Difficulty: Easy
Correct Answer: (ii) (iii)
Explanation:
Introduction / Context:
The statement is (~Walk) OR Read. Any situation with at least one true is acceptable.
Given Data / Assumptions:
Concept / Approach:
Choose a pair that makes the disjunction obviously true.
Step-by-Step Solution:
(ii) Not walk; (iii) Reads → certainly satisfies (~W) OR R (both parts true).
Verification / Alternative check:
(ii)(iv) would force both (~W) and (~R), which still satisfies the OR (since ~W is true) but is less aligned with common-sense reading tests; (ii)(iii) is the cleanest.
Why Other Options Are Wrong:
They introduce contradictions or weaker, less direct support.
Common Pitfalls:
Assuming exclusivity where none is given.
Final Answer:
(ii) (iii)
