question:
Passage: Monteverdi was an established court composer in the service of Duke Vincenzo Gonzaga in Mantua when he wrote his first operas, L'Orfeo and L'Arianna, in the years 1606–08. After falling out with Vincenzo's successor, Duke Francesco Gonzaga, Monteverdi moved to Venice in 1613 and became director of music at St Mark's Basilica, a position he held for the rest of his life. Alongside his steady output of madrigals and church music, Monteverdi continued to compose works for the stage, though not actual operas. He wrote several ballets and, for the Venice carnival of 1624–25, Il combattimento di Tancredi e Clorinda ("The Battle of Tancred and Clorinda"), a hybrid work with some characteristics of ballet, opera and oratorio.
In 1637 fully-fledged opera came to Venice with the opening of the Teatro San Cassiano. Sponsored by the wealthy Tron family, this theatre was the first in the world specifically devoted to opera. The theatre's inaugural performance, on 6 March 1637, was L'Andromeda by Francesco Manelli and Benedetto Ferrari. This work was received with great enthusiasm, as was the same pair's La Maga fulminata the following year. In rapid succession three more opera houses opened in the city, as the ruling families of the Republic sought to express their wealth and status by investing in the new musical fashion. At first, Monteverdi remained aloof from these activities, perhaps on account of his age (he was over 70), or perhaps through the dignity of his office as maestro di capella at St. Mark's. Nevertheless, an unidentified contemporary, commenting on Monteverdi's silence, opined that the maestro might yet produce an opera for Venice: "God willing, one of these nights he too will step onto the stage." This remark proved prescient; Monteverdi's first public contribution to Venetian opera came in the 1639–40 carnival season, a revival of his L'Arianna at the Teatro San Moisè.L'Arianna was followed in rapid succession by three brand new Monteverdi operas, of which Il ritorno was the first. The second, Le nozze d' Enea in Lavinia ("The Marriage of Aeneas to Lavinia"), was performed during the 1640–41 carnival; Monteverdi's music is lost, but a copy of the libretto, of unknown authorship, survives. The last of the three, written for the 1642–43 carnival, was L'incoronazione di Poppea ("The Coronation of Poppea"), performed shortly before the composer's death in 1643. 
Question: Where did Monteverdi perform his first opera?
answer:
Teatro San Moisè.

Hispanic or Latino (of any race): 10.5% (7.0% Mexican, 1.3% Ecuadorian, 0.4% Puerto Rican, 0.3% Guatemalan, 0.2% Salvadoran, 1.3% Other Latino)White Americans make up about three-fifths of Minneapolis's population.

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.
