A．the body loses oxygen and other organs fail
B．a sodden mass of dying tissues
C．the enthusiastic immune systems of the young
D．the overreaction of blood, toxic fluid, and rampaging inflammatory cells此题为多项选择题。请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：C
解析：本题考查考生的理解能力，关于禽流感感染年轻力壮的人群的原因，文章在第三段第一句提到This vulnerability may stem from the robust and fast-responding immune systems of the young(这个弱点可能来自于年轻人健全又敏感的免疫系统)，从这里我们可以看出年轻人充满活力的免疫系统是他们感染禽流感的主要原因，所以C项符合题意。
