In the United States, of the people who moved from one state to another when they retired, 定语前置 the percentage who retired to Florida has decreased by three percentage points over the past ten years.
the percentage= the peple retired to Florida
The people who moved from one state to another last ten years
D。The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
a中说Florida attracts more people who move from one state to another when they retire than does any other state. 应该是个无关比较,因为即使attract more people than other states 但是如果总人数下降了,还是会有影响的.所以weaken 不了结论
bec应该都是support来的
d中说,retired to another state的人多了, 所以就不会有影响了, 但是我觉得题目有点不完整,应该补充总人数retaire to florida 的人多了才好,因为如果那些retaire to 其他州的人增加而去florida 的人不见增加的话,那也没有用.
