I would vote on (D). (A), (B), and (E) seem to be incorrect from the grammatical viewpoint; (C), on the other hand, doesn't make sense--scientists wouldn't argue about such a problem (in relation to one plant), would they?

Dear Teachers, Gokhan and I are waiting for your opinion.

I'd agree with Nyggus.

A) We have substantial evidence ] "we have evidence whether" is unidiomatic; you would have to say "evidence about whether".

B) Our research had confirmed ] Clash between past perfect and present perfect.

C) Some scientists have argued strongly ] Again, you would have to add "about" before "whether".

D) Sometimes it is difficult to tell ] Fine.

E) There is much difference of opinion among the ] Lacks a noun after "the".

An example is the leaf of the horse chestnut (Aesculus hippocastanum): it looks like several separate leaves on one stem, to the casual observer, but is in fact a compound leaf.

Welcome to UE, by the way, Gokhan!
