Despite no proof of salmons having olfactory memory, studies have shown that the fish would return to the exact spot where they were born to spawn.

A. Despite no proof of salmons having olfactory memory, studies have shown that the fish would return to the exact spot where they were born to spawn.
proof requires a clause starting with THAT. In the choice HAVING... Modifies the saloman.
Since there is a clause, although is correct instead of despite
WOULD is wrong here as the event of saloman fish going back is still going on


B. Despite no salmons having been proved to be having olfactory memory, studies have shown that the fish return to the exact spot of their birth to spawn.
the phrase after Despite is awkward

C. Although salmons have not been proved to have olfactory memory, fish returning to the exact spot where they were born to spawn has been shown by studies.
Awkward.

D. Although it has not been proved that salmons have olfactory memory, studies have shown that the fish return to the exact spot where they were born to spawn.
Although is used and proof is followed by a clause. Would return is changed to simple present ' return'.... correct

E. Although salmon has not been proved to have olfactory memory, studies have shown that the fish returns to the exact spot where it was born to spawn.
we are talking of all salmons. The dependent clause after although is not correct

D

the fish returns to the exact spot where it was born to spawn..... here it refers to fish which is singular, which is correct. in rest of the options plural pronoun is used for fish.
I think E is correct.
correct me if i am wrong

When we talk of plural of fish of same species, fish itself is plural...

here we are talking of entire species of saloman, so we are talking of all fish of that species and FISH is correct to show plural.

chetan2u Does "it" refers to the assertion "salmons have olfactory memory" in the above sentence and is it the correct usage ? Do we refer to these kind of facts as always singular ?

Thank You.

[quote="aragonn"]Despite no proof of salmons having olfactory memory, studies have shown that the fish would return to the exact spot where they were born to spawn.


A. Despite no proof of salmons having olfactory memory, studies have shown that the fish would return to the exact spot where they were born to spawn.

B. Despite no salmons having been proved to be having olfactory memory, studies have shown that the fish return to the exact spot of their birth to spawn.

C. Although salmons have not been proved to have olfactory memory, fish returning to the exact spot where they were born to spawn has been shown by studies.

D. Although it has not been proved that salmons have olfactory memory, studies have shown that the fish return to the exact spot where they were born to spawn.

E. Although salmon has not been proved to have olfactory memory, studies have shown that the fish returns to the exact spot where it was born to spawn.


D is the correct answer.
It uses proper conjunction "Although", has correct verb form "return" as the intended meaning is for all salmons not a single salmon.

Here are other markers to identify errors on this question.

A - "Proof of salmons" is ambiguous in meaning.

B - The phrase "of their birth to spawn" - This changes the meaning of the sentence.

C - Unnecessary usage of the passive construction in the phrase "fish returning to the exact spot where they were born to spawn has been shown by studies".

D - OA

E - Talks about "salmon" where the sentence is supposed to talk about salmons in general.

Hope that helps.
