Who were against the eugenics program? why did they claim it was a false science?

In 1910, an equilibrium model was created by Godfrey N. Hardy and Wilhelm Weinberg, which disproved claims from the Eugenics program, developed by Francis Galton in the early 1900's, that low-class families were "tainting" the gene pool with dysgenic genes.

Later in 1935, the Carnegie Institution disproved the majority of the Eugenics Record Office's work of any scientific merit based on the works of scientists such as George Shull, who showed that hybrid organisms were more vigorous than pure-breed ones, thus discrediting racial purity as biological superiority.

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.
