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.
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.


Of the countries that were the world's twenty largest exporters in 1953, four had the same share of total world exports in 1984 as in 1953. These countries can therefore serve as models for those countries that wish to keep their share of the global export trade stable over the years.

Which of the following, if true, casts the most serious doubt on the suitability of those four countries as models in the sense described?

A) Many countries wish to increase their share of world export trade, not just keep it stable.
B) Many countries are less concerned with exports alone than with the balance between exports and imports.
C) With respect to the mix of products each exports, the four countries are very different from each other.
D) Of the four countries, two had a much larger, and two had a much smaller, share of total world exports in 1970 than in 1984.
E) The exports of the four countries range from 15 percent to 75 percent of the total national output.

Here Answer is

For the first question... I used process of elimination..... If you read the choices A, B, D, E, taken their form to be true, each option objects to interpret rank on these lists as one of the indices of the quality of hospital care.... C is the only option which is restating the facts mentioned in the stem....
To offer additional support,
A- Directly stated that rank order is a false indication/representation. Eliminate
B- States that (some) hospitals discharge patients early so that they don't die in the hospital (instead they die at home). So the rank which considers deaths only at hospitals is unrepresentative. Eliminate
C- Older patients are more likely to die compared to younger patients for a given condition. Well fine, the stem mentions that "data has been adjusted to accommodate age differences of patients". So what new information did this option provide? I feel this option is a lite strengthener because by stating so, it is supporting the act of considering patient age difference while giving ranks mentioned in the stimulus. Not objecting, a contender. Keep.
D- Hospitals have challenging cases to treat. So because some hospitals are taking challenging cases and being unsuccessful doesn't mean that they provide less quality service. This option is providing an alternate cause to the seen effect (deaths are not because of quality of service but because of challenging cases). Eliminate.
E- On the same lines of option D. Rather than taking up challenging cases, hospitals are referring them to other hospitals. So other hospitals death statistics get screwed because they are taking up challenging cases but the hospitals which refer the patients show less deaths and so good ranks. Moreover, this option states that hospitals which doesn't have quality equipment (or quality service) refer them to other hospitals and so lesser quality hospitals still have lower deaths. So ranking system will not work. Eliminate.

Only contender C
