Deng xiaoping believed that the standard of living in china could be improved by reducing population growth increasing population growth allowing farmers to have large families moving people from the crowded eastern coast

Correct  reducing population growth

Deng Xiaoping rose to power in China in the years following the death of Mao Zedong in 1976.  Mao had opposed the idea of controlling population growth in China, saying, "The more people there are, the stronger we are."  But Deng started a new policy in China in 1979, the "one child policy."  Under the policy, most Chinese families were restricted to having only one child. Incentives for jobs and financial advantage were in place for those who complied with the policy, and sometimes harsh measures such as sterilizations and abortions were implemented during the years that the policy remained in force.

When originally begun by Deng, the one-child policy had the goal of restricting population growth so that it did not go faster than China's  economic development was able to support.

for the 2 countries u can do china and america because america has a democratic government while china has a communist government.

a democracy is a government run by the people either by directly voting or indirectly by electing representatives. an oligarchy is a government run by a few or a small group of people. a democracy and oligarchy are similar because both in an oligarchy and an indirect democracy, a small group of induvial determine the laws for a large group of people they are different because in an oligarchy it is easier to control and they do not have to answer to a large number of people in the country, unlike a democracy where they do have to answer to a large number of people an county that is a democracy would be the united states. a country that is an oligarchy would be the china.
