Q29
From 1985 to 1994, what was the percent increase in total United States trade?
(1)Total United States trade in 1985 was 17 percent of gross domestic product in 1985.
(2)Total United States trade in 1994 was 23 percent of gross domestic product in 1994.

Ans : E

我的想法 : 不是直接算17% 到 23%的成長幅度就是答案了嗎??

嗯...看到比例或是百分比就聯想到總數的概念考題....
假設1985總毛利一百億，則17%就是17億，
1994總毛利是一兆，則23%就是2300億....
也就是說，題目並沒有告知條件總毛利從1985到1994是不變的，故無法得知。
