LUXIN CRITICAL REASONING LOOSE-LEAFING
he cost of flood damage since 1980 has been greater in areas that have adopted flood-control measures than in those that have not. Thus, flood-control projects are expensive engineering mistakes and a substantial waste of resources.

Which of the following, if true, would be most damaging to the argument above?
(A)Those areas that had not suffered flood damage before 1980 are the only ones that have not adopted flood-control measures
(B)Since 1980, those areas that have taken flood-control measures have suffered greater flood damage than they did in the previous decade
(C)The cost of flood damage has increased every year since 1980
(D)Faulty engineering has not been the only cause of the failure of flood-control projects
(E)The amount of rainfall since 1980 has been substantially greater than normal
A):A

11. Studies show that treatment of stress-related disorders with psychotherapy can dramatically cut a person’s need for medical treatment for those disorders. Insurance companies could, therefore, lower their costs by subsidizing psychotherapy and thereby encouraging people who have stress-related disorders and are not now using psychotherapy to do so.

The plan above depends on the assumption that

(A)people who have stress-related disorders tend to have little faith in psychotherapy
(B)any person with a stress-related disorder can be effectively treated with psychotherapy
(C)the projected cost to insurance companies of medical treatment for stress-related disorders exceeds the cost of the proposed subsidies for psychotherapy for those disorders
(D)any stress-related disorder that cannot be treated effectively with conventional medical treatment can be treated effectively with psychotherapy
(E)few people who have medical insurance are treated for stress-related disorders
A):C
11. In order to reverse a downward trend in occupancy rates, many hospitals are now turning to advertising and are also offering, for an extra fee, new amenities such as gourmet meals, luxury rooms, and valet parking.

Which of the following, if it were the reason that the beds in the hospitals involved were being left empty, would increase the likelihood that the marketing technique mentioned above would be effective?
(A)The population of the areas around the hospitals is generally healthier than in the past.
(B)Hospital costs are prohibitively high for many people.
(C)Patients have been choosing other hospitals offering better amenities than those previously available in the hospitals involved.
(D)Many medical procedures that once required hospitalization are now done in doctors offices or in clinics with limited facilities.
(E)The hospitals involved do not offer important medical services that are available elsewhere.
A):C
12.For large farms to be as productive as they can be, their owners need to invest heavily in expensive machinery. This typically requires them to go into considerable debt, and interest on this debt is then a significant  fixed cost. This high fixed cost makes those farmers vulnerable to operating losses if the prices of their products drop.

The information above best supports which of the following inferences about large farms?
(A)They can be highly productive without being profitable.
(B)The tend to be so highly productive that they drive down market prices.
(C)They tend to be consistently profitable if their owners borrow at low interest rates.
(D)They respond to operating losses by increasing their productivity.
(E)They cannot be profitable if their owners depend on credit.
A):C

1/有些费解，不过bcde肯定都不对。只能是a了。a想说的似乎是：没有建设防洪工程的地方都是些不经常发洪水的地方，所以它们遭受到的洪水损失当让要小于建了防洪工程但经常发洪水的地方。

11/c好像是比较容易得出的答案。题干说保险公司可以lower their costs by subsidizing psychotherapy and thereby encouraging people who have stress-related disorders and are not now using psychotherapy to do so，那就意味着假定了subsidizing psychotherapy的成本低于medical treatment成本。

11/这是一个排除他因的加强题。病人不来医院的原因可以很多，比如（a）社区居民健康得很根本不生病、（b）交不起医疗费、（c）医院医疗设施太差、（d）个人诊所的竞争、（e）医疗技术太低，为了加强结论，必须选c来排除其他四个条件abde，来表明结论是正确的。

12/bde都是没有根据的。我一开始选的是a，看见答案后想了想，c应该更好，因为c有更多的题干信息支持。注意到提干中说interest on this debt is then a significant fixed cost，那么利息＝cost，所以如果c条件满足，cost较低，那么就可以有利可图了。不过总的来看这道题有点含糊，还是认为a也有一定道理，因为a只是说can be...，是一种可能性，不能轻易排除。
