问题 ARVs haven’t been used widely to prevent HIV transmission or infection for lack of money.
Lack of prevention strategies and treatment programs makes the developing countries the largest in the number of HIV infection.

选项 A、Y
B、N
C、NG

答案C

解析 本题定位信息是the developing countries,从而锁定文章第三段。该段第二句提到And yet…have not really taken hold in the developing nations where the rate of infection is highest。由此可知prevention strategies 和 treatment programs的缺乏使发展中国家感染AIDS的比例最高,但文中并没有提到人数最多。故题干中的the largest in the number在文中找不到依据,答案为NG。
