Choose the part of the sentence which has an error.
Every one of the girls in the choir / have learnt her part / for the Republic Day assembly / in just one week.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → have learnt her part
The subject is “every one”, which means each single girl. “Every one of” is followed by a plural noun, but the verb stays singular. The words “her part” also show that one girl at a time is meant. So the verb must be has learnt, not “have learnt”.
Option 1: Every one of the girls in the choir — No error. “Every one” is rightly written as two words before “of”.
Option 2: have learnt her part — Error. “have learnt” should be “has learnt”.
Option 3: for the Republic Day assembly — No error.
Option 4: in just one week — No error.
Corrected: Every one of the girls in the choir has learnt her part for the Republic Day assembly in just one week.
