Answer:
public
Step-by-step explanation:
There is no free education, because all kinds of educational institutions, even public ones, are paid by citizens' taxes. For public universities, the funding given to them is provided through state sales taxes and state taxes. That is, all rich or poor citizens when they pay their taxes are in some way contributing to the funding of public universities. The same is true when the state makes a sale, the profit from that sale also helps to finance these universities.
