(i) The statement is False. Education has both private and social returns. The social benefits of education include enhanced employment oppurtunity and incomes, improved social skills, status and networks etc. Hence education has positive externality. If government does not intervene then a lesser number of people will be educated acoording to the marginal private benefits. When marginal social benefit would be considered, a higher number of people will be educated in the social optimum. Hence government intervention is important so that the externality can be internalized and more people get educated.
(ii) False. Public goods cannot be provided by a private entity. A private entity will seek profits. As is the nature of public goods, there is no scope for profits. Hence government must provide public goods by taking into consideration the marginal social benefits.
(iii) The statement is true and is related to one of the basic principles of economics. To understand why this is true, consider the e.g. of taxation. If every individual of an economy were taxed the same regardless of their incomes, this may be a simple and efficient way but is not equitable. Equity here would mean that individuals who value economic resources highly (generally high income people) should be ones to pay more taxes. This way there will be less burden (or even no burdens) on people with low incomes (or extremely low incomes). From this example we can see that trade offs always exist in our world.
(iv) This stattement is true. Adverse selection occurs due to asymmetric information in the market. This means one party (generally the seller) has more information about the product than the buyer. This incentivizes the seller to charge a higher market price for his product and earn higher profits. Another e.g would be for insurances where people working in hazardous conditions (like risking) buy insurances. Here buyers have more information. There knowledge of high risk to their lifes incentivezes them to buy insurances. Hence statement is true.
