A ten-year comparison between the United States and the Soviet Union in terms of crop yields per acre revealed that when only planted acreage is compared, Soviet yields are equal to 68 percent of United States yields. When total agricultural acreage(planted acreage plus fallow acreage)is compared, however, Soviet yield is 114 percent of United States yield. From the information above, which of the following can be most reliably inferred about United States and Soviet agriculture during the ten-year period?
选项
A、A higher percentage of total agricultural acreage was fallow in the United States than in the Soviet Union.
B、The United States had more fallow acreage than planted acreage.
C、Fewer total acres of available agricultural land were fallow in the Soviet Union than in the United States.
D、The Soviet Union had more planted acreage than fallow acreage.
E、The Soviet Union produced a greater volume of crops than the United States produced.
答案
A
解析
要注意读懂题目,题目所做比较对象是苏联与美国的Crop yields per acre。若用X表示苏联粮食总产量,a表示苏联planted acreage,a’表示苏联fallow acreage,用y表示美国粮食总产量,b表示美国planted acreage,b’表示美国fallow acreage,那么,
。当一个分数的分子不变时,那么分母所增加的比例越小,其值就越大。因此我们由
就可以得出a’在(a+a’)中占的比重一定比b’在(b+b’)中占的比重小,所以(A)正确;(C)、(D)易误选,但仅仅一个数量一般不能说明问题。试体会(C)的一个反例:
,其中X=1000,y=500,a’=100,b’=90。
