Complete the stressed college student's complaint about their thesis by choosing the correct formal relative clause for each blank.

The esteemed professor on whose approval my entire academic future depends just sighed heavily at my first draft. Worse still, the obscure historical texts to which I am referring throughout the essay were mostly found on a dubious fan forum. To top it all off, the study group members with whom I collaborated spent the whole time watching cat videos!

We say "depend on someone's approval." Because the approval belongs to the professor, we use the possessive relative pronoun "whose" combined with the preposition "on."

The verb "refer" takes the preposition "to" (refer to texts). In formal English, the preposition moves before the relative pronoun "which."

You "collaborate with someone." Since the members are people, we use the object pronoun "whom" after the preposition "with."
