17.Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.
Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.
(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.
(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.
(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.（C）
(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.

这一题题干的最后一句话和题目有什么关系呢我愣是没看明白
20.The following proposal to amend the bylaws of an organization was circulated to its members for comment.
When more than one nominee is to be named for an office, prospective nominees must consent to nomination and before giving such consent must be told who the other nominees will be.
Which of the following comments concerning the logic of the proposal is accurate if it cannot be known who the actual nominees are until prospective nominees have given their consent to be nominated?

(A) The proposal would make it possible for each of several nominees for an office to be aware of who all of the other nominees are.
(B) The proposal would widen the choice available to those choosing among the nominees.
(C) If there are several prospective nominees, the proposal would deny the last nominee equal treatment with the first.
(D) The proposal would enable a prospective nominee to withdraw from competition with a specific person without making that withdrawal known.（E）
(E) If there is more than one prospective nominee, the proposal would make it impossible for anyone to become a nominee.

好吧我承认这一题我真的不知所云
15.Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it. The trade of businesses selling and renting videos is still buoyant, because the number of homes with video recorders is still growing. But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.
Which of the following, if true, would most seriously weaken the conclusion above?
(A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes.
(B) Among the items handled by video distributors are many films specifically produced as video features.
(C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product.
(D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them.（D）
(E) In a shrinking market, competition always intensifies and marginal businesses fail.
我这一题想找一个证明消费者会一直对video recorders 的证据可是D选项怎么削弱了丫

But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.
Which of the following, if true, would most seriously weaken the conclusion above?即反驳：video business饱和（参与卖片儿的公司多了）后就会不好
(A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes.什么时候被认为是饱和，无关
(B) Among the items handled by video distributors are many films specifically produced as video features.他们卖什么片儿，无关
(C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product.顾客对新放映机（无关）性能满意
(D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them.（D）（说明只是early buyers自身特点喜新厌旧导致他们不再买片儿，而其他buyers可能会继续买，所以即使更多business参与进来，因为有recorders的家庭越来越多，所以即使饱和也可能有忠实的fans天天买片儿）
(E) In a shrinking market, competition always intensifies and marginal businesses fail.（萎缩的市场的特征，无关）

Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.
Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT: 题目问：下面除了哪个，其他都是反对用lists上的排名作为医院服务的质量的指标的逻辑考虑

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.因为rank的数据上的差别小，所以可能没什么参考性
(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.医院政策差别导致deaths数量不能说明问题
(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.题目已经说了“The data have been adjusted to allow for differences in the ages of patients.” 所以old和younger的比较，无关
(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital 同B
(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals. 同B
