In the question given below, the sentence is divided into three parts I, II and III. For each part an alternate statement is also given. You have to determine if a part requires correction, and then mark that as your answer. In politics and public policy, nationalism is a (I)/ doctrine which mission is to protect a nation's right to self-govern and shield (II)/ fellows residents of a state from global economic and social pressures. (III) I. In politics and public policy, nationalism is an II. doctrine the mission of which is to protect a nation's right to self-govern and shield III. fellow residents of a state from global economic and social pressures. Correct Answer Both II and III The correct answer is option 1- Both II and III In part I, 'a' is correct. The use of 'an' in place of 'a' would be erroneous as the word following the article is 'doctrine', which is a word beginning with a consonant. In part II, 'which mission' is grammatically incorrect. It must be replaced with 'the mission of which'. In part III, the adjective 'fellows' must be replaced with its correct form- 'fellow' Thus only parts II and III require correction and should be replaced with their respective alternate statements.
