Read the sentence to find out whether there is any error in it or not. The error, if any, will be in one part of the sentence. The number of that part (which has the error) is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.
This is the same (1)/ pair of shoes which (2)/ I had seen at this (3)/ shop last year. (4)/ No error (5)
Correct option - 2
Whenever word 'same' is mentioned in the sentence. Don't take any relative pronoun except that. So, replace which with that in 2nd part. So, option 2 is the correct answer.
Correct sentence - This is the same pair of shoes that I had seen at this shop last year.
