Final answer:
The list that only includes capital resources is 'Autos owned by a car rental firm; computers at the car rental agency; the vans that shuttle rental customers to and from the airport.' These are all physical capital, substantial resources used by businesses to provide their services.
Step-by-step explanation:
The question is asking to choose the list that only includes capital resources and doesn't contain any labor or land resources. In economics, the term capital refers to physical assets that help in the production process, and they can be intangible - like a brand's reputation, or tangible - like machinery, equipment, or buildings.
Among the given options, the list that includes only capital resources is: 'Autos owned by a car rental firm; computers at the car rental agency; the vans that shuttle rental customers to and from the airport.' These are all physical capital resources used by businesses to deliver their services. In contrast, items like a professional hockey player or the owner of a startup firm represents labor, not capital. Similarly, the water behind a dam is more of a natural resource with regards to economics, typically categorized under land.
