A logistics firm plans to reduce fuel expenditures by replacing its fleet of long-haul trucks with new models that are 20% more fuel-efficient per mile. The firm notes that the total number of miles driven across all routes has remained stable for the last five years. Based on this stability, the firm concludes that the replacement will lead to a significant decrease in total annual fuel costs. Which of the following, if true, most strongly supports the firm's conclusion? Argument: A firm intends to cut costs by adopting fuel-efficient trucks, relying on the fact that total mileage has been consistent over a five-year period to predict future savings.

1. The operational characteristics of the new models do not require drivers to undergo significant additional training that would impact delivery schedules.
2. Several of the firm’s competitors have recently announced plans to upgrade their fleets with similar fuel-efficient technology.
3. Fuel prices are projected to decrease slightly over the next fiscal year as global production increases.
4. The routes the firm services are primarily on flat terrain, where the fuel efficiency of the new models is most consistently achieved.
5. The cost of maintaining the older trucks has increased significantly over the last two years due to engine wear.
