SECTIONIV

This section contains 2 questions. Each question contains statements given in two columns,

which have to be matched. The statements in Column Iare labelled A, B, Cand D, while the

statements in Column IIare labelled 1, 2, 3, 4 and 5. Any given statement in Column I

can

have correct matching with ONE OR MORE statement(s) in Column II. The appropriatebubbles corresponding to the answers to these questions have to be darkened as illustrated in

the following example:

If the correct matches are A 1, 4 and 5; B 2 and 3; C 1 and 2; and D 4 and 5; then the

correct darkening of bubbles will look like the following.
