X helped Y in determining Z

differences between is correct usage

eliminate A B C

left out D E
In D helps is wrong since differences is plural
E wins
IMO E

totally agree with the above explanations
IMO E
Differences is plural hence eliminate C, D for singular noun helps
B changes the meaning by comparing the two ears when the comparison is between how the two ears hear
between A and E "between" is the better choice
moreover A commits a SV error by using determine which is plural for the singular listener

I go for A.

subject = subtle differences
verb = help

"help + bare infinitive" is correct but not "help + (verb+ing)".

E is passive as well.

I take C.
Sound is important here not ears justifying the passiveness

This is confusing one!

Eliminate middleman construction – from in…. listener. This is because the preposition “in” adds the information about “how the listener listen the sound”.

In human hearing, subtle differences … determine the qualities of that sound.

With this only A and C survives

Eliminate C: Passive

OA is A.

Subtle differences implies that qty of diff can be > 2. Therefore Between cant be used. Eliminate D and E.

"...two ears hearing.." is awkward construction , eliminate B.

Between A & C, C has passive voice and SVA problem (subtle diffs-helps), therefore eliminate C.

Ans: A
