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?
- No household in Merton county has an annual income of $60,000 or more.
- Some households in Merton county have an annual income between $40,000 and $60,000.
- The number of households with an annual income of more than $40,000 is greater in Merton than in Sommer county.
- Average annual household income is higher in Sommer than in Merton county.
- The percentage of households with an annual income of $80,000 is higher in Sommer than in Merton county.
这题答案是B,但是我觉得E也很合理,M城市收入40000以上的人占的百分比最多,而S城市收入60000以上的人占的百分比最多,那么收入80000以上的人的百分比S大于M,不是很合理吗?因为M城市的人大多集中在40000到60000之间。不选B是因为这个不需要推啊……它只是说some并没有涉及M和S的比较嘛……
