Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
Assumption I is necessary—otherwise, there is no normative basis for prohibiting suburban entries during peak hours.Assumption II is not necessary—congestion may have multiple contributors; targeting one major contributor can still be justified.Verification / Alternative check:
Keep I and drop II: The policy retains sense. Keep II and drop I: The ban lacks a directed rationale.Why Other Options Are Wrong:
II or Both: Overstate the requirement by demanding an absolute about city vehicles.Common Pitfalls:
Assuming a policy must eliminate all causes rather than address a significant one.Final Answer:
Only assumption I is implicit
