Question

what is the merit and demerit answer ...??

Answer 1

Merit goods are 'good' for you. Demerit goods are thought to be 'bad' for you. Examples are alcohol, cigarettes and various drugs. In this case the market fails because these goods are over-consumed if left to the free market. Again, the government must step in to stop this over-consumption.

A demerit is also a fault or weakness.

If you're trying to decide which candidate to vote for, consider the merits and demerits of each.

The other kind of demerit is a punishment — a negative mark against someone, especially a student or a member of the military
