請依下文回答第 47 題至第 50 題：Japan has long been a pioneer in high-speed rail. It introduced bullet train, or Sinkansen, to the world in 1964 on theeve of the Tokyo Olympics. But other countries have caught up. France and Germany developed high-speed trains thatmatched the Japanese speeds. China has built a high-speed network that surpasses Japan’s in its reach if not its speed.Japan plans to begin construction of its first intercity maglev line next year, linking Tokyo with Nagoya and, eventually,Osaka. In tests, the Japanese maglev has reached speeds up to 580 kilometers an hour, the world record for a train.When it comes to maglev, though, there is still question of credibility. With the Japanese maglev, levitation occurs about145 kilometers an hour. That is when the wheels, shod with rubber tires, lift off the concrete guideway. Then the maglev trainfloats 10 centimeters about the U-shaped guideway, held aloft and propelled toward by superconducting magnets.In Japan, many remain skeptical of the financial feasibility of the Tokyo-Osaka maglev line. The Tokyo-Nagoya portionis expected to be completed by 2027, with the Nagoya-Osaka stretch to follow in 2045. By that time the population of Japanwill have declined to about 105 million from the current 127 million.
47 In what aspect is the Chinese high-speed network better than the Japanese one?
(A)in its speed
(B)in its reach
(C)in its cost
(D)in its appearance
