Input: Post-punk
Generally, post-punk music is defined as music that emerged from the cultural milieu of punk rock in the late 1970s, although many groups now categorized as post-punk were initially subsumed under the broad umbrella of punk or new wave music, only becoming differentiated as the terms came to signify more narrow styles. Additionally, the accuracy of the term's chronological prefix "post" has been disputed, as various groups commonly labeled post-punk in fact predate the punk rock movement. Reynolds defined the post-punk era as occurring loosely between 1978 and 1984.

What previous movement is post-punk often identified as coming after?
Output: punk rock

Input: Indigenous peoples of the Americas
Cultural practices in the Americas seem to have been shared mostly within geographical zones where unrelated peoples adopted similar technologies and social organizations. An example of such a cultural area is Mesoamerica, where millennia of coexistence and shared development among the peoples of the region produced a fairly homogeneous culture with complex agricultural and social patterns. Another well-known example is the North American plains where until the 19th century several peoples shared the traits of nomadic hunter-gatherers based primarily on buffalo hunting.

What creature did the nomadic hunter-gatherers of the plains hunt?
Output: buffalo

Input: The Blitz
The relieved British began to assess the impact of the Blitz in August 1941, and the RAF Air Staff used the German experience to improve Bomber Command's offensives. They concluded bombers should strike a single target each night and use more incendiaries because they had a greater impact on production than high explosives. They also noted regional production was severely disrupted when city centres were devastated through the loss of administrative offices, utilities and transport. They believed the Luftwaffe had failed in precision attack, and concluded the German example of area attack using incendiaries was the way forward for operations over Germany.

What caused the most production disruption?
Output: when city centres were devastated through the loss of administrative offices, utilities and transport.

Input: Black people
Because of the acceptance of miscegenation, Brazil has avoided the binary polarization of society into black and white. In addition, it abolished slavery without a civil war. The bitter and sometimes violent racial tensions that have divided the US are notably absent in Brazil. According to the 2010 census, 6.7% of Brazilians said they were black, compared with 6.2% in 2000, and 43.1% said they were racially mixed, up from 38.5%. In 2010, Elio Ferreira de Araujo, Brazil's minister for racial equality, attributed the increases to growing pride among his country's black and indigenous communities.

What is happened in the US that did not happen in Brazil when slavery ended?
Output:
civil war
