Question

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

Drug abuse have become one of our most serious social problems.

• A. have
• B. one of
• C. most
• D. problems

Answer 1

The correct option is A have

The sentence talks about 'drug abuse' which is a phenomenon that is seen in the world today. Since the sentence talks about one particular phenomenon i.e drug abuse, we need to use 'has' following it. The sentence given uses 'have' which is incorrect. If the sentence mentioned more than one phenomenon, then 'have' would have been correct.

Therefore, the word that needs to be changed for the sentence to be correct is option A) have.

The words given in the other options are correctly used in the given sentence and need not be changed. So, options B, C and D are incorrect options.
