Question

we have been using our television ------------ ten years? ( since, for, from, during )​

Answer 1

Here is the correct answer:

We have been using our television for ten years.

Explanation:

'For' should be used here in place of 'since' because 'for' is used for duration of time; and 'since is used to refer to the beginning of an action until the action continued.

We use the present perfect continuous for an action over a period of time leading up to specific time. We also use 'for' and 'since' with the stated time period or duration.
