Q32:GWD-4-8

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.

我怎么觉得B是对的呢, 移民增长率高于FISH而低于POULTRY的增长率, 只能说明移民消耗POULTRY类的量比FISH多啊. 但E也是没什么毛病,晕. 哪位能解释得清楚些啊.

B是存在问题的，如果，存在这么个假设，移民既不吃ＦＩＳＨ也不吃POULTRY＜既两种食物都是由本地居民消耗的＞，又怎么能得出移民消耗POULTRY类的量比FISH多呢．

E   他们可能主食都是猪肉PORK 或者 BEEF  或者 CORN 啊 ！   没有说major part of their diet  是  鱼肉或者禽肉

B can't be ture.

Since we don'y know the absolut value of the consumption of fish and that of the poultry.

The increase precentage means nothing if the consumption of poultry is far more bigger than that of fish. And at that moment, B has been weakened.

E: Just like an quantitive question to answer

1980: Consumption of fish X         ||  population Y

per capita of fish = X/Y =1.06X/1.06Y-----A

1989: Consumption of fish 1.045 X   ||  population 1.06Y

per capita of fish = 1.045 X/1.06Y--------B

B is smallar than A
