单项选择题
What happened to Jamaica’s sugar factories in the 1990s
A．They witnessed unsuccessful reforms.
B．They went bankrupt due to crop failure.
C．They suffered from inefficient production.
D．They failed due to a shortage of labor supply.
答案
参考答案：A
解析：事实细节的找寻和判断。根据题干信息找到相关的原文第二段第四、五句发现，该国对制糖业改革以后，结果是天灾(洪水和干旱使糖作物面临灾难)、人祸(工厂倒闭会使工人暴动)，由此可判断，该国的改革并不成功。因此，选项a的内容符合题意，是正确答案。 注意：正确对原文关键词进行总结，如将原文floods and droughts， disaster，shutdown，riots等词可总结为unsuccessful reform。
