Difficulty: Easy
Correct Answer: If statement (II) is the cause and statement (I) is its effect.
Explanation:
Introduction / Context:Rail systems depend on overhead catenary for traction power. A snapped wire typically halts service until repaired.
Given Data / Assumptions:
Concept / Approach:Technical failure (II) directly causes service disruption (I). The reverse is illogical.
Step-by-Step Solution:
1) Identify failure point: catenary break (II).2) Map consequence: immediate stoppage and safety clearance cause delays (I).3) Therefore, II→I.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.
