Background: The Who are an English rock band that formed in 1964. Their classic line-up consisted of lead singer Roger Daltrey, guitarist and singer Pete Townshend, bass guitarist John Entwistle, and drummer Keith Moon. They are considered one of the most influential rock bands of the 20th century, selling over 100 million records worldwide and holding a reputation for their live shows and studio work. The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by destroying guitars and drums on stage.
Context: The founding members of the Who, Roger Daltrey, Pete Townshend and John Entwistle, grew up in Acton, London and went to Acton County Grammar School. Townshend's father, Cliff, played saxophone and his mother, Betty, had sung in the entertainment division of the Royal Air Force during World War II, and both supported their son's interest in rock and roll. Townshend and Entwistle became friends in their second year of Acton County, and formed a trad jazz group; Entwistle also played French horn in the Middlesex Schools' Symphony Orchestra. Both were interested in rock, and Townshend particularly admired Cliff Richard's debut single, "Move It". Entwistle moved to guitar, but struggled with it due to his large fingers, and moved to bass on hearing the guitar work of Duane Eddy. He was unable to afford a bass and built one at home. After Acton County, Townshend attended Ealing Art College, a move he later described as profoundly influential on the course of the Who.  Daltrey, who was in the year above, had moved to Acton from Shepherd's Bush, a more working-class area. He had trouble fitting in at the school, and discovered gangs and rock and roll. He was expelled at 15 and found work on a building site. In 1959 he started the Detours, the band that was to evolve into the Who. The band played professional gigs, such as corporate and wedding functions, and Daltrey kept a close eye on the finances as well as the music.  Daltrey spotted Entwistle by chance on the street carrying a bass and recruited him into the Detours. In mid-1961, Entwistle suggested Townshend as a guitarist, Daltrey on lead guitar, Entwistle on bass, Harry Wilson on drums, and Colin Dawson on vocals. The band played instrumentals by the Shadows and the Ventures, and a variety of pop and trad jazz covers. Daltrey was considered the leader and, according to Townshend, "ran things the way he wanted them". Wilson was fired in mid-1962 and replaced by Doug Sandom, though he was older than the rest of the band, married, and a more proficient musician, having been playing semi-professionally for two years.  Dawson left after frequently arguing with Daltrey and after being briefly replaced by Gabby Connolly, Daltrey moved to lead vocals. Townshend, with Entwistle's encouragement, became the sole guitarist. Through Townshend's mother, the group obtained a management contract with local promoter Robert Druce, who started booking the band as a support act. The Detours were influenced by the bands they supported, including Screaming Lord Sutch, Cliff Bennett and the Rebel Rousers, Shane Fenton and the Fentones, and Johnny Kidd and the Pirates. The Detours were particularly interested in the Pirates as they also only had one guitarist, Mick Green, who inspired Townshend to combine rhythm and lead guitar in his style. Entwistle's bass became more of a lead instrument, playing melodies. In February 1964, the Detours became aware of the group Johnny Devlin and the Detours and changed their name. Townshend and his roommate Richard Barnes spent a night considering names, focusing on a theme of joke announcements, including "No One" and "the Group". Townshend preferred "the Hair", and Barnes liked "the Who" because it "had a pop punch". Daltrey chose "the Who" the next morning.
Question: what did they change their name to?
Answer: Daltrey chose "the Who" the next morning.

Problem: Background: Menachem Begin ( listen ; Hebrew: m@nakhem be'giyn Menahem Begin, Polish: Mieczyslaw Biegun; Russian: Menakhem Vol'fovich Begin Menakhem Volfovich Begin; 16 August 1913 - 9 March 1992) was an Israeli politician, founder of Likud and the sixth Prime Minister of Israel.
Context: In 1978 Begin, aided by Foreign Minister Moshe Dayan and Defense Minister Ezer Weizman, came to Washington and Camp David to negotiate the Camp David Accords, leading to the 1979 Egypt-Israel Peace Treaty with Egyptian President, Anwar Sadat. Before going to Washington to meet President Carter, Begin visited Rabbi Menachem M. Schneerson for his advice. Under the terms of the treaty, brokered by US President, Jimmy Carter, Israel was to hand over the Sinai Peninsula in its entirety to Egypt. The peace treaty with Egypt was a watershed moment in Middle Eastern history, as it was the first time an Arab state recognized Israel's legitimacy whereas Israel effectively accepted the land for peace principle as blueprint for resolving the Arab-Israeli conflict. Given Egypt's prominent position within the Arab World, especially as Israel's biggest and most powerful enemy, the treaty had far reaching strategic and geopolitical implications.  Almost overnight, Begin's public image of an irresponsible nationalist radical was transformed into that of a statesman of historic proportions. This image was reinforced by international recognition which culminated with him being awarded, together with Sadat, the Nobel Peace Prize in 1978.  Yet while establishing Begin as a leader with broad public appeal, the peace treaty with Egypt was met with fierce criticism within his own Likud party. His devout followers found it difficult to reconcile Begin's history as a keen promoter of the Greater Israel agenda with his willingness to relinquish occupied territory. Agreeing to the removal of Israeli settlements from the Sinai was perceived by many as a clear departure from Likud's Revisionist ideology. Several prominent Likud members, most notably Yitzhak Shamir, objected to the treaty and abstained when it was ratified with an overwhelming majority in the Knesset, achieved only thanks to support from the opposition. A small group of hardliners within Likud, associated with Gush Emunim Jewish settlement movement, eventually decided to split and form the Tehiya party in 1979. They led the Movement for Stopping the Withdrawal from Sinai, violently clashing with IDF soldiers during the forceful eviction of Yamit settlement in April 1982. Despite the traumatic scenes from Yamit, political support for the treaty did not diminish and the Sinai was handed over to Egypt in 1982.  Begin was less resolute in implementing the section of the Camp David Accord calling for Palestinian self-rule in the West Bank and Gaza Strip. He appointed Agriculture Minister Ariel Sharon to implement a large scale expansion of Jewish settlements in the Israeli-occupied territories, a policy intended to make future territorial concessions in these areas effectively impossible. Begin refocused Israeli settlement strategy from populating peripheral areas in accordance with the Allon Plan, to building Jewish settlements in areas of Biblical and historic significance. When the settlement of Elon Moreh was established on the outskirts of Nablus in 1979, following years of campaigning by Gush Emunim, Begin declared that there are "many more Elon Morehs to come." During his term dozens of new settlements were built, and Jewish population in the West Bank and Gaza more than quadrupled.
