Answer:
is available to all and cannot be denied to anyone.
Step-by-step explanation:
Public goods are both nonexcludable and nonrivalrous. This means that everyone is entitled to use them and when someone is using them it doesn't mean others can't use them at the same time. Of course there is always a limit to the capacity of their use, like roads can only be used by certain amount of cars.
For this particular characteristic of public goods is that private firms don't offer them. Private firms' main concern is making the largest possible profit and public goods usually aren't profitable. That is why the government has to provide public goods since no one else will.
