Notice 2 Beginning next month, the city will institute a program intended to remove graffiti from city owned delivery trucks. Any truck that finishes its assigned route before the end of the driver’s shift will return to its lot where supervisors will pro vide materials for that driver to use while clean ing the truck. Because the length of time it takes to complete different tasks and routes vary, trucks within the same department will no longer be assigned to specific routes but will be rotated among the routes. Therefore, drivers should no longer leave personal items in the trucks, because they will not necessarily be driving the same truck each day, as they did in the past.According to the passage, routes within partic ular departments a. vary in the amount of time they take to complete. b. vary in the amount of graffiti they are likely to have on them. c. are all approximately of equal length. d. vary according to the truck’s driver.
