Answer
Correct Answer: (iii) (i)
Explanation
Introduction / Context:The rule is VisitTaj ⇒ (Tourist ∨ Historian). It does not say all tourists/historians visit Taj.
Given Data / Assumptions:
- For any person X, if X visits Taj, then X is tourist or historian.
Concept / Approach:We look for a pair where visiting Taj justifies labeling the person as tourist or historian. That is (iii) then (i) for Siya.
Step-by-Step Solution:
From (iii) Siya visits Taj ⇒ conclude (i) Siya is historian or tourist.Statements about Riya are independent; not required by the rule.Verification / Alternative check:Implication direction is from visiting to category membership, not the reverse.
Why Other Options Are Wrong:(iv) (ii) assumes visiting ⇒ tourist for Riya without (iv) being given by the rule. (i) (iii) flips order; (i) alone does not imply (iii).
Common Pitfalls:Assuming all tourists/historians must be visitors (converse error).
Final Answer:(iii) (i)
