1)(C) Oligopoly and monopoly

There are barriers that prevent new firms from entering oligopolies and monopolies, resulting in few (oligopoly) or one (monopoly) firms. In monopolistic competition and perfect competition, on the other hand, there are limited barriers to entry, resulting in many firms in both market types.

2)The correct answer is a. there are substantial startup costs and other barriers to entry.

This is the correct answer because of the presence of certain production cost. The monopolist has to keep the price of the initial unit at a low level to gain the market share. This strategy would lead to attracting consumers in the market. For the further units to be sold, the monopolist would improve the price level, where the marginal revenue would be equal to the marginal cost.

3)The provision of an education in public school is (D) Nonexclusive and non-rival. Public school is nonexclusive (also know as non-excludable) because any student can attend without needing to pay for it. Additionally, it is non-rival because one student attending does not prevent another student from attending since public schools must accept all students. Therefore, public schools are a public good.
