Problem: Background: Jumbo (about Christmas 1860 - September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in Sudan. Jumbo was exported to Jardin des Plantes, a zoo in Paris and then transferred in 1865 to London Zoo in England. Despite public protest, Jumbo was sold to P. T. Barnum, who took him to the United States for exhibition in March 1882. The giant elephant's name has spawned the common word, "jumbo", meaning large in size.
Context: Jumbo was born at about Christmas 1860 in the Sudan and, after his mother was killed by hunters, the infant Jumbo was captured by Sudanese elephant hunter, Taher Sheriff. The calf was sold to Lorenzo Casanova, an Italian animal dealer and explorer. Casanova transported the animals that he had bought north from Sudan to Suez, and then across the Mediterranean to Trieste.  This collection was sold to Gottlieb Christian Kreutzberg's "Menagerie Kreutzberg" in Germany. Soon after, the elephant was imported to France and kept in the Paris zoo, Jardin des Plantes. In 1865 he was transferred to London Zoo, arriving on 26 June, and becoming famous for giving rides to visitors, especially children. The London zookeeper association leader Anoshan Anathajeyasri gave Jumbo his name; it is likely a variation of one of two Swahili words: jambo, which means "hello"; or jumbe, meaning "chief". If Anoshan Anathajeyasri was from India, it is possible that he named Jumbo after a gigantic rose-apple tree, called jambu (which at that time would be transliterated as 'jumboo')which grows on the mythical Mount Meru and whose fruits were said to be as large as elephants.  While at London, Jumbo broke both tusks, and when they regrew, ground them down against the stonework of his enclosure. His keeper at London was Matthew Scott, whose 1885 autobiography details his life with Jumbo.  Jumbo was sold in February 1882 to the Barnum & Bailey Circus for PS2,000. There was popular objection when Barnum's proposal became known; 100,000 school children wrote to Queen Victoria begging her not to sell the elephant. Despite a lawsuit against the Zoological Gardens alleging the sale was in violation of multiple zoo bylaws, and the zoo's attempt to renege on the sale, the court upheld the sale and Barnum refused to sell Jumbo back. Matthew Scott elected to go with Jumbo to the USA.  In New York, Barnum exhibited the elephant at Madison Square Garden, earning enough in three weeks from the enormous crowds to recoup the money he spent to buy the animal. In the 31-week season, the circus earned $1.75M, largely due to its star attraction. On 30 May 1884, Jumbo was one of Barnum's 21 elephants that crossed the Brooklyn Bridge to prove that it was safe after 12 people died during a stampede caused by mass panic over collapse fears a year earlier.
Question: What was significant about Jumbo compared to other circus elephants?
Answer: While at London, Jumbo broke both tusks, and when they regrew, ground them down against the stonework of his enclosure.

Problem: Background: The Algonquin Round Table was a group of New York City writers, critics, actors, and wits. Gathering initially as part of a practical joke, members of "The Vicious Circle", as they dubbed themselves, met for lunch each day at the Algonquin Hotel from 1919 until roughly 1929. At these luncheons they engaged in wisecracks, wordplay, and witticisms that, through the newspaper columns of Round Table members, were disseminated across the country. Daily association with each other, both at the luncheons and outside of them, inspired members of the Circle to collaborate creatively.
Context: Given the literary and theatrical activities of the Round Table members, it was perhaps inevitable that they would write and stage their own revue. No Sirree!, staged for one night only in April 1922, was a take-off of a then-popular European touring revue called La Chauve-Souris, directed by Nikita Balieff.  No Sirree! had its genesis at the studio of Neysa McMein, which served as something of a salon for Round Tablers away from the Algonquin. Acts included: "Opening Chorus" featuring Woollcott, Toohey, Kaufman, Connelly, Adams and Benchley with violinist Jascha Heifetz providing offstage, off-key accompaniment; "He Who Gets Flapped", a musical number featuring the song "The Everlastin' Ingenue Blues" written by Dorothy Parker and performed by Robert Sherwood accompanied by "chorus girls" including Tallulah Bankhead, Helen Hayes, Ruth Gillmore, Lenore Ulric and Mary Brandon; "Zowie, or the Curse of an Akins Heart"; "The Greasy Hag, an O'Neill Play in One Act" with Kaufman, Connelly and Woollcott; and "Mr. Whim Passes By--An A. A. Milne Play."  The only item of note to emerge from No Sirree! was Robert Benchley's contribution, The Treasurer's Report. Benchley's disjointed parody so delighted those in attendance that Irving Berlin hired Benchley in 1923 to deliver the Report as part of Berlin's Music Box Revue for $500 a week. In 1928, Report was later made into a short sound film in the Fox Movietone sound-on-film system by Fox Film Corporation. The film marked the beginning of a second career for Benchley in Hollywood.  With the success of No Sirree! the Round Tablers hoped to duplicate it with an "official" Vicious Circle production open to the public with material performed by professional actors. Kaufman and Connelly funded the revue, named The Forty-niners. The revue opened in November 1922 and was a failure, running for just 15 performances.
Question: why was it a failure?
Answer:
running for just 15 performances.
