II. People contribute to pollution and traffic by using personal vehicles.
Show answer & explanation
Correct answer: D
Explanation
Statement: 'Use Metro trains to reduce traffic congestion and air pollution in the city.' – A government appeal.
Analysis of Assumptions/Inferences:
• I. Metro trains are a more eco-friendly mode of transport: Valid. The appeal suggests that using Metro trains reduces air pollution, which directly implies that Metro trains are an environmentally cleaner and friendlier mode of transport compared to other existing alternatives.
• II. People contribute to pollution and traffic by using personal vehicles: Valid. The appeal urges citizens to switch to Metro trains to reduce congestion and pollution, which naturally implies that the current use of personal/private modes of transport significantly adds to traffic and pollution.
Therefore, both I and II follow.
Correct Option: (D)
