No nation leaped into the 20th century like Japan. For two hundred years, Japan remained and isolated from the rest of the world. It doubted of western ways. In 1854, Commodore Perry of the U. S. Navy sailed into Tokyo Bay. When he showed the people inventions like the telegraph and railroad train, Japan realized what it was missing. Japan has quickly caught up with western technology. It may have even gone past it.
Japan has a population of over 116,000,000. The people are thickly settled on the four main islands. Since only one sixth of the land is arable, Japan relies on imported food. To pay for the imports, Japan exports manufactured goods.
Japan builds and sells cars, motorcycles, television sets, radios and cameras. Textiles and chemicals also made. In Yokohama Harbor, ships are constructed for use by other nations.
The "head start" western nations had may be the reason for Japan's success today. Western countries are still using machines and technology that they developed many years ago. Japan is using newer, improved methods. For example, robots are relieving factory-workers of long, tiring jobs.
Modem technology has brought modern problems. Air and water quality reached dangerous levels in some parts of Japan in the late 1960's. Since then, the Japanese government has applied strong pollution controls.
The main idea of the passage is that Japan ________.
A．surprises the world.
B．Suffers from serious air and water pollution
C．Leads in exporting goods
D．Leads in technology in the world today
