[Q]: Passage: The search for a singer-actress to play Carmen began in the summer of 1873. Press speculation favoured Zulma Bouffar, who was perhaps the librettists' preferred choice. She had sung leading roles in many of Offenbach's operas, but she was unacceptable to Bizet and was turned down by du Locle as unsuitable. In September an approach was made to Marie Roze, well known for previous triumphs at the Opéra-Comique, the Opéra and in London. She refused the part when she learned that she would be required to die on stage. The role was then offered to Célestine Galli-Marié, who agreed to terms with du Locle after several months' negotiation. Galli-Marié, a demanding and at times tempestuous performer, would prove a staunch ally of Bizet, often supporting his resistance to demands from the management that the work should be toned down. At the time it was generally believed that she and the composer were conducting a love affair during the months of rehearsal.The leading tenor part of Don José was given to Paul Lhérie, a rising star of the Opéra-Comique who had recently appeared in works by Massenet and Delibes. He would later become a baritone, and in 1887 sang the role of Zurga in the Covent Garden premiere of Les pêcheurs de perles. Jacques Bouhy, engaged to sing Escamillo, was a young Belgian-born baritone who had already appeared in demanding roles such as Méphistophélès in Gounod's Faust and as Mozart's Figaro. Marguerite Chapuy, who sang Micaëla, was at the beginning of a short career in which she was briefly a star at London's Theatre Royal, Drury Lane; the impresario James H. Mapleson thought her "one of the most charming vocalists it has been my pleasure to know". However, she married and left the stage altogether in 1876, refusing Mapleson's considerable cash inducements to return. 
Question: What is the full name of the person who Mapleson thought to be "one of the most charming vocalists" it had ever been his pleasure to know?
[A]: Marguerite Chapuy.


[Q]: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999). 
Question: What is the full name of the person who was the regular conductor of Ensemble Modern?
[A]: Peter Rundel.


[Q]: Passage: On their way back from whitewater rafting with Juno and Beth, Sarah, along with Sarah's husband Paul and their daughter Jessica, are involved in a car accident when Paul is distracted. Paul and Jessica are killed, but Sarah survives.
One year later, Sarah, Juno, and Beth, as well as friends Sam, Rebecca, and newcomer Holly are reunited at a cabin in the Appalachian Mountains of North Carolina for a spelunking (caving) adventure. The next day, they hike up to a cave entrance and descend. While in the cave, Juno apologises to Sarah for not being there for her after the accident, but Sarah is distant.
After the group moves through a narrow passage, it collapses behind them, trapping them. After a heated discussion, Juno admits that she has led the group into an unknown cave system instead of the fully explored cave system that they had originally planned to visit, and that rescue is, therefore, impossible. She then tells Sarah that she led them into the unknown cave in the hopes of restoring their relationship, but Sarah rebuffs her. 
Question: Who are the people Juno let into an unknown cave system?
[A]:
Sarah.
