[EX Q]: 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 160608. 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 162425, 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 163940 carnival season, a revival of his L'Arianna at the Teatro San Moise.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 164041 carnival; Monteverdi's music is lost, but a copy of the libretto, of unknown authorship, survives. The last of the three, written for the 164243 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?
[EX A]: Teatro San Moise.

[EX Q]: Passage: "Halo" was composed by Ryan Tedder, lead vocalist of OneRepublic, together with Evan "Kidd" Bogart and Beyonce. In an interview for HitQuarters, Kidd narrated the events that led to writing the song. OneRepublic canceled their tour after Tedder had broken his Achilles tendon and had undergone surgery. The following day, the band sent Tedder to Los Angeles. There, he and Kidd were socializing when Tedder expressed his desire to write a song. Kidd was initially opposed to the idea because Tedder was supposed to be recuperating, but the pair went to Tedder's studio. During the writing sessions, singer Ray LaMontagne was the primary inspiration for "Halo". Kidd suggested they create a song in the style of LaMontagne's "Shelter" for Beyonce and her husband Jay-Z, and proposed the title "Halo" after hearing Tedder play "angelic" chords. They wrote the song in three hours.According to Simon Cowell, owner of the music production company Syco Entertainment, Bogart and Tedder intended "Halo" for his client, singer Leona Lewis, who could not record the song because of her tight schedule. Cowell was upset that Beyonce chose to record the song. David Balls, editor of the British media website Digital Spy, asked Tedder during an interview whether "Halo" had initially been written for Lewis. Tedder answered that he had only tentatively offered the track to Lewis, after Beyonce waited a long time before recording it. He commented:
There was this huge scandal that originally "Halo" was meant to go to Leona. That was never the case ... That song was written for Beyonce. What happened was that Beyonce waited long enough to record that song ... I thought this would be a brilliant first single for Leona, which it would have ... What I did was foolishly say to Leona's camp, "I have it on hold for another A-list artist and I'm pretty sure they'll take it, but if they don't, I just want to know if you like it enough to consider it". I sent it to them and they flipped on it. They loved it and instantly said they wanted to do it. I was like, "Wait, wait, wait, no, it's not free yet!".
Question: What is the first name of the person who broke his Achilles tendon?
[EX A]: Ryan.

[EX Q]: Passage: Frank Chambers a drifter, stops at a depression-era rural California diner for a meal and ends up working there. The diner is operated by a young, beautiful woman, Cora Smith, and her much older husband, Nick Papadakis, a hardworking but unimaginative immigrant from Greece.
Frank and Cora start to have an affair soon after they meet. Cora is tired of her situation, married to an older man she does not love, and working at a diner that she wishes to own and improve. She and Frank scheme to murder Nick to start a new life together without her losing the diner. Their first attempt at the murder is a failure, but Nick is not even aware they tried to kill him, so goes about living his life as usual. Frank and Cora succeed with their next attempt.
The local prosecutor suspects what has actually occurred but does not have enough evidence to prove it. As a tactic intended to get Cora and Frank to turn on one another, he tries only Cora for the crime.
Although they turn against each other, a clever ploy from Cora's lawyer, Katz, prevents Cora's full confession from coming into the hands of the prosecutor. With the tactic having failed to generate any new evidence for the prosecution, Cora benefits from a deal in which she pleads guilty to manslaughter and is sentenced to probation.
Months later, Frank has an affair with Madge Gorland while Cora is out of town. When Cora returns, she tells Frank she is pregnant. That night, Katz's assistant, Kennedy, appears at their door and threatens to expose them unless they give him $10,000. Enraged, Frank beats Kennedy up and strong-arms him into giving up the evidence against them.
Question: What is the last name of the person who is hired by Cora and Nick?
[EX A]:
Chambers.
