Input: Consider Input: Question: Which of the Beatles who used the Gibson J-160E were older when they died? Passage:Both John Lennon and George Harrison used the Gibson J-160E, an acoustic guitar with an electric pickup at the base of the fretboard. The resonant character of the full acoustic body, combined with the electric pickup, meant that this guitar was susceptible to feedback, employed to great effect on the intro to "I Feel Fine". Lennon also used a Framus Hootenanny twelve-string acoustic, which can be seen in the movie Help! and heard on the title song and "You've Got to Hide Your Love Away". This twelve-string guitar accounted for audibly richer rhythm guitar parts on songs like these, in comparison to the six-string Gibsons. After Sgt. Pepper's Lonely Hearts Club Band, Lennon moved on to a Martin D-28 from C. F. Martin & Company (alternating between the J-160E and the D-28 for The White Album) while Harrison upgraded to a Gibson J-200 Jumbo (which Lennon used on "Two of Us" and other acoustic tracks on Let It Be).

Passage:He was educated in the German Gymnasium, where he learned the classical languages, and trained as an Indo-Europeanist and a historical and comparative linguist in universities in Munich, Zurich, Padua, and Florence. His refugee status compelled these moves (his grandparents were Jewish, and by 1933 Jews were forbidden to attend German universities). In 1939 he escaped to the United States, where he was at first a research assistant at Yale. He taught at the University of Pennsylvania from 1948 until his retirement in 1985. He was a member of the Linguistic Society of America, of which he was elected President in 1958, and a member of the American Philosophical Society for more than 30 years. He was elected to the National Academy of Sciences. He spent a year at Oxford in 1976 and was elected a Corresponding Fellow of the British Academy in 1986.

Input: Consider Input: Question: Of the foreign countries where James served with his squadron, which one has more land area? Passage:James Hampton was born in 1909 in Elloree, South Carolina as one of four children to James Sr. and Sarah (Johnson) Hampton. His father, who had abandoned the family, was a gospel singer and a traveling Baptist preacher but also a known criminal who had worked on chain gangs. In 1928, Hampton moved to Washington, D.C. and shared an apartment with his older brother Lee. Hampton worked as a short-order cook until 1943 when he was drafted into the United States Army Air Forces. He served with the 385th Aviation Squadron in Texas, Hawaii, and in the jungles of Saipan and Guam. The segregated unit was noncombatant and duties included carpentry and maintenance of airstrips. Hampton built a small shrine-like object during his time in Guam which he incorporated into his larger artwork later. He was awarded the Bronze Star, honorably discharged in 1945 and returned to Washington, D.C. In 1946, Hampton was hired by the General Services Administration as a janitor and worked there until his death.
