Competitive English Sentence Correction and Error Detection

Question 1

Identify the error in: 'She is one of the students who has passed the exam.'

Accepted Answer

who has passed

Answer

'Who has' should be 'who have' because the antecedent of 'who' is the plural noun 'students'.

Question 2

Identify the error in: 'Each of the boys have done their homework.'

Accepted Answer

have done their homework

Answer

'Each' is singular and requires a singular verb, so it should be 'has done his homework'.

Question 3

Which sentence is grammatically CORRECT?

Accepted Answer

He doesn't know the answer.

Answer

With third-person singular subjects, 'does not' (doesn't) is used with the base form of the verb.

Question 4

Identify the error in: 'Neither the manager nor the employees was present.'

Accepted Answer

was present

Answer

When 'neither…nor' joins a singular and plural noun, the verb agrees with the subject closest to it — 'employees' is plural, so 'were' is correct.

Question 5

Which sentence uses the correct form of the adjective?

Accepted Answer

She is prettier than her sister.

Answer

'Prettier' is already a comparative form, so adding 'more' is redundant and incorrect.
