大全GMAT-Test 14-12

12.   Although
aspirin has been proven to eliminate moderate fever associated with some
illnesses, many doctors no longer routinely recommend its use for this purpose.
A moderate fever stimulates the activity of the body’s disease-fighting white
blood cells and also inhibits the growth of many strains of disease-causing
bacteria.

If the statements above are true, which of the following
conclusions is most strongly supported by them?

(B) Aspirin can prolong a
patient’s illness by eliminating moderate fever helpful in fighting some
diseases.

an:B

题目为归纳，那么根据原题，只能推出因为aspirin影响了moderate fever，而moderate fever影响了the activity of the body’s disease-fighting white
blood cells and also inhibits the growth of many strains of disease-causing
bacteria.

那么，就是aspirin影响了the activity of the body’s disease-fighting white
blood cells and also inhibits the growth of many strains of disease-causing
bacteria.

答案中的prolong怎么理解呢？我觉得原题中推不出啊？

原题又没有说，没有了moderate fever的刺激，就会延长疾病啊？

请指教
