Statement: The weather bureau has forecast heavy rainfall during the next week, which may cause water-logging in several parts of the city.\nCourses of Action:\nI. Give the bulletin wide publicity through mass media.\nII. Keep civic pumping systems and de-watering equipment ready to remove accumulated water.\nIII. Advise people to stay indoors during this entire period.

Introduction / Context:
With advance warning of heavy rain and possible water-logging, authorities must both inform the public and prepare infrastructure to mitigate impact.

Given Data / Assumptions:

• Forecast of heavy rainfall next week.
• Risk of water-logging in multiple areas.

Concept / Approach:
I ensures citizens receive timely information to plan commutes, secure property, and avoid high-risk zones. II ensures readiness of pumps, crews, generators, and emergency hotlines—directly addressing predicted water-logging. III, a blanket advice to stay indoors for the entire week, is overbroad; advisories should be time- and locality-specific (e.g., during intense spells, red-alert windows).

Step-by-Step Solution:
1) Implement I: maximize reach via radio, TV, SMS, social media, and ward notices.2) Implement II: pre-position pumps, clear storm drains, test equipment, arrange backup power.3) Reject III in its blanket form; issue targeted advisories instead.

Verification / Alternative check:
Disaster-readiness protocols prioritize risk communication and infrastructure preparedness; blanket lockdown-style advisories are reserved for extreme alerts, not generic weekly forecasts.

Why Other Options Are Wrong:
Only II or None underplay public information; II & III or All overreach with an impractical general stay-indoors directive.

Common Pitfalls:
Issuing non-specific, overly restrictive guidance that the public cannot realistically follow for days.

Final Answer:
Both I and II follow.
