In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select ‘No Error’. No sooner they entered (1)/ than she got up (2)/ and left the room. (3)/ No Error (4)?

Option 1 : 1

The correct answer is '1' i.e. error lies in this part of the sentence.

In part 1 of the sentence, the usage of 'they entered' is incorrect instead, use 'did they entered'

• According to the rule of Grammar, whenever we have used an adverb at the beginning of the sentence we need to use an inversion form of the verb 'entered' is the main verb by writing an auxiliary we can make the inversion. Hence, we need to write 'did they enter
•  Let's see an example-
  • No sooner did I arrive at the station than the train came.

So the correct sentence is- No sooner did they enter than she got up and left the room.
