Q8:

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.
   
2. 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.
   
3. In 1989 Juranians consumed twice as much poultry as fish.
   
4. For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.
   
5. Per capita consumption of fish in Jurania was lower in 1989 than in 1980.

答案是E，可是我怎末觉得B也正确呢

从题中看出人口增长6%，而鱼消费量增长4。5%，禽消费量增长9%，便可以知道增加的这些人中鱼消费小于禽消费，由此可得B选项阿

哪位给解释解释？谢谢

无法从题中得出：本地人对鱼消费的变化，这个量不定，B就无法得出
