从MBA官网上下了题库，但是有两道AA没什么思路，求教达人~

1) The following appeared in a proposal from the sheriff of Adams County.
"Last year a course in driver's eduation became a requirement for graduation for all students at the Adams County High School, and the board of education purchased 10 new cars to provide students in the classes with on-the-road driving experience. Nevertheless, the number of teenage drivers involved in traffic accidents here in Adams Conty has increased by 200 percent this year, and officers from the sheriff's department have cited a record high number of teenagers for violations of traffic laws. Since the high school driver's education classes have been so ineffective in improving traffic safety, we should no longer require them and should spend our limited funds on other programs."

2) The following appeared in a budget proposal for the country of Salutopia.
"Over the past 20 years the birth rate in Salutopia has declined. During that same period, however, the number of physicians practicing in Salutopia has steadily increased, and the average number of patients treated by each physician has decreased by 30 percent. Mean while, average life expectancy in Salutopia has risen to 71 years, and the mortality rate fell significantly last year. Since such data indicate dramatic improvements in public health and a more than adequate supply of physicians in Salutopia, the national medical college need not expand and can perhaps evern reduce its size."
