Read the passage below carefully:
While municipal planners in rapidly expanding African megacities frequently champion formal Bus Rapid Transit (BRT) networks as the ultimate panacea for urban congestion, the unyielding resilience of informal minibus transit systems demonstrates that high-capacity infrastructure alone cannot resolve urban mobility challenges. Decades of urban transit reforms reveal that commuter reliance on informal minibuses stems not from an aversion to modernization, but from the unmatched spatial flexibility and hyper-local responsiveness these informal operators offer to low-income outer-suburban settlements that formal routes consistently neglect. Although BRT corridors undeniably reduce travel times along major trunk lines and lower per-commuter carbon emissions, their rigid schedules and fixed station locations fail to accommodate the non-linear, fragmented daily travel patterns of informal sector workers. Consequently, sustainable urban mobility depends not on displacing informal operators, but on systematically integrating their operational flexibility with high-capacity public transit infrastructure.
Which of the following statements best expresses the main idea of the passage?
- Sustainable urban transport solutions require integrating informal transit networks with formal high-capacity systems rather than replacing them.Answer
- BInformal minibus transit systems provide greater spatial flexibility and hyper-local coverage than formal Bus Rapid Transit networks.
- CFormal Bus Rapid Transit networks fail to alleviate traffic congestion because suburban commuters are inherently opposed to modern transit infrastructure.
- DMunicipal authorities should abolish Bus Rapid Transit projects to protect informal sector transport jobs in suburban areas.
