In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees,these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida.

Which of the following, if true, most seriously weakens the argument given?

People who moved from one state to another when they retired moved a greater distance, on average, last year than such people did ten years ago. People were more likely to retire to North Carolina from another state last year than people were ten years ago. The number of people who moved from one state to another when they retired has increased significantly over the past ten years. The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago. Florida attracts more people who move from one state to another when they retire than does any other state.

题干翻译
在过去十年中，退休后前往佛罗里达的人数比例下降了三个百分点。因为佛罗里达的许多当地企业迎合退休人员，所以这些下降很可能会对这些企业以及佛罗里达的经济产生明显的负面影响。 逻辑链
Retire to FL %↓ → Neg econ effect 问题类型
削弱题 推理过程
论点认为退休后去佛罗里达人数比例下降会对当地企业和经济产生负面影响，要削弱该论点，需找到证据表明即使比例下降，实际人数可能并未减少甚至增加，从而不会产生负面影响。 选项分析
A选项：退休时从一个州搬到另一个州的人去年平均移动距离比十年前更远。移动距离与去佛罗里达退休人数及对佛罗里达经济影响无关，排除。 B选项：去年人们从其他州退休去北卡罗来纳的可能性比十年前更高。说的是去北卡罗来纳的情况，与佛罗里达无关，排除。 C选项：在过去十年中，退休时从一个州搬到另一个州的人数显著增加。虽然去佛罗里达的比例下降，但总人数大幅增加，那么去佛罗里达的实际人数可能不会减少甚至增多，不会对经济产生负面影响，削弱了论点，当选。 D选项：去年退休时离开佛罗里达去另一个州居住的人数比十年前更多。只说离开人数，没涉及进入人数，无法判断对佛罗里达经济的影响，排除。 E选项：佛罗里达在退休人员跨州迁移时比其他任何州吸引的人都多。但不知道整体人数变化和对经济的影响，排除。
