Question

Fill in the blank with a suitable preposition:
Mary thinks that David is _______ love __________ her.

• A. In / with
• B. On / with
• C. In / at
• D. At / in

Answer 1

The correct option is A In / with

We can determine the required answer with the help of logic and by eliminating the incorrect answer. In, on and at indicates position. In denotes a position inside or within something. Thus 'in' fulfills the first blank of the given sentence.

Options B and D can be thus eliminated as incorrect answer.

'With' indicates means, possession, contents, relationship, for and against. The second part of the sentence indicates a relationship. With fulfills the second blank of the given sentence. Thus option A is the correct answer.
