Extinction

[parallel_chase]

The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five-times greater than when the use of DDT was sharply restricted in the early 1970’s

(A) extinction; its numbers are now five times greater than
(B) extinction; its numbers are now five times more than
(C) extinction, their numbers now fivefold what they were
(D) extinction, now with fivefold the numbers they had
(E) extinction, now with numbers five times greater than

OA to follow.

[karmayogi]

IMO A.

'The gyrfalcon' is singular. C(their) and D (they) ruled out.
E: numbers of what? ruled out.

Between A & B or between greater than & more than:
"5 times greater than" is correct, hence IMO A.

Between A & B or between greater than & more than:
"5 times greater than" is correct.

Can you pls elucidate on this a little more. I am confused between greater than and more than.

Yes OA is A.

Thanks.

imo:A

A) extinction; its numbers are now five times greater than

uses singular pronoun correctly "its" for antecedent gyrfalcon,
also," its numbers" a countable thing so "greater than"

(B) extinction; its numbers are now five times more than

(C) extinction, their numbers now fivefold what they were

(D) extinction, now with fivefold the numbers they had

(E) extinction, now with numbers five times greater than

Both D and E uses "now with" to introduce a clause which confusingly modifies extinction and which tried to join the two clauses..

A new clause with present tense verb should be used...

thanks.
i hope this helps.

IMO A.

I second karam yogi.

The greater than is correct as numbers are countable.

I found this post by Ron for the same question.

He gives clear and concise reasons for using greater than VS more than.
