Difficulty: Medium
Correct Answer: If only reason 2 (R2) and not reason 1 (R1) is the reason for the assertion (A).
Explanation:
Introduction / Context:
The stem asks which stated reason better explains activist demands for prohibition. We must check the factual strength and generality of (R1) and (R2) and whether they plausibly motivate calls for prohibition.
Given Data / Assumptions:
Concept / Approach:
Sound reasons should be framed without sweeping universalities. Public-health and social-order arguments typically focus on harm prevalence and externalities, not absolute fatality claims.
Step-by-Step Solution:
Verification / Alternative check:
Policy debates typically cite measurable social costs and public-health data rather than absolute fatal outcomes.
Why Other Options Are Wrong:
(a) privileges an absolute falsehood; (c) wrongly accepts both; (d) rejects all reasons despite (R2) being sound; (e) unnecessary hedging.
Common Pitfalls:
Treating complex risk as absolute; ignoring the difference between mortality risk and broader social harms.
Final Answer:
Option B: Only (R2) explains (A).
