Why 'it' is incorrect?

[Pamela]

Leonidi, them refers to glasses, that's why you need plural personal pronoun them but not it. The whole test consists of a small dialogue, thus, the test questions are closely connected.

[Mkostya]

It's so unfair, why should I assume that the questions are connected?
