Find out which part of the sentence has an error. If there is no error, choose ‘No error’.
Physics was never easy for Aarav / until the new teacher / began showing simple experiments in class.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → No error
The part that may look wrong is “Physics was”. The word “physics” ends in -s and looks plural. But it is the name of one subject. Names of subjects such as physics, economics and mathematics take a singular verb. So “Physics was” is right, and the sentence has no error.
Option 1: Physics was never easy for Aarav — No error. “Physics” is one subject, so the singular “was” is right.
Option 2: until the new teacher — No error. “The” is right because one particular teacher is meant.
Option 3: began showing simple experiments in class — No error. “Began” is in the past like “was”, and “began showing” is a correct form.
