Question
 I. On December 10, Andhra Pradesh constituted (A)/ a
21 member high level multi-disciplinary committee (B)/ to investigate the disease that was effecting the people of Eluru, (C)/ a city with a population of over four lakh and a hub of agriculture, commerce, aquaculture and export (D). Â II. The sudden outbreak grabbed global attention (A)/ in the first week of December, (B)/ with officials of the World Health Organization (WHO), the State and Central governments, (C)/ and research organizations scrambling to finds out the cause (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- ‘Effecting’ means ‘something that is produced as a result of something’. Disease is ‘affecting’ people, not ‘effecting’ people. II- ‘find out’ should be used, because, the subject organizations are plural. So, ‘scrambling to find out’ is correct.
