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?

1. 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.
   
   

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.

In 1989 Juranians consumed twice as much poultry as fish.

For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.

Per capita consumption of fish in Jurania was lower in 1989 than in 1980.

答案是E
但是为什么per capita consumption of fish会lower in 1989 than in 1980呢？
因为consumption of fish increase by4.5% , 而人增长了6%？
为什么B 和D 不行呢？
求解答 谢谢！

B：也许不是因为移民的口味偏好啊，也可能是什么环境污染啊导致的fish少了啊什么的
D：跟题干完全无关啊...
