问题 ARVs haven’t been used widely to prevent HIV transmission or infection for lack of money. [br] Zeda Rosenberg has an assumption that the latest microbicides don’t cause many side effects by reason that the body system ______.
选项
答案 absorbs few
解析 本题需锁定文章第六段。该段第二、三句提到：“The studies so far，with most of the ARV products，suggest very low levels of systemic absorption，”she says．“It may be that there is insufficient absorption to select for resistance。由此可知，大多数microbicides没有引起身体的resistance的一个可能原因是 very low levels of systemic absorption，这里的systemic指的就是身体系统。根据题干语法要求，这里应填入一个动宾短语，故应将absorption转化为动词形式的absorb，并使用第三人称单数，故答案为absorbs few。
