解析 The correct answer is A. According to the graphs, from 1990 to 2000, the average number of production hours per widget decreased from 9 to 5. To calculate the percent decrease, divide the difference between the starting value and ending value(9-5)by the starting value: 4/9 = 0.44 , which is equivalent to 44%.
