120. 鱼，猪肉和移民
【原题- -】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?
A. 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.
B. 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.
C. In 1989 Juranians consumed twice as much poultry as fish.
D. For a significant proportion of Jurania’s population, both fish and
poultry products were a regular part of their diet during the 1980’s.
E. Per capita consumption of fish in Jurania was lower in 1989 than in
1980.
B答案有什么问题啊，它说对于80年代移民去的人，鱼相对于家禽不大可能是他们的主食，我觉得这个没问题啊，题意表面了这些人比土著人吃家禽比吃鱼多。我们都不知道他们的主食到底是什么，但是less likely to be 不就说的一种可能性吗？

题目问must be true，B选项只是一种可能性，不一定为真。
题干说的都是比例，没有给基数，因此得不出【吃家禽比吃鱼多】这个结论
比如，人们可以还是更喜欢吃鱼，原来鱼的消耗量是100 million，增长4%，就是增长4million
而原来家禽的消耗量是1million的话，B选项就不成立了
