Question

The sentence has four underlined words or phrases. Choose the word or phrase that must be changed for the sentence to be correct.

It is impossible of an alcoholic to drink moderately.

• A. is
• B. of
• C. an
• D. to

Answer 1

The correct option is B of

The sentence given uses the word 'impossible' to describe a alcoholic and his/her drinking habit. The prepositions that are commonly used with 'impossible' is 'for'. The other prepositions that are used after 'impossible' are 'in' and 'to'. We never use 'of' after impossible and so the word 'of' is the incorrect word that needs to be changed to correct the sentence.

Therefore, option B) of is the correct option. The other underlined words in the sentence are correctly used and so option A) is, option C) an and option D) to are incorrect.
