Passage Summary: One hospital keeps people for four days while another keeps them for six, but patients get better at the same rate. So, the second hospital is just wasting time and could send people home sooner.

Conclusion: University Hospital could reduce its average patient stay length without lowering the quality of care.

Reasoning: Edgewater Hospital has a shorter average stay than University Hospital, yet both have similar recovery rates for similar illnesses.

Analysis: The argument assumes that because the illnesses are 'similar,' the patients and their needs are also identical. This ignores the possibility that University Hospital might treat a more vulnerable population—perhaps older patients or those with fewer resources at home—who require those extra two days for a safe recovery. Look for an answer that identifies this failure to consider relevant differences between the two hospitals' patient bases. Just because the 'illness' is the same doesn't mean the 'patient' is.
