Example Input: Question: Was Pete Townshend younger than Brian May the year "My Generation" was released? Passage:A deliberate use of acoustic feedback was pioneered by Blues and Rock'n'Roll guitarists such as Willie Johnson, Johnny Watson and Link Wray. According to AllMusic's Richie Unterberger, the very first use of feedback on a commercial rock record is the introduction of the song "I Feel Fine" by the Beatles, recorded in 1964. Jay Hodgson agrees that it was the first chart-topper to showcase feedback distortion, created by John Lennon leaning a semi-acoustic guitar against an amplifier. The Who's 1965 hits "Anyway, Anyhow, Anywhere" and "My Generation" featured feedback manipulation by Pete Townshend, with an extended solo in the former and the shaking of his guitar in front of the amplifier to create a throbbing noise in the latter. Canned Heat's "Fried Hockey Boogie" (off of their 1968 album Boogie with Canned Heat) also featured guitar feedback produced by Henry Vestine during his solo to create a highly amplified distorted boogie style of feedback. In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feed back.

Example Input: Question: What party controlled the legislative branch of government the  Dixiecrats hoped to force a contingent election in 1948? Passage:Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.
