This section contains 2 questions. Each question contains statements given in two columns which have to be matched. The statements in column I are labeled A, B, C and D, while the statements in Column II are labeled p. q, r, and s. Any given statement in column I can have correct matching with ONE or MORE statement(s) in column ll. The appropriate bubbles corresponding to the answers to these questions have to be appropriately bubbled as illustrated in the following example. If the correct matches are A-p, B-p, B-q, B-s, C-p. C-r, and D-q, then the correctly bubbled matrix should be as shown above.
