Question: Passage: In 1943, in preparation for overseas deployment, 400 pilots and 3,600 crewmen of the 351st Bombardment Group assemble at a Colorado air base. Arriving in England, as part of the Eighth Air Force, the 351st BG is welcomed by the Royal Air Force and begins training, attending daily lectures on security. Their first mission flying Boeing B-17 Flying Fortress bombers has the armada departing at 15-second intervals.
The first mission of the 351st on Fortress Europe, after fighting through Luftwaffe defenders, is a success, with all 20 B-17s returning safely back to base. The danger of flying in massed formation, however, is brought home in training, when a collision takes place over the home base. Missions are also not always without casualties and 351st bombers are shot down. Wounded airmen who make it back to base, are cared for at a nearby hospital. When bombers are all shot up, the ground crew works up to 90-hour periods to put them back into service.
As the mission tallies build, the men partake in activities at the base, including games, socializing and worship. The U.S.O. brings entertainers such as Bob Hope while the Red Cross provides the men with rest and recreation. During special parades, commanders of the 8th Air Force bestow medals for exceptional service and sacrifice.
The 351st participates in a big mission into Germany and after flying for about three hours, the B-17s' fighter escort turns back. As the bombers near their target to drop incendiary and anti-personnel bombs, enemy fighter aircraft appear and intense flak comes up from the ground. After a long battle, the 351st returns to base, ready to fight again until the war is over.
Question: What is the formal name for the armada?

Answer: 351st Bombardment Group.

Question: Passage: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Muhlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbuchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskonig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Kothen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Kothen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend wei, BWV 134.
Question: What is the last name of the person who parodied some secular cantatas as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend wei, BWV 134?

Answer: Bach.

Question: Passage: The underground punk rock movement inspired countless bands that either evolved from a punk rock sound or brought its outsider spirit to very different kinds of music. The original punk explosion also had a long-term effect on the music industry, spurring the growth of the independent sector. During the early 1980s, British bands like New Order and the Cure that straddled the lines of post-punk and new wave developed both new musical styles and a distinctive industrial niche. Though commercially successful over an extended period, they maintained an underground-style, subcultural identity. In the United States, bands such as Husker Du and their Minneapolis proteges the Replacements bridged the gap between punk rock genres like hardcore and the more melodic, explorative realm of what was then called "college rock".A 1985 Rolling Stone feature on the Minneapolis scene and innovative California hardcore acts such as Black Flag and Minutemen declared, "Primal punk is passe. The best of the American punk rockers have moved on. They have learned how to play their instruments. They have discovered melody, guitar solos and lyrics that are more than shouted political slogans. Some of them have even discovered the Grateful Dead." By the mid-to-late 1980s, these bands, who had largely eclipsed their punk rock and post-punk forebears in popularity, were classified broadly as alternative rock. Alternative rock encompasses a diverse set of stylesincluding indie rock, gothic rock, dream pop, shoegaze, and grunge, among othersunified by their debt to punk rock and their origins outside of the musical mainstream.As American alternative bands like Sonic Youth, which had grown out of the no wave scene, and Boston's Pixies started to gain larger audiences, major labels sought to capitalize on the underground market that had been sustained by hardcore punk for years. In 1991, Nirvana emerged from Washington State's underground, DIY grunge scene; after recording their first album, Bleach for about $600, the band achieved huge (and unexpected) commercial success with its second album, Nevermind. The band's members cited punk rock as a key influence on their style. "Punk is musical freedom", wrote frontman Kurt Cobain. "It's saying, doing, and playing what you want." Nirvana's success opened the door to mainstream popularity for a wide range of other "left-of-the-dial" acts, such as Pearl Jam and Red Hot Chili Peppers, and fueled the alternative rock boom of the early and mid-1990s.
Question: What two punk rock genres did the Replacements and Husker Du build the gap between?

Answer:
hardcore.
