SC Test 3 - Kaplan CD-ROM: usage of idiom "request"

[gurpreetsingh.1982]

Good day all,

In the attached printscreen, you'll see that amongst the answer choices, "D" is identified as the correct answer (though I unfortunately picked picked "E").

I understand that the correct usage of the idiom "request" should be either:-
a)... who request + that + infinitive without to (e.g. I request that test-takers be on time), or
b)... who request + to (e.g. I request test takers to be on time)

Why is option "E" wrong in this question's case (i.e. ... the British Museum continues to rebuff the Greek authorities who request them to return the Parthenon marbles...)

Pls share your thoughts, thanks.

The Greek authorities are requesting that the British Museum return the artifacts, so using the plural pronoun "them" to refer to the singular "British Museum" is incorrect.

Hi Bill,

Thanks for your reply, and well understood!

Hypothetically speaking (and just to make sure I understand this grammar rule correctly), if there was a choice that mentioned "who request it to", would that also be a correct answer?

Of course, I understand that there can only be one answer, just want to be sure I understand the grammar used.
