Because most hospitals suffer a chronic undersupply of physicians, patients must sometimes
wait hours in the emergency room to see a doctor. Nurses should therefore perform initial
examinations in hospital emergency rooms to determine which patients merit immediate
treatment and which can wait until the emergency physicians have more time to see them.
Which of the following is an assumption on which the argument above is based?
A) Hospitals should expand their medical staffs.
b) Physicians cannot be trained to perform initial examinations themselves.
c) Emergency rooms will run more smoothly if initial examinations are performed.
d) Hospitals are always fully staffed with nurses.
e) Nurses are competent to judge the severity of patients’ conditions.

right ans clearly boils down to D or E
By negating option D=> Hospitals are not always fully staffed with nurses.
This means that in a given series of discrete days there is a possibility that in one, or more, or all days the nurses are not fully staffed, but it does not necessarily mean that they are always understaffed. It sure does affect the argument to a certain extent, but lesser than the impact caused by negating E.
By negating E=> The nurses are not competant to judge the severity of the patient's condition.
This totally nullifies the conclusion, suggesting the possibility that there will be instances where low priority patients are attended to prior to critical cases.
Now weigh the impacts of negating D & E and you will see negating E does more damage to the conclusion
