2月27号JJ:

今天考的人实在是多,总有人进进出出. 弄的我脑袋都大了. 没有达到预期的分数, 只能再准备3月考.

这次数学考试只有1题JJ, 而且三分之二的题都是data sufficiency 题. 连GEOMETRY 题也仅仅碰上2道. 基本上文字题较多.

CR:

City Official: At
City Hospital, uninsured patients tend to have
shorter stays and fewer procedures performed than do insured patients,
even though insured patients, on average, have slightly less serious medical
problems at the time of admission to the hospital than uninsured patients
have. Critics of the hospital have concluded that the uninsured patients are mot receiving
proper medical care.
However, this conclusion is almost certainly false.
Careful investigation has recently shown two things: insured patients have much longer stays in
the hospital than necessary, and they tend to have more procedures performed than
are medically necessary.

In the city official’s argument, the two boldface portions play which of the
following roles?
