Mr. Patel was a key member (A)/ of the Biden-Harris campaign (B)/ and was currently a senior spokesperson (C)/ for the Biden-Harris presidential Inaugural Committee (D). Directions: In each of the questions, two sentences are given which are divided into four parts (A), (B), (C) and (D). Both the sentences may have errors in one of the four parts or may not have any error at all. You have to find out the parts containing error and mark that alternative as the answer.Solution
I- While speaking about a person, ‘who’ should be used instead of ‘which’. So the fragment would be ‘Vedant Patel, who was appointed…’. II- Since we are talking about a person’s current position, ‘is currently’ is correct and not ‘was currently’.
