Q13:

    

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, this decline is likely to have a noticeably negative economic effect
on these businesses.

    

 

    

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

    

 

    

1. Florida attracts more people who move from
        one state to another when they retire than does any other state.
2. The number of people who move out of Florida to accept
        employment in other states has increased over the past ten years.
3. There are far more local businesses
        in Florida
        that cater to tourists than there are local businesses that cater to
        retirees.
4. The total number of people who
        retired and moved to another state for their retirement has increased
        significantly over the past ten years.
5. 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.

答案是D，不过我觉得答案D中退休的人数目增加了和BUSINESS之间有关系吗？相反，C项中说许多BUSINESS是针对游客而不是针对退休的人的，这说明退休的人数目或PERCENTAGE增减对BUSINESS的影响相对小。

这题我搞明白了。。。。。。题干说的是退休的人会对专门针对退休的商业有影响，所以虽然百分比下降了但如果总人数上升了还是对针对退休的人的商业没影响。。。。和旅游的没关系的说。。。。。。啊。。。大头了。

我还是没明白，d 不是说的是other state吗

它和Florida有什么关系? 我觉得反而是support了？因为到别的州多了，在florida就必然更少了
