Difficulty: Easy
Correct Answer: If neither (R1) nor (R2) is the reason for the assertion (A).
Explanation:
Introduction / Context:The epithet “Roof of the World” references very high elevations and central highland plateaus. The task is to test whether the given reasons logically explain the title.
Given Data / Assumptions:
Concept / Approach:The nickname arises from altitude/physiography (very high terrain at the junction of multiple ranges). R1 is true but locational and not explanatory; R2 is not a recognized reason for the epithet.
Step-by-Step Solution:
1) Check R1: Being in Asia does not entail “roof” status; many Asian ranges are not so called.2) Check R2: “Protecting Asia” neither defines nor historically underpins the moniker.3) Hence, neither R1 nor R2 explains A.Verification / Alternative check:An appropriate reason would mention extreme elevations and high plateau characteristics; neither R1 nor R2 does.
Why Other Options Are Wrong:A/B/C attribute explanatory power that is missing.
Common Pitfalls:Accepting true-but-irrelevant facts (R1) as reasons; relying on unverified generalities (R2).
Final Answer:If neither (R1) nor (R2) is the reason for the assertion (A).
