This passage was adapted from an article written in 1990.
Research data indicate that there is a great deal of poverty in the United States among single-parent families headed by women. This problem could result from the fact that women's wages are only 60 percent of men's. Some economists believe that rigorous enforcement of existing equal pay laws would substantially decrease this wage inequity. But equal pay laws are ineffectual when women and men are concentrated in different occupations because such laws require only that women and men doing the same jobs be paid the same. Since gender concentration exists (for example, 80 percent of clerical workers are women), other economists argue that a comparable worth standard, which would mandate that women and men in any jobs that require comparable training and responsibility be paid the same, should be applied instead. But some policy analysts assert that, although comparable worth would virtually equalize male and female wages, many single-parent families headed by women would remain in poverty because many men earn wages that are below the poverty line. These policy analysts believe that the problem is not caused primarily by wage inequity but rather by low wages coupled with single parenthood, regardless of sex. As a solution, they challenge the government's assumption that a family's income should depend primarily on wages and urge the government to provide generous wage supplements (child and housing allowances) to single parents whose wages are low.
Which of the following is most clearly an example of the policy advocated by the policy analysts mentioned in highlight text?

这个policy是provide generous wage supplement(child and housing allowances) A training,不符合 B support research,不符合 C survey只是调查,没有任何实质性的作用 D 分析也没有实质性的作用 E 正确。提供住房补贴,正是原文括号里的housing allowances
