Question
The given sentence is divided into four parts. Read the
given sentence to find out whether there are any grammatical/contextual errors in it. The error if any will be in two parts of the sentence. Select the option which includes those parts from the sentence. If no part in the sentence has an error, then mark 'no error' as your answer. The field-work based approach that the economists (A) / have perfected have revolutionised the (B) / field of development economics and (C) / made it relevantly more in policy making (D).Solution
The error is in part 'B' and 'D' of the sentence. In part 'B' use of 'have'(plural auxiliary verb) is incorrect and needs to be replaced by singular auxiliary verb 'has'( in 'have revolutionised') as the sentence talks about a single approach. In option 'D' use of 'relevantly more' is contextually incorrect and needs to be replaced by 'more relevant' which suggests that field-work based approach has made economics more relevant in policy making. Hence, the answer is option b).
