问题 ARVs haven’t been used widely to prevent HIV transmission or infection for lack of money. [br] Widely using PrEPs may cause potential problems like ethical issues and ________________.
选项
答案 resistance
解析 本题定位信息是potential problems，从而锁定文章最后一段。该段第一句首先提到Piot， however，notes that if PrEPs prove effective，they will create a number of thorny ethical issues；该段中间又提到Resistance is a key issue with PrEP as well，指出了广泛使用PrEPs可能引起的另一个问题，故本题应填入 resistance。
