Question

Choose the correct option to fill in the blank:

Sarah ______ (live) in London _______ 1985.

(Sarah is still living there.)

• A. has lived ... for
• B. has been living ... since
• C. has lived ... since
• D. has been living ... for

Answer 1

The correct option is B has been living ... since

The present perfect continuous tense (also known as the present perfect progressive tense) shows that something started in the past and is continuing in the present time. Here the action of living is continuing to the present. The present perfect continuous is formed using the construction has/have been + the present participle (root + -ing). 'Since' is a preposition that indicates the point of time from which something begins, here, 1985, whereas 'for' indicates duration of time. Hence, Option B is correct.

The rest of the options do not express this condition. They mention actions that have just completed (Options A and C).

(Option D) 'For' does not indicate a particular point in time '1985' but 'since' does.

Hence these options are incorrect.
