Q:

Read each sentence to find out whether there is any error in any underlined part and indicate your response in the Answer Sheet against the corresponding letter i.e., (a) or (b) or (c). If you find no error, your response should be indicated as (d).

A) His friends feel that B) he will be suspended
C) unless he does not report for duty immediately D) No error
 
Answer & Explanation Answer: C) unless he does not report for duty immediately

Explanation:

The error is in third part. By using ‘not’ after ‘unless’, both the negatives cancel each other. So, the correct usage will be ‘unless he reports for duty immediately’. Since “unless” is negative it should be
followed by affirmation, like “unless he reports for duty”. Incase “unless” was absent, we could have written “if he does not report” and expressed the same meaning.

A) I prefer B) this book
C) than that one. D) No error
 
Answer & Explanation Answer: C) than that one.

Explanation:

‘prefer’ is a verb that is always followed by the preposition ‘to’ expressing choice or preference over something else. In this case choice of ‘this book’ over the ‘other’ one. ‘Than’ is used for comparing to options, ‘prefer to’ expresses choice. Correct expression will be ‘to that one’.
