Statement & Assumption — A planning engineer says: “Traffic is very heavy between 5 PM and 7 PM. We need a flyover in this area.” Which assumptions are implicit? I. Heavy traffic is intended to be maintained. II. Previous planners did little about heavy traffic. III. A flyover is likely to solve the heavy-traffic problem.

Introduction / Context:
The proposal recommends a flyover as a remedy for peak-hour congestion. We test which premises are necessary.

Given Data / Assumptions:

• Problem: heavy traffic, 5–7 PM.
• Proposed remedy: build a flyover.

Concept / Approach:
Only Assumption III is necessary: the remedy must plausibly alleviate congestion. Assumption I is absurd and not required; no one intends to “maintain” heavy traffic. Assumption II is unnecessary; the argument for a flyover does not depend on judging previous planners.

Step-by-Step Solution:
Affirm III: Links remedy to problem.Reject I and II: Irrelevant or gratuitous claims.

Final Answer:
Only III is implicit
