[单项选择]
In the 1940s, urban Americans began a mass move to the suburbs in search of fresh air, elbow room and privacy. Suburbs began to sprawl out across the countryside, since most of those making the move were middle-class, they took with them the tax money the cities needed to maintain the neighborhood, in which they had lived.

Stanford is one of the latest universities that announce a new financial-aid package for those middle-class families. Harvard University was the first one to come to the aid of the middle class. Last December, the university announced sweeping changes to its financial aid policy, eliminating loans and asking students from families with salaries between $ 120,000 and $ 180,000 to pay no more than l0 percent of their family’s income to attend. Then came Duke, which vowed to reduce loans for students with family incomes up to $ 100 ,000 and also try to establish a loan cap for those wealthier ones.
