From 1980 to 1989, total consumption of fish in the country of Jurania increased by 4.5 percent, and total consumption of poultry products there increased by 9.0 percent. During the same period, the population of Jurania increased by 6 percent, in part due to immigration to Jurania from other countries in the region.

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.
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.
C. In 1989 Juranians consumed twice as much poultry as fish.
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.
E. Per capita consumption of fish in Jurania was lower in 1989 than in 1980.

我觉得选B,但答案好像是C

这道题貌似选E吧,设1980年人口为a,吃鱼的量为b,个人消费为b/a,1989年为4.5%a/6%b,算下来数字就变小了

答案是e啊,不是c,b不对,因为前面说的是total consumption 有没有单只移民吃的,怎么能推出是移民更倾向于fish呢,c更扯,这只是一个比值,有可能本来当地人不吃鱼,现在就算上涨10%可能也不上原先占50%的牛肉。e说的是人均消耗量,因为人数增加了8%但牛肉的总消耗量却只增加了5%,牛肉增长率赶不上人口增长率,所以人均肯定下降了
