Q6:

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?

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.

Answer: E why not B?thank you.

对于这类题目，即must be true,我们永远不能假设哪一部分的数量变化可以归咎于哪个主体，就好比B一样，鱼的增长可以归于任意一方或同时两方，因为题目中没有任何这方面的限制条件。
而这类题目往往只有一个相对的比例才是可以确定的，也就像鱼或者是家禽的消耗增长，与人口的增长相比较，这个分别在1980和1989年的比例是可以确定并进行比较的

另外，consumption不等于eating，因此所有与diet有关的选项都可以首先排除
