Q:

Read each sentence to find out whether there is any error in any underlined part and indicate your response in the Answer Sheet against the corresponding letter i.e., (a) or (b) or (c). If you find no error, your response should be indicated as (d).

A) Although we reached his house on time B) he was left
C) for the airport. D) No error
 
Answer & Explanation Answer: B) he was left

Explanation:

The error is in second part. In the given sentence two events occur one after the other. ‘He left’ before ‘we reached’. So, the event that was completed before the occurrence of the next event shall be expressed in past perfect tense. Therefore, the correct form of verb will be “had left”.
