A public good is an example of a good or product that individuals can consume or use without reducing its total availability for others. Goods like national security, sewer systems, public parks, among others, are considered as public goods. Many can benefit from it and it is considered by economists as goods that are "non-rivalrous" or "non-exclusive." <span>

Answer: a. The patent is an intangible so it is amortized for cost recovery
Explanation:
Just as Depreciation exists for the wearing and tearing of tangible Assets, so does AMORTIZATION exist for Intangible Assets like goodwill, patents, licenses, copyrights and logos. 
 It follows essentially the same process as Depreciation and the useful life estimation is usually discretionary because some Intangible Assets can give benefits forever such as logos. 
Generally though, only Intangible Assets with estimable useful lives are amortized such as Patents and Trademarks.

Answer:
A) Economies of scale
Explanation:
Producing natural gas is very expensive and requires a large investment. The costs and risks of the processes involved in the upstream and downstream of natural gas discourage competition. Besides requiring a large initial investment, a drilling company can never be 100% sure that they will be able to find and extract natural gas or petroleum. So besides having to spend a lot of money, you are assuming a great risk. 
Even if a competitor finds natural gas, in order for the downstream process to be profitable, they must be able to extract a large volume to achieve economies of scale.
