For the first time in this century, the most recent national census shows that towns with populations under 10,000 are growing more rapidly than cities of more than 1 million. This confirms that people prefer human scale environments to rich, high-density environments. The above argument assumes that (A) the populations of large cities are devclining. (B) the environmental quality of cities is declining. (C) financial oppotunities are the primary reason people live in large cities. (D) people find more financial oppotunities in large cities than in small towns. (E) there are more rich people today than ever before. 实在是想不明白为什么选择D。请各位帮忙。^^ |
