Verbal
Critics of the use of trucks to transport nuclear power plant waste are mistaken in claiming that transportation of such cargo poses an undue risk over that of other transportation methods. For example, Yardow Prefecture allows trucks with a typical gross weight greater than 80,000 pounds to transport nuclear waste and despite the significant number of such journeys, no incidents or handling safety violations have been recorded. It is clear that considering Yardow’s proven safety record, policymakers should disregard the critics' concerns and allow trucks to transport nuclear power plant waste as necessary.
Which one of the following, if true, most substantially weakens the argument?
A. Transporting nuclear power plant waste by train does not necessarily require trucks to deliver the nuclear waste to a train’s loading depot.
B. The reporting of traffic incidents in Yardow Prefecture was recently transferred to a different regulatory agency.
C. Truck drivers in Yardow Prefecture are required to obtain a specific class of license to drive a truck if the vehicle’s gross weight is greater than 80,000 pounds.
D. The roads used for nuclear waste transport in Yardow Prefecture are restricted to trucks driven by drivers with a certain class of license designated for gross loads exceeding 80,000 pounds, which is over 20,000 pounds greater than the typical gross load.
E. Normal gross truck loads are 60,000 pounds, and for any load greater than 80,000 pounds, two trucks are typically used to transport that load.
