gre argument 79题目：

The following appeared in a magazine for the trucking industry.

"The Longhaul trucking company was concerned that its annual accident rate (the number of accidents per mile driven) was too high. It granted a significant pay increase to its drivers and increased its training standards. It also put strict limits on the number of hours per week each driver could drive. The following year, its trucks were involved in half the number(2) of accidents as before the changes were implemented(1). A survey of other trucking companies found that the highest-paid drivers were the least likely to have had an accident(3). Therefore, trucking companies wishing to reduce their accident rate can do so simply by raising their drivers' pay and limiting the overall number of hours they drive(4,5)."

提纲：

(1)Other possible factors could also lead to the decline in the number of accidents of Longhaul.

(2)The author fails to provide the annual accident rate of Longhual after the changes were implemented. (or) The author does not inform us the total mileage driven at Longhaul in that year.

(3)The author fails to rule out the possibility that those highest-paid drivers earn high salary just because they are safe drivers.

(4)Adopting the author’s proposal alone may not sufficiently reduce the accident rates.

(5)Other methods could also be used to achieve the same purpose.
