一道蓝皮结论题，大家帮忙啊！

  although aspirin has been proven to eliminate moderate fever associated with some illness, many doctors no longer routinely recommend its use fo r this purpose. A mederate fever stimulates the activity of the body's disease-fighting white blood cells and also inhibits the growth of many strain of disease-causing bacteria.

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

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

(C) Aspirin inhibits the growth of the white blood cells, which are necessary for fighting some illness.

请问B，C应该选哪一个？这道题应该怎么思考？谢谢！

B 

因为：

1。aspirin 是阻碍了fever，而不是white blood cells (尽管有间接作用）

2。fever 可以阻止其他病，而不是white blood cells阻止其他病。
