Input: Queen (band)
Before forming Queen, Brian May and Roger Taylor had played together in a band named Smile. Freddie Mercury (then known by his birth name of Farrokh "Freddie" Bulsara) was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. Mercury joined the band in 1970, suggested "Queen" as a new band name, and adopted his familiar stage name. John Deacon was recruited prior to recording their eponymous debut album in 1973. Queen first charted in the UK with their second album, Queen II, in 1974, but it was the release of Sheer Heart Attack later that year and A Night at the Opera in 1975 which brought them international success. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK for nine weeks and popularised the music video. Their 1977 album, News of the World, contained "We Will Rock You" and "We Are the Champions", which have become anthems at sporting events. By the early 1980s, Queen were one of the biggest stadium rock bands in the world. Their performance at 1985's Live Aid is ranked among the greatest in rock history by various music publications, with a 2005 industry poll ranking it the best. In 1991, Mercury died of bronchopneumonia, a complication of AIDS, and Deacon retired in 1997. Since then, May and Taylor have occasionally performed together, including with Paul Rodgers (200409) and with Adam Lambert (since 2011). In November 2014, Queen released a new album, Queen Forever, featuring vocals from the late Mercury.

What was the name of Brian May and Roger Taylor's band before Queen?

Input: Indigenous peoples of the Americas
Indigenous peoples of Brazil make up 0.4% of Brazil's population, or about 700,000 people, even though millions of Brazilians have some indigenous ancestry. Indigenous peoples are found in the entire territory of Brazil, although the majority of them live in Indian reservations in the North and Center-Western part of the country. On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted tribes.

How much of Brazil's population is comprised of indigenous peoples?
Output: 0.4%

Input: 2008 Sichuan earthquake
The Zipingpu Hydropower Plant (simplified Chinese: ; traditional Chinese: ) located 20 km east of the epicenter was damaged. A recent inspection indicated that the damage was less severe than initially feared, and it remains structurally stable and safe. The Tulong reservoir upstream is in danger of collapse. About 2,000 troops have been allocated to Zipingpu, trying to release the pressure through spillway. In total, 391 dams, most of them small, were reported damaged by the quake.

What might possibly collapse upstream from the power plant?
Output: Tulong reservoir

Input: The Blitz
Ultimately, Hitler was trapped within his own vision of bombing as a terror weapon, formed in the 1930s when he threatened smaller nations into accepting German rule rather than submit to air bombardment. This fact had important implications. It showed the extent to which Hitler personally mistook Allied strategy for one of morale breaking instead of one of economic warfare, with the collapse of morale as an additional bonus. Hitler was much more attracted to the political aspects of bombing. As the mere threat of it had produced diplomatic results in the 1930s, he expected that the threat of German retaliation would persuade the Allies to adopt a policy of moderation and not to begin a policy of unrestricted bombing. His hope was for reasons of political prestige within Germany itself that the German population would be protected from the Allied bombings. When this proved impossible, he began to fear that popular feeling would turn against his regime, and he redoubled efforts to mount a similar "terror offensive" against Britain in order to produce a stalemate in which both sides would hesitate to use bombing at all.

Why did Hitler use terror bombing against Britain?
Output:
to produce a stalemate
