Example Input: Question: What song on Hammer's debut album samples a song by the same name from BB King? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.

Example Input: Question: Who is older, Lisker or the phonetician that he principally worked with? Passage:Leigh Lisker (December 7, 1918 – March 24, 2006) was an eminent American linguist and phonetician. Most of his career was spent at the University of Pennsylvania, where he was a professor and then emeritus professor of linguistics. Dr. Lisker received his A.B. in 1941, with a major in German, his M.A. in 1946, and a Ph.D. in 1949 in linguistics. He was a major figure in phonetics, working both at the University of Pennsylvania and at Haskins Laboratories in New Haven, CT, where he was a senior scientist from 1951 until the end of his life. He collaborated with several phoneticians, principally Arthur S. Abramson. He is best known for his work, done mostly in conjunction with Abramson, on voice onset time. Dr. Lisker also made important contributions to Dravidian linguistics, including the book Introduction to Spoken Telugu (Telugu), and did research comparing phonetic and phonological perceptions on the part of linguistically naive and linguistically sophisticated speakers of different native language backgrounds. He conducted such studies in collaboration with Dr. Abramson of the University of Connecticut, Bh. Krishnamurti  of University of Hyderabad, India, Adrian Fourcin  of University College London, and Mario Rossi  of the Institut de Phonétique at the Université de Provence, Aix-en-Provence.
