OG-33－purchasing power

33. Rural households have more purchasing power than do urban or suburban households at the same income level, since some of the income urban and suburban households use for food and shelter can be used by rural households for other needs.

Which of the following inferences is best supported by the statement made above?
A. The average rural household includes more people than does the average urban or suburban household.
B. Rural households have lower food and housing costs than do either urban or suburban households.
C. Suburban households generally have more purchasing power than do either rural or urban households.
D. The median income of urban and suburban households is generally higher than that of rural households.
E. All three types of households spend more of their income on food and housing than on all other purchases combined.

我做题 时，怎么感觉 这道题 更像 支持题，而不是 归纳题 ？ 怎么回事？ 这道题到底什么题？ 我晕了。。

而且我认为B 选项  ，更 能做支持作用。

即：结论是：Rural households have more purchasing power than do urban or suburban households at the same income level,

前提是：since some of the income urban and suburban households use for food and shelter can be used by rural households for other needs.

B刚好，补充前提，得到 结论。。

请NN 帮助：

还有 PURCHASING POWER 是什么意思： 我原以为是：购买力=人的数量+ MONEY+购买欲望，这样觉得A也到能被退出来！！  

请NN 帮忙。。

答案是B啊，有什么问题？

这是的重点是 since推出结论，而你要找到什么东西来说明"since"有道理。

since 是since some of the income urban and suburban households use for food and shelter can be used by rural households for other needs.

所以，和since相关的只有B

我原以为 这题已有结论。。 结论是：Rural households have more purchasing power than do urban or suburban households at the same income level,

你的意思 是不是说，这不是 结论，而是 一个前提。。。

可我体会不到这是一个前提呀。。 谢谢指导。。

不是的，可能是我没讲清，不好意思

这段话的意思是

A（观点）　因为(since)　B（理由）

问题是这么问的，下面推论能更好的支持理由对观点的说明，所以是答案B了
