Philadelphia artists have had a prominent national role in popular music. In the 1970s, Philadelphia soul influenced the music of that and later eras. On July 13, 1985, Philadelphia hosted the American end of the Live Aid concert at John F. Kennedy Stadium. The city reprised this role for the Live 8 concert, bringing some 700,000 people to the Ben Franklin Parkway on July 2, 2005. Philadelphia is home to the world-renowned Philadelphia Boys Choir & Chorale, which has performed its music all over the world. Dr. Robert G. Hamilton, founder of the choir, is a notable native Philadelphian. The Philly Pops is another famous Philadelphia music group. The city has played a major role in the development and support of American rock music and rap music. Hip-hop/Rap artists such as The Roots, DJ Jazzy Jeff & The Fresh Prince, The Goats, Freeway, Schoolly D, Eve, and Lisa "Left Eye" Lopes hail from the city.

The offices of elder and ministerial servant were restored to Witness congregations in 1972, with appointments made from headquarters (and later, also by branch committees). It was announced that, starting in September 2014, appointments would be made by traveling overseers. In a major organizational overhaul in 1976, the power of the Watch Tower Society president was diminished, with authority for doctrinal and organizational decisions passed to the Governing Body. Since Knorr's death in 1977, the position of president has been occupied by Frederick Franz (1977–1992) and Milton Henschel (1992–2000), both members of the Governing Body, and since 2000 by Don A. Adams, not a member of the Governing Body. In 1995, Jehovah's Witnesses abandoned the idea that Armageddon must occur during the lives of the generation that was alive in 1914 and in 2013 changed their teaching on the "generation".

While technically referring to the era before Christopher Columbus' voyages of 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until Europeans either conquered or significantly influenced them, even if this happened decades or even centuries after Columbus' initial landing. "Pre-Columbian" is used especially often in the context of discussing the great indigenous civilizations of the Americas, such as those of Mesoamerica (the Olmec, the Toltec, the Teotihuacano, the Zapotec, the Mixtec, the Aztec, and the Maya civilizations) and those of the Andes (Inca Empire, Moche culture, Muisca Confederation, Cañaris).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What area of the Americas did the Inca Empire, Moche culture and Muisca confederation hail from?
Ah, so..
Andes
