Difficulty: Medium
Correct Answer: Only assumption I is implicit.
Explanation:
Introduction / Context:
The recommendation forbids employing illiterate or drunk drivers “at least for children,” implying a safety rationale. We test which assumptions are required.
Given Data / Assumptions:
Concept / Approach:
Forbidding illiterate drivers presumes literacy matters for safety. The phrase “at least for children” signals heightened protection, not status equality across contexts.
Step-by-Step Solution:
1) The ban targets illiteracy and intoxication as risk factors.2) The child-focused caveat presumes additional caution is justified for children, not that children and adults have identical status in all respects.3) Therefore, I is necessary; II is not required by the statement.
Verification / Alternative check:
Even if adults could legally accept higher risk, the policy is minimum protection for children. Thus equality of status is irrelevant to the reasoning.
Why Other Options Are Wrong:
Only II: unrelated. Either I or II: only I is needed. Neither: false; I is required. Both: II adds an unnecessary claim.
Common Pitfalls:
Misreading “at least for children” as a claim about legal or social equality rather than protective priority.
Final Answer:
Only assumption I is implicit.
