Q:

Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. If the given sentence is correct as it is, the answer is ‘No error’. Ignore the errors of punctuation, if any.

The shortest boy of the school/ didn't hesitate to join/ the basketball team which/ was full of tall boys.

A) The shortest boy of the school B) didn't hesitate to join
C) the basketball team which D) was full of tall boys
 
Answer & Explanation Answer: A) The shortest boy of the school

Explanation:

The error lies in the first part of the sentence. After superlative adjectives, majorly two prepositions are used: of and in. We use in with a singular word referring to a place or group. Eg: I am the happiest woman in the world. We use of before plurals, before time periods such as year/month. Eg: Sunday is the best day of the week. Here, in this case, the subject is the 'school', thus, it should be 'in the school'.
