Question

Choose the appropriate preposition and fill in the blank:

We had an interesting discussion _____ the problem but we did not reach a conclusion.

• A. of
• B. for
• C. after
• D. about

Answer 1

Answer: (D)

about

The given sentence indicates a connection between the discussion and the problem. Therefore 'about' is the suitable answer, since 'about' is used to construct a connection between two different objects. Thus option D is correct. On the other hand 'of' is used to depict any belonging or any relation. Hence option A is incorrect. The preposition 'for' is used to denote any cause or reason, while 'after' is used to mean something next to. Since the sentence constructs between two objects, option B and C are incorrect.

The completed sentence thus becomes: We had an interesting discussion about the problem but we did not reach a conclusion.
