Problem: Given the question: Read the following paragraph and extract the answer for the question: What is the first name of the person that threatens to give the opening night lead role to Liz? In 2004, Broadway diva Kylie Swanson opened the musical The Haunting of the Opera (a reference to real-life musical The Phantom of the Opera) to a packed audience. However, that same night, she was murdered backstage by an unknown assailant wearing the mask of the play's villain, Opera Ghost. 10 years later in the present-day, Kylie's children Camilla and Buddy have grown up raised by Roger McCall, a former lover of Kylie's and the producer of a musical theater summer camp on the brink of bankruptcy. When Camilla hears that the camp will be producing a kabuki version of The Haunting of the Opera, she decides that she will sneak into auditions one way or another. She manages to convince a camper overseeing the auditions, Joel Hopton, to let her in and Camilla easily impresses the stage director Artie and wins the lead role of Sofia - much to Buddy's dismay. As the opening day grows closer and closer, Camilla discovers that Artie will only let her perform on opening day as long as she provides him with sexual favors. He emotionally blackmails her by playing her off of Liz Silver, a camper that will do anything to perform on opening night. Camilla tries to ward off Artie's attentions by only making out with him, which disgusts Joel - whom Camilla has largely ignored since the audition. The night before the performance, Artie gives Camilla an ultimatum: either she sleeps with him or he gives the opening night performance to Liz. Camilla initially acquiesces to Artie's overtures, but decides at the last minute that she can't go through with it. After she leaves, Artie is brutally murdered by someone wearing the Opera Ghost mask, but Roger tells everyone that Artie died by car accident. Unwilling to potentially lose a visit from important Broadway agent Victor Brady, who is only willing to watch the performance if Camilla is performing, Roger manages to persuade everyone to perform opening night as planned.

Problem: Given the question: Read the following paragraph and extract the answer for the question: What did Carmen show on stage that broke new ground in the genre? Carmen (French pronunciation: [kamn]; Spanish: [kamen]) is an opera in four acts by French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halevy, based on a novella of the same title by Prosper Merimee. The opera was first performed by the Opera-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences. Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years. Carmen has since become one of the most popular and frequently performed operas in the classical canon; the "Habanera" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias. The opera is written in the genre of opera comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don Jose, a naive soldier who is seduced by the wiles of the fiery gypsy Carmen. Jose abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which Jose kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the tragic death of the main character on stage, broke new ground in French opera and were highly controversial. After the premiere, most reviews were critical, and the French public was generally indifferent. Carmen initially gained its reputation through a series of productions outside France, and was not revived in Paris until 1883. Thereafter, it rapidly acquired popularity at home and abroad. Later commentators have asserted that Carmen forms the bridge between the tradition of opera comique and the realism or verismo that characterised late 19th-century Italian opera. The music of Carmen has since been widely acclaimed for brilliance of melody, harmony, atmosphere, and orchestration, and for the skill with which Bizet musically represented the emotions and suffering of his characters....
