IEO Grammar and Sentence Correction

Question 1

Identify the error in the sentence: 'He don't know the answer.'

Accepted Answer

'don't' should be 'doesn't'

Answer

With third-person singular subjects (he, she, it), we use 'doesn't' not 'don't'.

Question 2

Choose the grammatically correct sentence:

Accepted Answer

She is smarter than her sister.

Answer

For one-syllable adjectives, we add '-er' to form the comparative. 'Smarter' is correct; 'more smarter' is a double comparative error.

Question 3

Which sentence uses the correct form of the verb?

Accepted Answer

The news is shocking.

Answer

'News' is an uncountable noun and always takes a singular verb.

Question 4

Find the incorrect sentence:

Accepted Answer

He have gone to school already.

Answer

With third-person singular 'he', the present perfect auxiliary is 'has', not 'have'.

Question 5

Choose the correct sentence:

Accepted Answer

Neither the boys nor the girl is present.

Answer

When using 'neither...nor', the verb agrees with the subject closest to it. The closest subject is 'the girl' (singular), so the verb should be 'is'.
