Choose the part of the sentence which has an error.
Our class teacher gave us / an important advice / about sleeping well / the night before the board exam.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → an important advice
The sentence says “an important advice”. This is wrong. We cannot count “advice”. We do not say “one advice” or “two advices”, so it does not take “a” or “an”. It must be important advice or an important piece of advice.
Option 1: Our class teacher gave us — No error.
Option 2: an important advice — Error. “an important advice” should be “important advice”.
Option 3: about sleeping well — No error.
Option 4: the night before the board exam — No error.
Corrected: Our class teacher gave us important advice about sleeping well the night before the board exam.
