In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: 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?
Example Output: Marguerite Chapuy.

Example Input: Passage: Tchaikovsky remained abroad for a year after the disintegration of his marriage. During this time, he completed Eugene Onegin, orchestrated his Fourth Symphony, and composed the Violin Concerto. He returned briefly to the Moscow Conservatory in the autumn of 1879. For the next few years, assured of a regular income from von Meck, he traveled incessantly throughout Europe and rural Russia, mainly alone, and avoided social contact whenever possible. During this time, Tchaikovsky's foreign reputation grew and a positive reassessment of his music also took place in Russia, thanks in part to Russian novelist Fyodor Dostoyevsky's call for "universal unity" with the West at the unveiling of the Pushkin Monument in Moscow in 1880. Before Dostoyevsky's speech, Tchaikovsky's music had been considered "overly dependent on the West". As Dostoyevsky's message spread throughout Russia, this stigma toward Tchaikovsky's music evaporated. An unprecedented acclaim for him even drew a cult following among the young intelligentsia of Saint Petersburg, including Alexandre Benois, Léon Bakst and Sergei Diaghilev.Two musical works from this period stand out. With the Cathedral of Christ the Saviour nearing completion in Moscow in 1880, the 25th anniversary of the coronation of Alexander II in 1881, and the 1882 Moscow Arts and Industry Exhibition in the planning stage, Nikolai Rubinstein suggested that Tchaikovsky compose a grand commemorative piece. Tchaikovsky agreed and finished it within six weeks. He wrote to Nadezhda von Meck that this piece, the 1812 Overture, would be "very loud and noisy, but I wrote it with no warm feeling of love, and therefore there will probably be no artistic merits in it". He also warned conductor Eduard Nápravník that "I shan't be at all surprised and offended if you find that it is in a style unsuitable for symphony concerts". Nevertheless, the overture became, for many, "the piece by Tchaikovsky they know best"., particularly well-known for the use of cannon in the scores.On 23 March 1881, Nikolai Rubinstein died in Paris. That December, Tchaikovsky started work on his Piano Trio in A minor, "dedicated to the memory of a great artist". First performed privately at the Moscow Conservatory on the first anniversary of Rubinstein's death, the piece became extremely popular during the composer's lifetime; in November 1893, it would become Tchaikovsky's own elegy at memorial concerts in Moscow and St. Petersburg. 
Question: What is the first name of the person who assured Tchaikovsky a regular income which he used to travel incessantly throughout Europe and rural Russia?
Example Output: Nadezhda.

Example Input: Passage: After a tornado in Kansas causes a loose gate to knock Dorothy unconscious, she re-appears in the Land of Oz with Toto, and encounters a talking Signpost (voiced by Jack E. Leonard), whose three signs point in different directions, all marked "Emerald City". They later meet Pumpkinhead (voiced by Paul Lynde), the unwilling servant of antagonist Mombi - cousin of the deceased Wicked Witch of the West. Toto chases a cat to a small cottage where Dorothy is captured by Mombi's pet crow (voiced by Mel Blanc) and Mombi (voiced by Ethel Merman) herself. Pumpkinhead sneaks into the house in Mombi's absence, and discovers her creation of green elephants, to use as her army to conquer the Emerald City. Pumpkinhead frees Dorothy, and they flee. After finding Dorothy gone, Mombi threatens that their warning the Scarecrow will not help when her green elephants "come crashing through the gate".
Dorothy and Pumpkinhead acquire Woodenhead Stallion III (voiced by Herschel Bernardi), a former merry-go-round horse (a combination of the Sawhorse from The Marvelous Land of Oz and the title character of the last Oz book of all, Merry Go Round in Oz), who takes them to the Emerald City, where Dorothy warns the Scarecrow (voiced by Mickey Rooney) about Mombi's green elephants. Mombi arrives moments later, and Toto and the Scarecrow are captured. Dorothy, Pumpkinhead, and Woodenhead flee to Tinland to convince the Tin Man (voiced by Danny Thomas, who spoke, and Larry Storch, who sang) to help them. He declines upon being afraid of the green elephants and suggests that they ask the Cowardly Lion (voiced by Milton Berle), who promises to slay the elephants, but suggests consulting Glinda the Good Witch (voiced by Rise Stevens), who appears to them with a "Glinda Bird" that uses its Tattle Tail to show what is occurring at the palace. She then gives Dorothy a little silver box, to open only in the Emerald City, and only in a dire emergency. 
Question: Who gave Dorothy a little silver box?
Example Output:
Glinda the Good Witch.
