Based on the following selection, what can be determined about the regulations for railcar bulk-cargo transportation? Many railroads end at coastlines where goods are placed on shipping barges without ever leaving the rail cars. In these cases, the separation regulations hold, but the regulation falls under another federal agency.
Answer
A
They are updated each year as new modes of transportation are added.
B
They are utilized only when hazardous materials are not being transported.
C
They are appropriate for any mode of transportation.
D
They are specific to only one mode of transportation.
Explanation
The selection says that when railcars are loaded onto shipping barges, the separation regulations still apply, but they fall under a different federal agency. This shows the rules depend on the mode of transportation and which agency regulates it. Therefore, the regulations are specific to only one mode of transportation, rather than automatically applying to every mode.
