Identify the grammatical errors in the following sentences and correct them: a) She don’t like tea. b) Each of the boys have gone.

a) She don’t like tea. Error: subject‑verb agreement. ‘She’ is third‑person singular, so the auxiliary must be ‘doesn’t’. Correct: She doesn’t like tea. This violates the rule that a singular subject requires a singular verb.

b) Each of the boys have gone. Error: ‘Each’ takes a singular verb. Correct: Each of the boys has gone. The same rule applies: ‘each’ is always singular.
