1. As the price of a good rises, the quantity required is reduced.
2. The situation in low-income countries has improved since 1965.
3. The problem of maximum rates is to reduce the price for consumers, and task minimal rates is to raise the price for producers and suppliers.
4. The increase in supply leads to an increase in equilibrium quantity and a decrease in equilibrium price.
5. When rates will be reduced to the equilibrium price, there will be surplus goods.
6. If the price of a commodity falls, and prices of other goods required by the customer, remain the same, then the consumer will buy cheaper products instead of expensive goods.

Junk food has for a long time been eaten by people.  It is considered easy to get and cheap to buy.  Lots of commerciasl every day are broadcast  on the radio and TV. 
I strongly believe that advertizing junk  and unhealthy food should be prohibited.  Doctors say that junk food leads to obesity and serious diseases.  Children like it because it looks nice and smells nice.  But they are not aware of the danger. 
Some people may think that such a ban on junk food advertisement is a  violation of rights.  It also poses danger to freedom of speech and mass media, they may think. 
But I consider that our nation's health is more important.  So we must do all we can to teach people to choose healthy food for themselves and their children. Results of scientific research in this field should be made public.  So the people will  finally make the right choice!
