问题 Drugs normally effective in developed countries may not be as effective in the patients in poor countries, because they suffer from other diseases as well.
选项 A、正确
B、错误
答案 A
解析 文章里说：Another example is drugs that are normally effective in suppressing HIV．In poor countries，these might not work in patients who also suffer from malaria，tuberculosis or bad nutrition．也就是说，在发达国家普遍有效的药物在贫穷国家不一定管用，因为那里的人同时患有其他疾病，故True。
