Statement: The municipal authority blocked traffic in and around the temple on the main festival day. Assumptions: I. A very large number of devotees are likely to visit the temple on the main festival day. II. People travelling to areas near the temple may postpone their journey by a day unless the visit is very urgent. Which of the above assumptions is implicit in the statement?

Introduction / Context:
Authorities often impose traffic restrictions near major religious sites on festival days to manage crowd surges and ensure safety. The question asks which background belief is necessary for the decision to block traffic in and around the temple on the main festival day.

Given Data / Assumptions:

• Action: Traffic blocked near the temple on the festival day.
• Assumption I: A very large crowd is expected at the temple.
• Assumption II: Non-devotee travelers will likely postpone trips unless highly urgent.

Concept / Approach:
The primary rationale for traffic blocks is anticipated congestion from large footfall. Without such an expectation, blanket traffic restrictions would be gratuitous. Whether other travelers postpone their trips is a secondary behavioral speculation—not a prerequisite for imposing a closure intended to protect pedestrians and manage flows.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming policies depend on public compliance decisions (e.g., postponement). Here, enforcement is independent of such decisions.

Final Answer:
Only Assumption I is implicit.
