Match List–I with List–II and give your answer using the codes given below : Codes : (P) (Q) (R) (S)List I (Logical Rule) List II (Logical Relation) (P) Conjunctive rule (1) AND (Q) Disjunctive rule (2) If and only if, THEN (R) Conditional rule (3) IF..............THEN (S) Biconditional rule (4) OR
(1) (4) (3) (2)
In concept formation, logical rules specify how attributes are combined to define a concept (Bourne, 1970).
| Logical rule (List I) | Logical relation (List II) | Reason |
|---|---|---|
| (P) Conjunctive rule | (1) AND | Both attributes must be present (red AND square). |
| (Q) Disjunctive rule | (4) OR | Either attribute, or both, qualifies (red OR square). |
| (R) Conditional rule | (3) IF ... THEN | If one attribute is present, the other must also be present. |
| (S) Biconditional rule | (2) If and only if, THEN | One attribute is present if and only if the other is present. |
Research shows conjunctive rules are the easiest to acquire, followed by disjunctive, conditional and biconditional rules.
Hence, the answer is (P)–(1), (Q)–(4), (R)–(3), (S)–(2).
