标题: 求GWD4---8
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E中,1989的比例应该为1980的乘上1.045/1.06吧。至于B,只出现百分比,不可能比出多少来。。。

B选项,说在那年,因为鱼的 总消费量 下降了,推出那些 移民过来的人 不爱吃鱼
这之间有个GAP 就是没有讨论原住民的食品取向
如果移民过来的人只有一个人,他巨爱吃鱼,但是原住民都不爱吃鱼,那鱼的总消费量还是下降
所以B不对
注意,总消费量 一定对应 总人口。
