Question

Fill in the blank with the suitable conjunction from the options given.
The children have been playing video games on the internet _________ four hours.

• A. Since
• B. When
• C. For
• D. Then

Answer 1

The correct option is C For

The correct answer to this question is option C as 'for' is used to talk about a period of time continuing up to the present or to refer to a length of time as mentioned in the sentence.

Option A is incorrect as 'since' is used to refer to a starting point of an event that is continuing up to the moment of speaking.

We use 'when' as a conjunction to mean 'at the time that'. It is also important to note that the clause with 'when' is a subordinating clause and needs a main clause to complete its meaning. Hence option B is incorrect.

Option D, 'then', which is used to mean 'in that case' or 'after that', would be grammatically incorrect if used in the sentence.
