Question

all Indians must respect each other (correct the error)​

Answer 1

Answer:

All Indians must respect each other.

There is an error of modal in this sentence.

Explanation:

• As we know, the modal verb 'must' is used in reference with obligation and necessity. It is also used to give the sense of law and enforcement.
• Example: We must not smoke in public vehicles.
• Whereas, the modal 'should' is applied when someone is giving an advise or recommendation. It is also used to express an opinion or even an expectation.
• Example: She should have invited her new neighbours.
• In the mentioned sentence, the narrator is expressing an opinion and giving a recommendation.
• Thus, the modal 'must' has to be replaced with 'should'.

Hence, the error is, 'must'.
