E的解释应该不存在明显的flaw,但是与题目结论的逻辑关系不是很直接,结论强掉widespread vaccination of children,所以因寻找与chidren有关的选项,如果如D中所说,Adults do not contract influenza from children,那么这个assumption与conclusion具有更密切的逻辑联系。
D选项指adults因接触已感冒的小孩而得感冒,那么不是与原文中“Adults are commonly vaccinated”矛盾吗?D选项是否改为“ D. Adults are not at risk of serious complications from influenza resulting primarily from children who have influenza.”较好?
