[EX Q]: 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?
[EX A]: 351st Bombardment Group.

[EX Q]: Passage: In 1986, Gilmour began recruiting musicians for what would become Pink Floyd's first album without Waters, A Momentary Lapse of Reason. There were legal obstacles to Wright's re-admittance to the band, but after a meeting in Hampstead, Pink Floyd invited Wright to participate in the coming sessions. Gilmour later stated that Wright's presence "would make us stronger legally and musically", and Pink Floyd employed him as a musician with weekly earnings of $11,000. Recording sessions began on Gilmour's houseboat, the Astoria, moored along the River Thames. Gilmour worked with several songwriters, including Eric Stewart and Roger McGough, eventually choosing Anthony Moore to write the album's lyrics. Gilmour would later admit that the project was difficult without Waters' creative direction. Mason, concerned that he was too out-of-practice to perform on the album, made use of session musicians to complete many of the drum parts. He instead busied himself with the album's sound effects.A Momentary Lapse of Reason was released in September 1987. Storm Thorgerson, whose creative input was absent from The Wall and The Final Cut, designed the album cover. To drive home that Waters had left the band, they included a group photograph on the inside cover, the first since Meddle. The album went straight to number three in the UK and the US. Waters commented: "I think it's facile, but a quite clever forgery ... The songs are poor in general ... [and] Gilmour's lyrics are third-rate." Although Gilmour initially viewed the album as a return to the band's top form, Wright disagreed, stating: "Roger's criticisms are fair. It's not a band album at all." Q Magazine described the album as essentially a Gilmour solo album.Waters attempted to subvert the Momentary Lapse of Reason tour by contacting promoters in the US and threatening to sue them if they used the Pink Floyd name. Gilmour and Mason funded the start-up costs with Mason using his Ferrari 250 GTO as collateral. Early rehearsals for the upcoming tour were chaotic, with Mason and Wright entirely out of practice. Realising he had taken on too much work, Gilmour asked Ezrin to assist them. As Pink Floyd toured North America, Waters' Radio K.A.O.S. tour was on occasion, close by, though in much smaller venues than those hosting his former band's performances. Waters issued a writ for copyright fees for the band's use of the flying pig. Pink Floyd responded by attaching a large set of male genitalia to its underside to distinguish it from Waters' design. The parties reached a legal agreement on 23 December; Mason and Gilmour retained the right to use the Pink Floyd name in perpetuity and Waters received exclusive rights to, among other things, The Wall. 
Question: What did the person who designed the flying pig get rights to in the 23 December legal agreement?
[EX A]: The Wall.

[EX Q]: Passage: In 1983, theater and opera director Peter Sellars proposed to American composer John Adams that he write an opera about Nixon's 1972 visit to China. Sellars was intrigued by Nixon's decision to make the visit, seeing it as both "a ridiculously cynical election ploy ... and a historical breakthrough". Adams, who had not previously attempted an opera, was initially skeptical, assuming that Sellars was proposing a satire. Sellars persisted, however, and Adams, who had interested himself in the origin of myths, came to believe the opera could show how mythic origins may be found in contemporary history.  Both men agreed that the opera would be heroic in nature, rather than poking fun at Nixon or Mao.  Sellars invited Alice Goodman to join the project as librettist,  and the three met at the Kennedy Center in Washington D.C. in 1985 to begin intensive study of the six characters, three American and three Chinese, upon whom the opera would focus. The trio endeavored to go beyond the stereotypes about figures such as Nixon and Chinese Chairman Mao Tse-tung and to examine their personalities.As Adams worked on the opera, he came to see Nixon, whom he had once intensely disliked, as an "interesting character", a complicated individual who sometimes showed emotion in public.  Adams wanted Mao to be "the Mao of the huge posters and Great Leap Forward; I cast him as a heldentenor".  Mao's wife, on the other hand, was to be "not just a shrieking coloratura, but also someone who in the opera's final act can reveal her private fantasies, her erotic desires, and even a certain tragic awareness.  Nixon himself is a sort of Simon Boccanegra, a self-doubting, lyrical, at times self-pitying melancholy baritone."Goodman explained her characterizations:
A writer tends to find her characters in her self, so I can tell you ... that Nixon, Pat, Mme. Mao, Kissinger and the chorus were all 'me.' And the inner lives of Mao and Chou En-Lai, who I couldn't find in myself at all, were drawn from a couple of close acquaintances. 
Question: What are the full names of the two men would agreed that the opera would be heroic in nature?
[EX A]:
Peter Sellars.
