question:
Passage: Claiming the right to name his discovery, Le Verrier quickly proposed the name Neptune for this new planet, though falsely stating that this had been officially approved by the French Bureau des Longitudes. In October, he sought to name the planet Le Verrier, after himself, and he had loyal support in this from the observatory director, François Arago. This suggestion met with stiff resistance outside France. French almanacs quickly reintroduced the name Herschel for Uranus, after that planet's discoverer Sir William Herschel, and Leverrier for the new planet.
answer:
What name was opposed by the french?


question:
Passage: African Americans made up 41 percent of death row inmates while making up only 12.6 percent of the general population. (They have made up 34 percent of those actually executed since 1976.) However, that number is lower than that of prison inmates, which is 47 percent. According to the US Department of Justice, African Americans accounted for 52.5% of homicide offenders from 1980 to 2008, with whites 45.3% and Native Americans and Asians 2.2%. This means African Americans are less likely to be executed on a per capita basis. However, according to a 2003 Amnesty International report, blacks and whites were the victims of murder in almost equal numbers, yet 80 percent of the people executed since 1977 were convicted of murders involving white victims. 13.5% of death row inmates are of Hispanic or Latino descent, while they make up 17.4% of the general population.
answer:

What percentage of American death row prisoners are South American
