Passage: 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."

Ex Output:
Who was a hard rock act that pioneered the blues sound?

Passage: Harvard's academic programs operate on a semester calendar beginning in early September and ending in mid-May. Undergraduates typically take four half-courses per term and must maintain a four-course rate average to be considered full-time. In many concentrations, students can elect to pursue a basic program or an honors-eligible program requiring a senior thesis and/or advanced course work. Students graduating in the top 45% of the class are awarded degrees summa cum laude, students in the next 15% of the class are awarded magna cum laude, and the next 30% of the class are awarded cum laude. Harvard has chapters of academic honor societies such as Phi Beta Kappa and various committees and departments also award several hundred named prizes annually. Harvard, along with other universities, has been accused of grade inflation, although there is evidence that the quality of the student body and its motivation have also increased. Harvard College reduced the number of students who receive Latin honors from 90% in 2004 to 60% in 2005. Moreover, the honors of "John Harvard Scholar" and "Harvard College Scholar" will now be given only to the top 5 percent and the next 5 percent of each class.

Ex Output:
What does a basic program also require?

Passage: Prior Diego saw immediately one of the paramount reasons for the spread of the unorthodox movement: the representatives of the Holy Church acted and moved with an offensive amount of pomp and ceremony. On the other hand, the Cathars lived in a state of self-sacrifice that was widely appealing. For these reasons, Prior Diego suggested that the papal legates begin to live a reformed apostolic life. The legates agreed to change if they could find a strong leader. The prior took up the challenge, and he and Dominic dedicated themselves to the conversion of the Albigensians. Despite this particular mission, in winning the Albigensians over by persuasion Dominic met limited success, "for though in his ten years of preaching a large number of converts were made, it has to be said that the results were not such as had been hoped for."

Ex Output:
Who did not immediately see one of the paramount reasons for the spread of the unorthodox movement?
