gwd第四套的第8题

8:

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.可是我觉得还是有点不严谨.

文中说从1980到1989消费鱼的量增长4.5.人口增长6.但文中没有提到是增长是保持一个增长率从1980到1989.文中说的是从1980到1989总共增长,完全有可能在1980时人口增长5.9而鱼的消费只增长0.1.而在89时人口增长为0.1而鱼却增长4.4这样是不是e就不成立了?是不是把e改成Per capita consumption of fish in Jurania was lower in 1990 than in 1979比较合理?
