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?
A.Florida attracts more people who move from one state to another when they retire than does any other state.
B.The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
C. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
D. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
E. 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。我知道答案d是有可能削弱的，但是我不明白a为什么不行，a同样是有可能削弱阿。a中florida既然能比其他州能吸引更多退休的人，证明这也是他的优势，对经济影响不大

90. A new law gives ownership of patents—documents providing exclusive right to make and sell an invention—to universities, not the government, when those patents result from government-sponsored-university research. Administrators at Logos University plan to sell any patents they acquire to corporations in order to fund programs to improve undergraduate teaching.
　　谁能帮忙翻译一下这句话阿~~感激感激~

其实这题是典型的PERCENTAGE和NUMBER的问题
题干说的是PERCENTAGE，就应该有意识的在选项中找到支持虽然PERCENTAGE下降，但是不代表NUMBER下降的例子。D很明显解决了这个问题。这种比例和数字的比较时逻辑题的常见题型。
A的问题在于即使FOLORIDA跟别的州相比吸引的人最多，也无法改变它自己可能一年比一年人数减少的颓势。毕竟这题的结论针对的是FLORIDA的经济影响，应该是FLORIDA自己和自己往年比，而不应该是和别的州相比。就像大环境不好，即使你依然是市场上销售第一，也极有可能其实你今年的销售额比去年低很多。
