问题 ARVs haven’t been used widely to prevent HIV transmission or infection for lack of money.
Dr. Peter Diot believes that it may be effective to use ARVs to ______.
选项
答案protect partners from AIDS
解析 本题需锁定文章第八段。本段介绍了一组将ARVs用于防止艾滋病传播的试验，目的是为了证明using ARVs before exposure to HIV may have the same effect in protecting partners。 Dr．Peter Diot显然支持这种推测，根据题干语法要求应将原文中的动名词protecting转换为动词原形 protect。
