Question

Fill in the blank with a suitable preposition
My father takes a nap _______ dinner.
a) with
b) after
c) on
d) at

Answer 1

Hint: A preposition is a word which defines or signifies the position of an object in the sentence. The cat sat on the mat. Where did the cat sit? On the mat. Thus, on is a preposition because it tells us where the cat is sitting. Similarly, answering the question, “When does my father take a nap?” will give you the correct preposition.

Complete answer:
The best way to solve such questions is by placing the prepositions in the sentence and seeing if they are grammatically correct.
Option a says that my father takes a nap with dinner. This means that the father takes a nap and the dinner also takes a nap. The sentence makes no sense and is devoid of logic. So this is the wrong option.
Option b says that my father takes a nap after dinner. This sentence makes sense: that my father takes a nap after he finishes eating dinner.
Option c says that my father takes a nap on dinner which means that my father sleeps on the dinner. This is totally absurd and is most definitely a wrong answer.
Option d says that my father takes a nap at dinner. It implies that my father sleeps when dinner is served. The whole family is eating dinner but my father is taking a nap. This sentence is also incorrect. Therefore, the correct answer is option b.

Note:
On being confused between two or more prepositions, asking a question with the help of the given sentence also helps. For example, to answer the question posed in the hint; “When does my father take a nap?”, the answer will be “After dinner”. Answers like “with dinner”, “on dinner” and “at dinner” are wrong.
