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.

Which of the following, if true, would cast the most doubt on the viability of the college administrators’ plan described above?

(A) Profit-making corporations interested in developing products based on patents held by universities are likely to try to serve as exclusive sponsors of ongoing university research projects. （不相关：赞助方式）
(B) Corporate sponsors of research in university facilities are entitled to tax credits under new federal tax-code guidelines. （不相关：赞助企业好处）
(C) Research scientists at Logos University have few or no teaching responsibilities and participate little if at all in the undergraduate programs in their field. （不相关：科学家职责）
(D) Government-sponsored research conducted at Logos University for the most part duplicates research already completed by several profit-making corporations. （相关：无人购买）
(E) Logos University is unlikely to attract corporate sponsorship of its scientific research. （不相关：吸引赞助）
这是原题目，我觉得 ADE都有削弱的的意思，正确答案是D 哪位大牛能指导一下～
我的思路是这样的 A 政府新法规大学可以卖专利--------》B Logo大学希望通过卖专利得到fund来提高教育。
                            削弱找 C-->B （其他方法可以得到fund）这里不适用 因为主题干没有提及A是唯一方法
                                        A---》C （卖专利会导致其他结果）
                           
另外GWD的解题方法我有些 迷惑了，削弱题A x Bx ---》X 都是错误选项，
但是这道题我总觉得AX 其实可以， AX (卖专利的不可行性，比如说 卖不出去？ 这是正确答案D所提到的）
小妹刚刚解除逻辑题，希望各位大侠能帮助指点迷津～ 谢谢～

Hotco oil burners, designed to be used in asphalt plants, are so efficient that Hotco will sell one to the Clifton Asphalt plant for no payment other than the cost savings between the total amount the asphalt plant actually paid for oil using its former burner during the last two years and the total amount it will pay for oil using the Hotco burner during the next two years. On installation, the plant will make an estimated payment, which will be adjusted after two years to equal the actual cost savings.

Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?

(A) Another manufacturer’s introduction to the market of a similarly efficient burner （不相关：竞争对手）
(B) The Clifton Asphalt plant’s need for more than one new burner （不相关：更多新设备，支持）
(C) Very poor efficiency in the Clifton Asphalt plant’s old burner （不相关：旧设备效率低，支持）
(D) A decrease in the demand for asphalt （不相关：需求下降）
(E) A steady increase in the price of oil beginning soon after the new burner is installed （相关：成本增加）
我觉得这题BDE都可以削弱，B 买更多的新设备 将花更多的钱，2年内cost saving达不到
                                           D 需求下降，new burner给asphalt的供给少，产出少，相应
                                               的能节省的钱就少
                                            E正确答案，成本增加，cost saving达不到～
如把 BD 排除呢？；

Although the discount stores in Goreville’s central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long. In the five years since the opening of Colson’s, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson’s.

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

(A) Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened. （不相关：顾客减少，影响不确定）
(B) Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores. （相关：否定前提）
(C) At present, the central shopping district has as many stores operating in it as it ever had. （不相关：店铺未减少，支持）
(D) Over the course of the next five years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades. （不相关：人口增加，支持）
(E) Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s. （不相关：其他店铺）
被这题弄糊涂了，题干第一句是说 店竞争比不过 spendless 折扣店但店铺不会减少，第二句是说店竞争 比不过 非折扣店 colson‘s  
哪个算是argument？ 第一句还是第二句？
看答案分析的话，结论或者事实应该是第一句的后半段，购物区的店铺不会减少
选项B 中的折扣店是指新开的小店折扣店增加呢还是 colons变成折扣店了？
