    Directions For Questions

    Directions:The following question has four choices out of which ONLY ONE is correct.

    Following  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, s and t. Any given statement in Column I can match with ONE OR MORE statements (s) in column II. The appropriate bubbles corresponding to the answers to these questions have to be darkened as illustrated in the following example:
