Logical deduction – Red Riding Hood and the Big Bad Wolf: "When Red Riding Hood comes, the Big Bad Wolf is not far behind." Choose the correct pair. (i) Big Bad Wolf is behind. (ii) Red Riding Hood comes. (iii) Big Bad Wolf is not far behind. (iv) Red Riding Hood does not appear.

Introduction / Context:The implication is RRHComes ⇒ WolfNotFarBehind. We need a pair reflecting that co-occurrence.

Given Data / Assumptions:

• If RRH appears, the wolf is close behind.

Concept / Approach:Select (ii) with (iii), aligning antecedent and consequent.

Step-by-Step Solution:

Verification / Alternative check:(ii) (i) is weaker and uses a different predicate ("behind" vs "not far behind").

Why Other Options Are Wrong:They either contradict or fail to capture the stated consequence.

Common Pitfalls:Overlooking the "not far" qualifier.

Final Answer:(ii) (iii)
