Problem: Extract the answer to the question from the following context. Question: What did they use to defend key cities? Context: Yet controlling the "Mandate of Heaven" was a daunting task. The vastness of China's territory meant that there were only enough banner troops to garrison key cities forming the backbone of a defense network that relied heavily on surrendered Ming soldiers. In addition, three surrendered Ming generals were singled out for their contributions to the establishment of the Qing dynasty, ennobled as feudal princes (藩王), and given governorships over vast territories in Southern China. The chief of these was Wu Sangui, who was given the provinces of Yunnan and Guizhou, while generals Shang Kexi and Geng Jingzhong were given Guangdong and Fujian provinces respectively.

Problem: Extract the answer to the question from the following context. Question: Were there more residence living in Florida in 2010 with an African ancestry or Jamaican ancestry? Context: As of 2010, those of African ancestry accounted for 16.0% of Florida's population, which includes African Americans. Out of the 16.0%, 4.0% (741,879) were West Indian or Afro-Caribbean American. During the early 1900s, black people made up nearly half of the state's population. In response to segregation, disfranchisement and agricultural depression, many African Americans migrated from Florida to northern cities in the Great Migration, in waves from 1910 to 1940, and again starting in the later 1940s. They moved for jobs, better education for their children and the chance to vote and participate in society. By 1960 the proportion of African Americans in the state had declined to 18%. Conversely large numbers of northern whites moved to the state.[citation needed] Today, large concentrations of black residents can be found in northern and central Florida. Aside from blacks descended from African slaves brought to the US south, there are also large numbers of blacks of West Indian, recent African, and Afro-Latino immigrant origins, especially in the Miami/South Florida area. In 2010, Florida had the highest percentage of West Indians in the United States, with 2.0% (378,926) from Haitian ancestry, and 1.3% (236,950) Jamaican. All other (non-Hispanic) Caribbean nations were well below 0.1% of Florida residents.
