, (P) (Q) (R) (S) (T) in Column I matches with entries (Q), (R) and (T), then darken these three bubbles in the ORS. Similarly, for entries Carbonate (P) Siderite

, (P) (Q) (R) (S) (T) , Sulphide (Q) Malachite

and (P) (Q) (R) (S) (T) and Hydroxide (R) Bauxite

Column II has five entries (P), (Q), (R), (S) and (T) Match the entries in Column I with the entries in Column II One or more entries in Column I may match with one or more entries in Column II The ORS contains a 4 x 5 matrix whose layout will be similar to the one shown below: (P) (Q) (R) (S) (T) For each entry in Column I, darken the bubbles of all the matching entries. For example, if entry . Marking scheme: For each entry in Column I, +2 If only the bubble(s) corresponding to all the correct match(es) is (are) darkened. 0 If none of the bubbles is darkened -1 In all other cases Match the anionic species given in Column I that are present in the ore(s) given in Column II Column I Column II Oxide (S) Calamine
