问题 VARIATION IN THE AMOUNT OF CAFFEINE IN COMMON BEVERAGES AND DRUGS*

*Based on 5-ounce cups of coffee, tea, and cocoa; 12-ounce cups of soft drinks; and single doses of drugs.
Which of the following shows the four types of coffee listed in order according to the range of the amounts of caffeine in a 5-ounce cup, from the least range to the greatest range?
选项 A、Decaffeinated, instant, percolated, drip-brewed
B、Decaffeinated, instant, drip-brewed, percolated
C、Instant, decaffeinated, drip-brewed, percolated
D、Instant, drip-brewed, decaffeinated, percolated
E、Instant, percolated, drip-brewed, decaffeinated
答案B
解析 For each of the four types of coffee, the range of the amounts of caffeine is the greatest possible amount minus the least possible amount. In the graph, this difference is represented by the length of the corresponding bar, so you can order the four types of coffee according to the lengths of their corresponding bars, from shortest to longest. From the graph, you can see that the order is decaffeinated coffee, instant coffee, drip-brewed coffee, percolated coffee. The correct answer is Choice B.
