[EX Q]: Question: Which opera that Brambilla performed at Teatro Carcano was written first? Passage:After her professional debut in 1831, Brambilla initially sang in several smaller opera houses in northern Italy but in 1833 scored a considerable success at Milan's Teatro Carcano singing Agnese in Bellini's Beatrice di Tenda and the leading soprano role in Fioravanti's Le cantatrici villane. She then appeared on Russia at the Odessa Opera House, which at the time specialised in Italian opera. Upon her return to Milan in 1837, she sang with her sister Marietta at La Scala in the world premiere of In morte di Maria Malibran de Beriot, a cantata in memory of Maria Malibran composed by Gaetano Donizetti, Giovanni Pacini, Saverio Mercadante, Nicola Vaccai and Pietro Antonio Coppola. After singing in Barcelona, she returned to La Scala for the 1839/1840 season in Mercadante's Le due illustri rivali and the world premieres of Mazzucato's I corsari and Coccia's Giovanna II.

[EX Q]: Question: Which Philadelphia sport team with a fantasy creature mascot was found first? Passage:In the world of sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are often used as marketing tools for their teams to children. Since the mid-20th century, costumed characters have provided teams with an opportunity to choose a fantasy creature as their mascot, as is the case with the Philadelphia Phillies' mascot, the Phillie Phanatic, and the Philadelphia Flyers' mascot, Gritty.

[EX Q]: Question: How long is that river that Cornwallis crossed to reach New Jersey? Passage:While 1776 had started well for the American cause with the evacuation of British troops from Boston in March, the defense of New York City had gone quite poorly. British general William Howe had landed troops on Long Island in August and had pushed George Washington's Continental Army completely out of New York by mid-November, when he captured the remaining troops on Manhattan. The main British troops returned to New York for the winter season. They left mainly Hessian troops in New Jersey. These troops were under the command of Colonel Rall and Colonel Von Donop. They were ordered to small outposts in and around Trenton. Howe then sent troops under the command of Charles Cornwallis across the Hudson River into New Jersey and chased Washington across New Jersey. Washington's army was shrinking, due to expiring enlistments and desertions, and suffered from poor morale, due to the defeats in the New York area. Most of Washington's army crossed the Delaware River into Pennsylvania north of Trenton, New Jersey, and destroyed or moved to the western shore all boats for miles in both directions. Cornwallis (under Howe's command), rather than attempting to immediately chase Washington further, established a chain of outposts from New Brunswick to Burlington, including one at Bordentown and one at Trenton, and ordered his troops into winter quarters. The British were happy to end the campaign season when they were ordered to winter quarters. This was a time for the generals to regroup, re-supply, and strategize for the upcoming campaign season the following spring.
