同志们~~~~~~ 楼主说的那道逻辑题我在GWD上看见过,下面就奉上原题~~~~ 大家努力~~发奋为大家提供资料觉得很幸福~~字体很奇怪,请大家凑合着看吧 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?
