问题 ARVs haven’t been used widely to prevent HIV transmission or infection for lack of money. [br] According to Ramjee, the combination of ________________ is possibly the most effective in preventing HIV virus from transmitting during intercourse.
选项
答案 microbicides and ARVs
解析 本题定位信息是Ramjee 和combination，从而锁定文章第六段。该段最后两句提到At best，microbicides may be 80% effective in preventing the transmission of the virus during intercourse．To improve the chances that the virus doesn’t slip by，however，there is always the possibility of combining the ARVs…。由此可知，防止HIV病毒传播的最有效的方式是将microbicides和ARVs结合使用。故本题应填入 microbicides and ARVs。
