选项
答案 absorbs few
解析 本题定位信息是Zeda Rosenberg，从而锁定文章第六段。该段第二句和第三句提到"The studies so far，with must 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，且动词应用第三人称单数，故答案为absorbs few。
