Answer 2

Question :

Choose the correct alternative.

He had a break after he ..................................... for two hours. a) was walking b) had been walking c) has walked d) walked

Answer :

He had a break after he had been walking for two hours.

• We use the past perfect continuous form of the verb 'work'.

• Past perfect continuous tense is used to indicate an action which has started at some time in the past and continued till a specific time in the past.

• Here, the action of 'walking' has started at some time in the past and continued till a specific time in the past which could be understood by the verb form "had a break" in the given sentence.

• Hence, the other forms of verb - past continuous (was walking) , present perfect ( has walked ) and simple past (walked) are inappropriate for the blank.
