Although the ratio of physicians to total population is about the same in the United States and Canada, the United States has 33 percent more surgeons per capita. Clearly, this is the reason people in the United States undergo 40 percent more operations per capita than do Canadians.
The explanation given above rests on an assumption that:
A). patients in the United States do not have a greater need for surgery than do    patients in Canada
B). the population of the United States is not larger than that of Canada
C).United States patients sometimes travel to Canada for certain kinds of surgery
D).general practitioners in the United States do not as a rule examine a patient who is a candidate for surgery before sending the patient to a surgery
E). there are no unnecessary surgical operations performed in Canada

Agree with upstairs!
The correct answer is A!

In my view , the arguer reasons that because people in the United States undergo 40 percent more operations per capita than do Canadians,the United States has 33 percent more surgeons per capita even though the ratio of physicians to total population is about the same in the United States and Canada.

But the contradictory of A  asserts that the reason of the fact that the United States has 33 percent more surgeons per capita is more  becasue patients in the United States have a greater need for surgery than do patients in Canada than because  people in the United States undergo 40 percent more operations per capita.Obviously , the contradictory of A seriously undermine the explanation of the arguers. So A is the sound assumption.
In other words, A rule out other alternative explanation.

Welcome to dispute my opinion.
