问题 Which of the following best states the main idea of the passage?
Fevers cause ______.
选项 A、prostaglandins to be formed
B、iron to be made available to bacteria
C、leukocytes to be more mobile
D、lizards to be cold-blooded animals
答案C
解析 本题是道细节题。本题答案选择C项是根据文章最后一段中Leukocytes,white blood cells that ale active in fighting bacterial infections are more mobile at febrile temperature.(积极参与抵抗细菌入侵的白血球在高温下更加活跃。)而作出的，A项和B项的叙述与文章不相符，而D项虽是正确的表述，但与本题毫不相关，因此要舍弃。
