单选题 The reason for the government's expansion program working not so well is______

A、 because the farmers were uncertain about the financial support the government guaranteed
B、 because the farmers were uncertain about the benefits of expanding production
C、 because the farmers were uncertain whether foreign markets could be found for their produce
D、 because the older generation of farmers were strongly against the program

【正确答案】 B

【答案解析】第五段第三、四句指出，尽管有当前价格和市场的保证，农民们害怕他们受到进口低价食品和收缩的国内市场的挤压。当前生产以高于战前51%的水平进行，而政府号召到1956年扩展到60%；然而政府反复的忠告没有太大影响，扩展计划进行得并不顺利。
