Question

_____ until midnight last night.
(A) I have read
(B) I have been reading
(C) I am reading
(D) I was reading

Answer 1

(B) I have been reading

=> I have been reading until midnight last night

Answer 2

I have been reading until last midnight. (option B)

• Here the action is still going on. So we should use the present perfect continuous tense.
• This tense describes an action that started in the past and is still going on.
• The construction of present perfect continuous tense "has/have been+present participle(-ing)"
• The other options "I have read", "I am reading", and "I was reading" is not in present perfect continuous tense as suitable for the sentence.
• Therefore option B is the correct answer.
