The transportation department plans to build a new high-speed train route between two cities. The transportation department wants to implement a simulation of the train before any construction begins on this project. Which of the following statements is true about the use of a simulation for this project? a. A simulation cannot be used to test the train under varying weather conditions.
b. Implementing a simulation is likely to increase the overall costs associated with the project.
c. Other high-speed train routes have been constructed in other locations, so a simulation is not needed.
d. Using a simulation may expose potential safety issues that can be corrected before construction begins.
