It can be inferred from the passage that ______.

参考解析：

推理判断题。根据第三段最后一句“Shipping between China and European countries on the railway takes one-third the time of sea transportation, and goods can be delivered at only one-fifth the cost of air transportation.”可知，中国和欧洲国家之间的铁路运输需要三分之一的海运时间，而货物的运送成本只有空运的五分之一，所以A项表述正确；B项文中未提及；根据最后一段“This Japanese documentary gives a vivid description that China’s steady advance and contribution to the development of the world has made it the second largest economy in the world.”可知，中国对世界的发展做出了贡献，是世界第二大经济体，但并未说明中国在世界运输和经济领域发挥着最重要的作用，所以C项表述错误；根据倒数第二段“It also shows many ordinary Chinese farmers cultivating farmland in Central Asia as well as Chinese merchants involved in the Eastern European markets and those who find opportunities in the mass e-commerce world. By getting involved in the Belt and Road construction, they enriched themselves and realized their dreams.”可知，许多在中亚耕种农田的普通中国农民，以及涉足东欧市场的中国商人和在大规模电子商务世界中找到机会的人。通过参与“一带一路”建设，他们充实了自己，实现了自己的梦想。但未说明他们会变得更富裕，所以D项表述错误。故选A。
