Input: Read this: There are two major mechanical pulps, the thermomechanical one (TMP) and groundwood pulp (GW). In the TMP process, wood is chipped and then fed into large steam heated refiners, where the chips are squeezed and converted to fibres between two steel discs. In the groundwood process, debarked logs are fed into grinders where they are pressed against rotating stones to be made into fibres. Mechanical pulping does not remove the lignin, so the yield is very high, >95%, however it causes the paper thus produced to turn yellow and become brittle over time. Mechanical pulps have rather short fibres, thus producing weak paper. Although large amounts of electrical energy are required to produce mechanical pulp, it costs less than the chemical kind.
Question: What is not the main ingredient in the groundwood process?

Output: unanswerable

Input: Read this: Blues rock acts that pioneered the sound included Cream, The Jimi Hendrix Experience, and The Jeff Beck Group. Cream, in songs like "I Feel Free" (1966) combined blues rock with pop and psychedelia, particularly in the riffs and guitar solos of Eric Clapton. Jimi Hendrix produced a form of blues-influenced psychedelic rock, which combined elements of jazz, blues and rock and roll. From 1967 Jeff Beck brought lead guitar to new heights of technical virtuosity and moved blues rock in the direction of heavy rock with his band, The Jeff Beck Group. Dave Davies of The Kinks, Keith Richards of The Rolling Stones, Pete Townshend of The Who, Hendrix, Clapton and Beck all pioneered the use of new guitar effects like phasing, feedback and distortion. The Beatles began producing songs in the new hard rock style beginning with the White Album in 1968 and, with the track "Helter Skelter", attempted to create a greater level of noise than the Who. Stephen Thomas Erlewine of AllMusic has described the "proto-metal roar" of "Helter Skelter," while Ian MacDonald argued that "their attempts at emulating the heavy style were without exception embarrassing."
Question: Who was the guitarist in the Kinks?

Output: Dave Davies

Input: Read this: Unfortunately, Isabella was already engaged to Hugh of Lusignan, an important member of a key Poitou noble family and brother of Count Raoul of Eu, who possessed lands along the sensitive eastern Normandy border. Just as John stood to benefit strategically from marrying Isabella, so the marriage threatened the interests of the Lusignans, whose own lands currently provided the key route for royal goods and troops across Aquitaine. Rather than negotiating some form of compensation, John treated Hugh "with contempt"; this resulted in a Lusignan uprising that was promptly crushed by John, who also intervened to suppress Raoul in Normandy.
Question: Hugh of Lusignan was an important member of what?

Output: a key Poitou noble family

Input: Read this: In the 200506 season, Barcelona repeated their league and Supercup successes. The pinnacle of the league season arrived at the Santiago Bernabeu Stadium in a 30 win over Real Madrid. It was Frank Rijkaard's second victory at the Bernabeu, making him the first Barcelona manager to win there twice. Ronaldinho's performance was so impressive that after his second goal, which was Barcelona's third, some Real Madrid fans gave him a standing ovation. In the Champions League, Barcelona beat the English club Arsenal in the final. Trailing 10 to a 10-man Arsenal and with less than 15 minutes remaining, they came back to win 21, with substitute Henrik Larsson, in his final appearance for the club, setting up goals for Samuel Eto'o and fellow substitute Juliano Belletti, for the club's first European Cup victory in 14 years.
Question: What team did Barcelona defeat to win the Champions League trophy?
