Verbal Question: The art exhibit, featuring avant-garde sculptures, challenges visitors to ________ their preconceptions about modern art

Can someone please tell me the answer to this question?

Do you know what “avant garde” means? I think that’s what makes this question so tricky.

Also, weigh and examine seem like the only two synonyms among the options

discard and transcend ; subvert and discard seem synonymical to me

What strategy are we using to get to examine and weigh
even discard and transcend have a little overlapping meaning , hence thought it was that

Honestly, I wouldn’t get too in the weeds on 3rd party verbal questions. The sorts of ambiguities you’re mentioning won’t show up on official ETS questions; they either have more clues in the sentence or would have more distinct word choices.
