Statement–Courses of Action (holiday-season train berth surge): There is an unprecedented rise in berth requests on most long-distance trains during the current holiday season; determine which action(s) follow—(I) immediately attach extra coaches to increase capacity, (II) advise passengers to plan travel after the holidays—focusing on demand management and service responsibility.

Given data

• Situation: Demand spike for long-distance train berths during holidays.
• Course I: Expand capacity by adding coaches.
• Course II: Ask people to travel after the holiday.

Concept / Approach
Service providers should attempt feasible capacity augmentation before deflecting demand.

Step-by-step evaluation
Step 1: Course I is a standard, workable measure (subject to rake/traction constraints) and directly addresses demand.Step 2: Course II shifts the burden to passengers and does not solve the stated seasonal need; it is not a logical first response.

Verification / Alternative check
Railways often run special trains or attach coaches in peak seasons—consistent with I.

Common pitfalls

• Recommending inaction or deferral when immediate operational remedies exist.

Final Answer
Only I follows.
