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) Being a rainy day B) we did not feel like going out or doing anything
C) except playing chess in our room. D) No error
 
Answer & Explanation Answer: A) Being a rainy day

Explanation:

The error is in first part. If we start the sentence with being, it means that we were rainy which is incorrect. The sentence indicates that the day was Rainy, and the day will be denoted by ‘It’. So ‘It being a rainy day’ will be the correct idiomatic expression. Otherwise the meaning of the sentence changes.
