How does the author develop the central idea that high-speed rail is significantly better than other rail systems?

A. by giving positive stories from high-speed rail riders
B. by providing a series of examples of the benefits of high-speed rail
C. by presenting criticism of high-speed rail and showing how each one is false
D. by showing ways that traditional rail systems are worse than high-speed rail

The author argues that high-speed rail is superior by providing examples of its benefits, including environmental efficiency, economic impact, and improved transportation capacity compared to traditional rail systems.

Explanation:

The author develops the central idea that high-speed rail is significantly better than other rail systems by providing a series of examples of the benefits of high-speed rail. These benefits include reducing highway traffic, which in turn may lead to reductions in air pollution and vehicular injuries and deaths. High-speed trains are also more efficient in terms of carbon dioxide emissions per passenger compared to planes, and they can significantly boost local economies by increasing connectivity and jobs. Other nations' successful experiences with high-speed rail also lend support to this central idea. The author's arguments suggest that the innovation and efficiency of high-speed rail far outweigh the traditional systems in terms of speed, capacity, and environmental impact.
