Question

The children played in the park while their mother______ them.​

Answer 1

The children played in the park while their mother looked after them.

Explanation:

• We have to fill in the blank with appropriate phrasal verb.

• We fill the blank with the phrasal verb "look after", which means to keep under careful scrutiny.

• Since played indicates the sentence being in Simple Past Tense, we use the Past form of "look after", i.e., "looked after".

• The complete sentence becomes: The children played in the park while their mother looked after them.
