In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: As a result of the Berlin Conference of 1884-1885, the Congo Basin is claimed by King Leopold II of the Belgians, who rules the Congo Free State in personal union with the Kingdom of Belgium. The country is on the verge of bankruptcy, Leopold having borrowed huge sums of money to finance the construction of railways and other infrastructure projects. He sends his envoy Léon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred. A tribal leader, Chief Mbonga, offers Rom the diamonds in exchange for an old enemy: Tarzan.
The man once called "Tarzan", John Clayton III, has left Africa behind and settled down in London with his American-born wife, Jane Porter. He took up his birth name and ancestral family residence as Lord Greystoke. In the eight years since returning from Africa, John's story as Tarzan has become legendary among the Victorian public, although John wants to leave that past behind. Through the British Prime Minister, John is invited by King Leopold to visit Boma and report on the development of the Congo by Belgium; he declines to participate in the perceived publicity stunt.

Answer: What is the first name of the person who sends his envoy to secure diamonds?


Question: Passage: Boo-Boo Bear wakes up from winter hibernation, excited about the new Spring. Then Yogi Bear wakes up, his only interest finding some food to eat. Cindy Bear unsuccessfully tries to woo Yogi. After Ranger Smith thwarts Yogi's latest attempts to grab some food, Yogi gets angry and convinces the Ranger to transfer him out of Jellystone National Park. Smith prepares Yogi to be sent over to the San Diego Zoo along with an identification tag. Yogi first says goodbye to everything, but tricks another bear named Corn Pone into going to California instead of him and Boo-Boo and Cindy remain unaware of this, thinking Yogi has departed for good.
Soon, Yogi is stealing food from all over the park under the alter ego "The Brown Phantom", but Smith believes it is another bear. He threatens whoever it is to be sent to the zoo. Cindy, wishing to be with Yogi at the zoo, angers Smith into mistakenly sending her away. However, she gets sent to the St. Louis Zoo instead, as the San Diego Zoo does not need any more bears. When she realizes her true destination, she gets very sad, crying since she knows she would be far from Yogi now.
Late that night, Cindy falls out of the train and becomes lost. A traveling circus is looking for a great act to raise their ratings, when suddenly, their dog runs off and scares Cindy into walking on the telephone wires, the perfect opportunity for the circus.

Answer: What is the name of the character who is sent to the St. Louis zoo?


Question: Passage: Monteverdi's next commission from Mantua came early in 1618, when he was asked to provide the music for Andromeda, an opera based on the ancient Greek myth of the princess chained to a rock. The libretto was written by Duke Ferdinando's chancellor, Ercole Marigliani, and the project was sponsored by the duke's younger brother, Don Vincenzo Gonzaga. It is probable that the work was intended for performance at the Mantua Carnival of March 1618, but as Carter records, Monteverdi's approach to his Mantua commissions was often dilatory and half-hearted; his inability or unwillingness to work on Andromeda delayed its performance, first to 1619 and then to 1620.Monteverdi's letters during the 1618–20 period, mainly to Striggio but occasionally to Don Vincenzo or Marigliani, offer various excuses for his lack of progress on Andromeda, including his duties at St Mark's, his health, and his obligations to provide ceremonial music for the Doge (ruler) of Venice. In February 1619, Monteverdi had started work on another Mantuan project, a ballo (dance with sung parts) to Striggio's libretto entitled Apollo. On 9 January 1620, still with 400 lines of the Andromeda libretto to set to music, Monteverdi proposed to Striggio that the entire opera project be abandoned and the ballo substituted. This idea was rapidly quashed; Don Vincenzo ordered that the remaining Andromeda music be sent to him forthwith. The final segment of Andromeda, an eight-part song, was delivered to Marigliani on 15 February 1620.None of Monteverdi's music for Andromeda has survived. The libretto was also thought to have been lost, until its rediscovery in 1984. As was customary in Monteverdi's time, the manuscript makes no mention of the composer's name—librettos were often the subject of numerous settings by different composers. The libretto's frontispiece confirms that Andromeda was performed during Mantua's Carnival, 1–3 March 1620. An analysis of its contents reveals some influence from Rinuccini's libretto for Arianna, such as use of identical metre and length in the prologues of each work, and several common characters in the respective cast lists. The document remains in private hands and has not been published.Monteverdi recorded no apparent interest in the performance of Andromeda after the 1620 Carnival; the long letter that he wrote to Striggio on 13 March 1620 makes no reference to the event and is chiefly concerned with financial matters. The letter implies that the Gonzaga court was trying to persuade Monteverdi to return to Mantua; in courtly language Monteverdi evades the issue, while comparing the relative generosity of his Venetian employers with the parsimony of the Gonzaga court.

Answer:
What year was a long letter written by the man who provided music for an opera based on a Greek myth chiefly concerned with financial matters?
