Wow hahahah....我終於已經冒兩把火了...再接再力 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?

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.


Can anyone explain why the answer is E ? I choose B *-)

說說個人想法...多指教

b其實並不能從題目推得...
因為題目只說j第人口增加部分來自移民...
但完全沒提移民愛吃什麼...
可能愛吃魚...也可能愛吃肉...
因此不能推得
舉例來說,可能魚上升的4.5%全部都是移民吃的....
那這樣的話b不就錯了嗎..

再來看e...
移民增加6%....但是吃魚量才增加4.5%
所以e所言每個人吃魚的量一定會下降...
正確答案...
