1. Use the following passage to answer the question.
Japan has long had a large population for its land area, especially since the Baby Boom following World War II. This is particularly true in Japan’s cities. For example, according to a 2010 census, the metropolitan Tokyo-Yokohama area has an estimated 35 million residents. The population of the entire country is roughly 128 million. Tokyo-Yokohama is considered the most populous urban center in the world. Some Japanese cultural traditions have been attributed to such crowding. For example, the Japanese people use very formal behaviors like bowing, and use very formal language during social interactions. One theory is that this formality, at least in part, is a means of creating psychological distance and space between individuals, as sufficient physical space is lacking. The expression "too close for comfort" may aptly describe the situation in Japan’s most crowded cities, and this physical proximity is offset by reducing social closeness.
In this passage, the author’s main purpose is to
A. Give a complete summary of the demographic features of Japan.
B. Describe a hypothesis of social behavior based on demographics.
C. Explain why the population of Japan has increased since the war.
D. Give a very detailed description of acceptable Japanese manners.
E. Argue that Japan has the highest population density in the world
