Improve the highlighted part of the sentence. Choose ‘No improvement’ as an answer if the sentence is grammatically correct.
The dog chased the ball into the neighbour’s yard.

Correct option is B

The correct answer is (b) No improvement.
The verb “chased” is the past tense of “chase” and correctly matches the simple past structure of the sentence.
Grammatical Rule Used:
· Use simple past tense to describe an action completed in the past.
· Structure: Subject + V2 (past tense of verb) + object
Example:
She opened the door and walked out.
Why other options are incorrect:
· (a) chasing the ball – incorrect tense; makes it a continuous structure, but no auxiliary verb is provided.
· (c) chase the ball – base verb form; incorrect for past event.
· (d) has chasing the ball – grammatically wrong structure; “has” must be followed by “been chasing” in present perfect continuous.
