Here each question contains statements given in two column which have to be matched. Statements in columns I are labelled as A, B, C and D where as the statements in column II are labelled p, q, r and s. The answers to these questions are to be appropriately bubbled as illustrated in the following example. If the correct matches should like the following. {:("Column I", "Column II"),("(A) Hydrophosphorus acid", "(p)" +5),("(B) Phosphoric acid", "(q) tribasic"),("(C) Pyrophosphoric acid" ,"(r)" +1),("(D) Metaphosphoric acid", "(s) mono basic"):}
