If the statements above are true, which of the following must also be true on the basis of them?
A During the 1980's in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish. 批发商鱼和家禽的利润怎么样，没有提到
B For people who immigrated to Jurania during the 1980's, fish was less likely to be a major part of their diet than was poultry. 对于移民过来的人来说，和家禽相比，鱼渐渐地不是它们的主食了，没说
C In 1989 Juranians consumed twice as much poultry as fish. 89年消耗的家禽是鱼的两倍。单位一不同
D For a significant proportion of Jurania's population, both fish and poultry products were a regular part of their diet during the 1980's. 对于大部分人来说，鱼和家禽仍然是它们的主要食物，没说
E Per capita consumption of fish in Jurania was lower in 1989 than in 1980. 人均鱼的消费量89年比80年低。（1+9%）/（1+6%）=1.028>1
A.说的是profit 的问题，只从消费量增加百分比的信息，是得不出profit 的，不选
B。原文也没有信息去比较 fish and poultry 谁是饮食结构的主要部分，原文知识单纯的阐述，它们俩的消费量增加的百分比
C。因为没有给出消费量本身的数据，所以无法得出一个消费量是另一个的两倍
D。原文知识说fish and poultry的消费量增加了，是无法推出 他们是饮食结构的主要成分。 例如， 这个月我对KFC翅桶的消费量增多了一个百分比，不能说 KFC 就是我饮食结构的主要部分吧， 我每天还是得靠吃米过日子。
E X 为 fish 的1980年消费量，Y 为1980年的人口， 人均 便是X/Y, 那么现在 则是 1.045X/1.06Y, 首先这俩个比值是不等的，其次， 后者变小了。所以选E
