Difficulty: Medium
Correct Answer: If either Conclusion I or II follows
Explanation:
Introduction / Context:The actor’s rule is exclusive: for any given show, he charges either the full fee or nothing. We are asked about the most recent show’s payment status.
Given Data / Assumptions:
Concept / Approach:Given the disjunction (full OR none) and absence of further detail, the only inference is that exactly one of the two must be true, though we cannot specify which one.
Step-by-Step Solution:
• I: Could be true but not established.• II: Could be true but not established.• The logically safe evaluation is: one of them follows as a necessary alternative, but we cannot pick which. Hence “either I or II.”Verification / Alternative check:Exclusive rule applies to each show independently; absent show-specific info, the binary remains open.
Why Other Options Are Wrong:
• Only I / Only II: Assert a side without evidence.• Neither: Contradicts the actor’s stated practice.• Both: Mutually exclusive by the actor’s rule.Common Pitfalls:Confusing “we cannot tell which” with “neither.”
Final Answer:If either Conclusion I or II follows.
