Critical Reasoning — Assumptions Statement: The Municipal Corporation bans entry of vehicles from suburban areas into the main city via main routes during peak hours to avoid traffic congestion. Assumptions to evaluate: I. People from suburban areas should not bring vehicles during peak hours. II. Vehicles of city residents do not cause congestion.

Introduction / Context:
Policy announcements imply a view about what should or should not happen to achieve a goal. Here the goal is to reduce peak-hour congestion by restricting suburban vehicles on main routes. We must identify the minimum presuppositions enabling this ban to make sense.

Given Data / Assumptions:

• Decision: Ban suburban vehicles on main routes during peak hours.
• Assumption I: Suburban commuters ought to avoid bringing vehicles then (normative backing of the ban).
• Assumption II: City residents’ vehicles are not a source of congestion.

Concept / Approach:

• A ban directed at a specific group assumes curbing that group’s vehicles will help; it carries an implied “should not” for that group at that time.
• However, the policy need not assume that city vehicles never cause congestion; the ban could still be helpful even if city vehicles contribute to some extent.
