for the words "99 percent of x" are correct, in that 99 percent must be modified by a prepositional phrase: 99 percent of something. (but the sentence can be written in different order)

Unfortunately (D) gives you not one, but two somethings :

99 percent of them
99 percent of five hundred million different species...

So which is it? Because "five hundred million different species" is preceded by of, it is a prepostional phrase suffcient to modify "99 percent". The pronoun them is not needed, and in fact is an unacceptable redundancy.
