Input: Friedrich Hayek
On his mother's side, Hayek was second cousin to the philosopher Ludwig Wittgenstein. His mother often played with Wittgenstein's sisters, and had known Ludwig well. As a result of their family relationship, Hayek became one of the first to read Wittgenstein's Tractatus Logico-Philosophicus when the book was published in its original German edition in 1921. Although Hayek met Wittgenstein on only a few occasions, Hayek said that Wittgenstein's philosophy and methods of analysis had a profound influence on his own life and thought. In his later years, Hayek recalled a discussion of philosophy with Wittgenstein, when both were officers during World War I. After Wittgenstein's death, Hayek had intended to write a biography of Wittgenstein and worked on collecting family materials; and he later assisted biographers of Wittgenstein.

Whose philosophy heavily influenced Hayek?
Output: Ludwig Wittgenstein

Input: 2008 Sichuan earthquake
According to a study by the China Earthquake Administration (CEA), the earthquake occurred along the Longmenshan fault, a thrust structure along the border of the Indo-Australian Plate and Eurasian Plate. Seismic activities concentrated on its mid-fracture (known as Yingxiu-Beichuan fracture). The rupture lasted close to 120 sec, with the majority of energy released in the first 80 sec. Starting from Wenchuan, the rupture propagated at an average speed of 3.1 kilometers per second 49 toward north east, rupturing a total of about 300 km. Maximum displacement amounted to 9 meters. The focus was deeper than 10 km.

On which fracture did the quake focus?
Output: Yingxiu-Beichuan fracture

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.

Who is the Brazilian Prime Minister for racial equality?
Output: Elio Ferreira de Araujo

Input: Queen (band)
In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feedback. Sonic experimentation figured heavily in Queen's songs. A distinctive characteristic of Queen's music are the vocal harmonies which are usually composed of the voices of May, Mercury, and Taylor best heard on the studio albums A Night at the Opera and A Day at the Races. Some of the ground work for the development of this sound can be attributed to their former producer Roy Thomas Baker, and their engineer Mike Stone. Besides vocal harmonies, Queen were also known for multi-tracking voices to imitate the sound of a large choir through overdubs. For instance, according to Brian May, there are over 180 vocal overdubs in "Bohemian Rhapsody". The band's vocal structures have been compared with the Beach Boys, but May stated they were not "much of an influence".

What was the name of Brian May's signature guitar?
Output:
Red Special
