Problem: Please answer a question about the following article about Charleston, South Carolina:
In 1875, blacks made up 57% of the city's population, and 73% of Charleston County. With leadership by members of the antebellum free black community, historian Melinda Meeks Hennessy described the community as "unique" in being able to defend themselves without provoking "massive white retaliation", as occurred in numerous other areas during Reconstruction. In the 1876 election cycle, two major riots between black Republicans and white Democrats occurred in the city, in September and the day after the election in November, as well as a violent incident in Cainhoy at an October joint discussion meeting.
The second riot of 1876 happened when?
A: the day after the election in November
Problem: Please answer a question about the following article about Bird:
Some species, including frigatebirds, gulls, and skuas, engage in kleptoparasitism, stealing food items from other birds. Kleptoparasitism is thought to be a supplement to food obtained by hunting, rather than a significant part of any species' diet; a study of great frigatebirds stealing from masked boobies estimated that the frigatebirds stole at most 40% of their food and on average stole only 5%. Other birds are scavengers; some of these, like vultures, are specialised carrion eaters, while others, like gulls, corvids, or other birds of prey, are opportunists.
A vulture is what type of bird?
A: scavengers
Problem: Please answer a question about the following article about Biodiversity:
The control of associated biodiversity is one of the great agricultural challenges that farmers face. On monoculture farms, the approach is generally to eradicate associated diversity using a suite of biologically destructive pesticides, mechanized tools and transgenic engineering techniques, then to rotate crops. Although some polyculture farmers use the same techniques, they also employ integrated pest management strategies as well as strategies that are more labor-intensive, but generally less dependent on capital, biotechnology and energy.
What is one of the great agricultural challenges that farmers face?
A: The control of associated biodiversity
Problem: Please answer a question about the following article about London:
London was the world's largest city from about 1831 to 1925. London's overcrowded conditions led to cholera epidemics, claiming 14,000 lives in 1848, and 6,000 in 1866. Rising traffic congestion led to the creation of the world's first local urban rail network. The Metropolitan Board of Works oversaw infrastructure expansion in the capital and some of the surrounding counties; it was abolished in 1889 when the London County Council was created out of those areas of the counties surrounding the capital. London was bombed by the Germans during the First World War while during the Second World War, the Blitz and other bombings by the German Luftwaffe, killed over 30,000 Londoners and destroyed large tracts of housing and other buildings across the city. Immediately after the war, the 1948 Summer Olympics were held at the original Wembley Stadium, at a time when London had barely recovered from the war.
What was the primary cause of the cholera outbreak in 19th century London?
A:
London's overcrowded conditions
