Choose the word that means the opposite of the highlighted word in the…

CONCEPT

An antonym question asks for the word whose meaning directly reverses the highlighted word's sense in this exact context, not merely a dissimilar or generically negative word. First pin down the precise sense the highlighted word carries here, then match that sense's exact opposite.

APPLICATION

Here, "profound" describes Rohit's analysis of the poem as showing great depth of thought and insight. The direct opposite of having great depth is lacking depth, i.e. being shallow or surface-level. This is exactly what "superficial" means, so it reverses "profound" in this context.

CROSS-CHECK / CONTRAST

Checking the other options confirms none of them reverse the sense of depth:

• "exacting" means demanding great care, precision, or rigor from effort; it describes strictness or thoroughness of the task, not depth of insight, so it does not oppose "profound".

• "good" is a general positive evaluation of quality; it does not describe depth of thought one way or the other, so it is not an antonym of "profound".

• "mysterious" means puzzling or hard to understand; it concerns clarity, not the depth of an analysis, so it does not reverse "profound" either.

Result: since only one option reverses the "great depth" sense of "profound" into "lacking depth," that option is the correct antonym.
