My choice A. All other choices distort the meaning of the sentence.

What is known?, the number? or humans?
In this case, the number is known. In the sense, ABC are out.
Between D and E, I go for E.

^ E ^

"humans" in a passive form in A, B and C are not correct to modify the plant and animal species. D sounds awkward too.

Would go for A. E is no good because of passive construction.

Even though it is a little awkward, I think A is right too. E changes the meaning slightly and is passive.

A) Same
B) humans are known as having forced to become extinct
C) humans are known for forcing to become extinct
D) are known that human forced to become extict
E) are known as having been forced to extinction by humans


I would go with A.
E has more degree of passiveness.

"The number of .." should be singular. "E" violates the rule.

answer is "A"

A.

The only other close option is E, and it is passive. Hence A.

The GMAT almost always prefers the active voice.

(A) edges over E.

A) ""

B) humans are known as having forced to become extinct

C) humans are known for forcing to become extinct

D) are known that humans are forced to become extinct

E) are known as having been forced to extinction by humans



E. all others choices change the meaning.

original meaning : The number of plant and animal species is forced to become extinct by humans. should not changed to that "the humans themselves are forced to become extinct."

Well simple one I guess . E .
"The number of plant and animal species that" should be close "forced to extiction" that "human" . Only E gives that opportunity

A,B,C -> humans following 'The number of plant and animal species that that' results in awkward sentence

D -> suggests humans became extinct

E is best.

Well guys and girls, the OA is actually A.

I got this on GMATPrep test 2 right smack in the middle of the verbal section.

Still not sure why...
