What did they begin building in Mexico City in 1967 to improve the traffic situation?

• A. The metro
• B. The airport
• C. A new highway
• D. A ring road

Answer: (A)

When a city struggles with heavy traffic, the most effective fix is a mass transit system that can move lots of people quickly. In 1967, Mexico City began building its metro to provide a fast, reliable alternative to cars and to ease the burden on crowded streets. A subway and elevated rail network can move far more passengers than cars in the same amount of time, helping to shorten commutes and reduce congestion in core areas. This choice fits the situation because it targets daily commuting on a large scale and creates a backbone for future urban mobility, connecting many neighborhoods with rapid service and integrating with buses and other transit. Other options don’t fit as well for a citywide traffic solution: building an airport or a new highway doesn’t directly replace daily car trips across the city, and while a ring road can help, it doesn’t offer the high-capacity, rapid transit that a metro provides.
