Difficulty: Medium
Correct Answer: Only conclusion I follows
Explanation:
Introduction / Context:
The statement flags contamination in bottled water—precisely the segment marketed as “safe.” We test which conclusion is warranted.
Given Data / Assumptions:
Concept / Approach:
Finding harmful residues in widely consumed products has serious public-health implications (I). But to generalize that “drinking water is harmful” (II) commits a sweeping overgeneralization; the issue is with contaminated bottled water samples, not the act of drinking water per se.
Step-by-Step Solution:
1) Identify scope: “popular brands” → potentially large exposure → public-health risk.2) Reject II: not all water is harmful; treatment standards vary.
Why Other Options Are Wrong:
Only II/Either/Both: overgeneralize beyond the stated context. Neither: ignores the obvious health implication.
Common Pitfalls:
From “some X are contaminated” to “all water is dangerous” is a logic leap.
Final Answer:
Only conclusion I follows.
