<em>The correct answer is B. Allowing the farmers to buy the land they farmed</em>.
After World War II, the Americans established democratic reforms in addition to economic reforms in Japan. Before the war, Japanese farmers rented almost two-thirds of the land. They did not own the land, they worked for landlords who paid them barely half of the crops they grew. Peasants were poor people.
The American reform hanged this. They took the land away from landlords and redistributed it to the Japanese farmers, so they could own their portion of land. There also were reforms in the industrial sector allowing free trade unions.
Jim Crow laws mandated racial segregation in all public facilities in the states of the former Confederate States of America and in some others, beginning in the 1870s.
They restricted public use of "white only" Resturants, water fountains, theatres and bathrooms. Many more.
