标题: GWD-3-30

The percentage of households with an annual income of more than $40,000 is higher in Merton county than in any other county. However, the percentage of households with an annual income of $60,000 or more is highest in Sommer county.

If the statements above are true, which of the following can properly be concluded on the basis of them?

A. No household in Merton county has an annual income of $60,000 or more.

B. Some households in Merton county have an annual income between $40,000 and $60,000.

C. The number of households with an annual income of more than $40,000 is greater in Merton than in Sommer county.

D. Average annual household income is higher in Sommer than in Merton county.

E. The percentage of households with an annual income of $80,000 is higher in Sommer than in Merton county.

涉及甲乙比较,答案肯定有两者比较,故排除AB. E 中的80,000不是文中给出的数值,排除. 比较CD, C中只涉及了绝对数,错.选D

以上是我的思路,但是答案确是B,完全出乎意料,B完全没有涉及对比嘛

B 中是" SOME HOUSEHOLD" 表示有些家庭是40000-60000之间, 所以肯定没有错.

其他选项太绝对.

这题我也做错了。又仔细看看题才明白。

more than $40,000 means >40000，但是这里又不可能都是在大于60000里的。否则Sommer county 在大于60000里就不可能拍第一了。

$60,000 or more means >=60000

不知道我说清楚了没有。
