Cause & Effect — Identify the Relationship:\nI. Train services in suburban areas of the city were disrupted for four hours.\nII. The overhead electrical wire snapped between two suburban stations.\nWhich option best captures the causal link between I and II?

Introduction / Context:
Rail systems depend on overhead catenary for traction power. A snapped wire typically halts service until repaired.

Given Data / Assumptions:

• II: Overhead wire snapped between two stations.
• I: Four-hour disruption in services.
• Assume electric multiple units rely on intact catenary.

Concept / Approach:
Technical failure (II) directly causes service disruption (I). The reverse is illogical.

Step-by-Step Solution:

Verification / Alternative check:
Disruptions can have other causes, but the stem explicitly provides the wire snap as the proximate cause.

Why Other Options Are Wrong:
They deny the evident technical causality.

Common Pitfalls:
Overlooking that even short catenary faults can ripple into multi-hour disruptions.

Final Answer:
Option B: Statement II is the cause and statement I is its effect.
