GMAT Critical Reasoning
When there is a high demand for a trucking company's services, more money is spent on vehicle maintenance and safety inspections than at other times. Thus, the rate of truck accidents should be lower when there is high demand for the company's services than when demand is lower and less money is spent on vehicle maintenance and safety inspections.
Which of the following, if true about a truck company when there is a high demand for its services, casts the most serious doubt on the conclusion drawn above?
- A Truck drivers ask for higher pay and better health insurance benefits during periods in which there is a higher workload due to high demand.
- B Management is sometimes forced to send relatively inexperienced drivers on difficult routes at a much higher rate due to the increased demand for trucking services.
- C Truck drivers are less likely to be dismissed from work for inefficient deliveries during periods of high demand than they are at other times.
- D If all drivers within a given division of the trucking company achieve a perfect safety record for an entire quarter, each driver receives a five percent salary increase.
- E Management often decides to trade older trucks in for newer models rather than trying to repair them, and this process is more likely to occur in periods of high demand.
