A.Y
B.N
C.NG
参考答案
正确答案:C
解析:本题定位信息是the developing countries,从而将答案出处定位到文章第三段。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,故答案为NG。
