请教一道曼哈顿里的逻辑题。

这道题的逻辑我有点懵，请大家看看，你们看应该选哪个，说出理由。


The United States government uses only a household's cash income before taxes to determine whether that household falls below the poverty line in a given year; capital gains, non-cash government benefits, and tax credits are not included. However, yearly cash income is not a fool-proof measure of a given household's disposable income. For example, retirees who live off of capital gains from an extensive portfolio could earn hundreds of thousands of dollars, yet be classified by the government as living in "poverty" because this income is not included in the calculation.

Which of the following, if true, validates the contention that the government's calculation methods must be altered in order to provide statistics that measure true poverty?

		For more than 99% of those classified as living in poverty, yearly cash income comprises the vast majority of each household's disposable income.
		While the government’s calculation method indicated a 12.5% poverty rate in 2003, the same calculation method indicated anywhere from a 9% to a 16% poverty rate during the preceding decade.
		Most established research studies conducted by the private sector indicate that the number of people truly living in poverty in the U.S. is less than that indicated by the government’s calculation method.
		Several prominent economists endorse an alternate calculation method which incorporates all income, not just cash income, and adjusts for taxes paid and other core expenses.
		The government’s calculation method also erroneously counts those who do not earn income in a given year but who have substantial assets on which to live during that year.

你是认真的吗

前提：
1 政府通过现金收入来判断一个人是否低于贫困线
2 资本收益、非现金政府福利、税收豁免不包含在标准内

结论：这不是一个好的方法

前提→结论的gap要填补好

OA：C 真正处于贫困的人比用这个方法判别出来的人要少

A 用这个方法判别出来的人现金收入占到可支配收入的99%，这是前提的内容
B 这个方法得到的贫困率在前一个十年的range，em...既不是前提的内容也不是结论内容，也就是说无法通过这个选项结合前提来得到结论：这不是一个好方法
D 有更好的方法，em...有更好的方法并不代表现在的方法不好，我们可以这么理解
E 政府错误地计算了某些群体，我们关心的应该是结果，而这个答案没有explicitly地描述出用这个方法统计出来的结果如何，或许得出的结果make little sense呢
