Question

Fill in the blank with the most appropriate word:
I haven’t seen him ______ he came to dinner with us last week.
A) For
B) Meanwhile
C) Since
D) When
E) While

Answer 1

Hint: Preposition is a word or group of words used before a noun, pronoun or phrase to show direction, time, place, location or spatial relationships and etc. Prepositions are words like in, at, on, and to.

Complete Answer:
Prepositions of spatial relationships are given in the options to fill the blank in the sentence. Examples are: around, below, beside, between, towards, inside under, within, along and etc.
>Option A) For is an incorrect option as it does not form the required meaning in the sentence. For is used when specifying the amount of time i.e. how long. In this particular sentence amount of time is not given. Thus, this is not an appropriate answer.
>Option B) Meanwhile is an incorrect option because meanwhile is a linking adverb which connects and contrasts ideas between two sentences. So this is an incorrect option.
>Option C) Since is a correct answer because since refers to a specific point of time. In this context, since will be used because the sentence denotes a specific time and period i.e. last week. So, this is the correct answer.
>Option D) When is an incorrect option because when is used to refer to a future situation or condition in which we are certain. This is not suitable in the blank. Thus, this is an incorrect answer.
>Option E) While is an incorrect option because while refers to things that are occurring at the same time. In our sentence nothing is occurring at the same time thus does not go with the sentence.

Hence the correct answer is option ‘C’ i.e Since.

Note:In this type of question it is important to understand the meaning of prepositions and their usage according to the sentences. So, we have to use the appropriate answer in the blank so that it fits best.
