Question

Find out which part of the sentence has an error.

• A. His assistants have
• B. And are still doing
• C. Excellent work for the organisation
• D. No error

Hint:

When listing two actions across time, match auxiliary verbs properly: “have done and are doing” (not just “have and are doing”).

Answer 1

The Correct Option is A

Parallel structure.
The phrase “have and are still doing” combines two auxiliaries without clarity. It should be: “have done and are still doing…” to make the structure correct.
