Please answer this: Given the following context: 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. answer the following question: What is the name of the person who created the green elephants to use as her army to conquer the Emerald City?

Answer: Mombi

Problem: Given the following context: In 1861, Rossier was in Siam, where he assisted the French zoologist Firmin Bocourt by taking ethnographic portraits for the latter's scientific expedition of 18611862, and in 1863, Negretti and Zambra issued a series of 30 stereographic portraits and landscapes taken in Siam that are almost certainly the work of Rossier. In February 1862, Rossier was again in Shanghai, where he sold his cameras and other photographic equipment before embarking for Europe. During his time in Asia it is possible that Rossier photographed in India; Negretti and Zambra issued a series of views of India at about the same time as Rossier's China views.Rossier returned to Switzerland in early 1862 and, in October 1865, married Catharine Barbe Kaelin (18431867). The couple had a son, Christophe Marie Pierre Joseph, who was born on 30 July 1866. Catharine died on 4 April 1867. Rossier maintained a photographic studio in Fribourg until at least 1876 and he also had a studio in Einsiedeln. During the 1860s and 1870s, he produced a number of stereographs and cartes-de-visite comprising portraits and views of Fribourg, Einsiedeln and other places in Switzerland. An 1871 advertisement in the French-language Fribourg newspaper La Liberte offered photographs by Rossier of religious paintings by the artist Melchior Paul von Deschwanden. In 1872, Rossier applied for a passport to travel to France where he may have produced photographs. At some point between 1871 and 1884, he married again. His second wife, Marie Virginie Overney, was employed as a household servant by the landlords of his studio. They had a son, Joseph Louis, who was born in Paris on 16 March 1884, and who went on to own a cafe in Vevey, Switzerland. He died in 1927. Pierre Rossier died in Paris some time between 1883 and 1898.Examples of Rossier's views of Switzerland are held in several institutions and private collections in that country. Rossier took the first commercial photographs of China and Japan, and they are now quite rare. He complained at times of the adverse... answer the following question: What were the two locations where Rossier had a studio?

A: Fribourg

Q: Given the following context: The blacksmith and swordsmith John is tutored at the court of King Arthur, but as a commoner he can't hope to win the hand of Lady Linet, daughter of the Earl of Yeonil. The Earl's castle is attacked by Saracens and Cornishmen disguised as Vikings and his wife is killed, making him lose his memory. The attack was part of a plot by the Saracen Sir Palamides and the pagan Cornish King Mark to overthrow Arthur and Christianity and take over the country, whilst pretending to be Arthur's friends and allies - Palamides is a knight of the round table and Mark has faked his own baptism.John accuses Palamides' servant Bernard of murder before Arthur, who grants him three months' grace to prove the accusation or face execution himself. Another knight, Sir Ontzlake, takes pity on John and trains him in swordplay so that he can take on an alternative secret identity as the wandering Black Knight. The "Vikings" raid a newly founded monastery and take Lady Linet and its monks to Stonehenge for a pagan sacrifice, but the Black Knight arrives and saves her, closely followed by Arthur and his knights, who defeat the pagans and destroy Stonehenge. Sir Palamides tricks the Lady Linet into his castle to try to get her to reveal the Black Knight's identity, but John is informed of this and saves her, still in disguise. Sir Ontzlake then sends him to King Mark's castle, where a pro-Arthur woodcarver shows him a secret tunnel into the royal chambers. John arrives in time to overhear Mark and Palamides finalising their plot but Palamides beats him back to Camelot, tricking Arthur into thinking that the Black Knight is leading the Viking raids. John arrives dressed as the Black Knight and despite revealing his identity is briefly imprisoned until Lady Linet and Sir Ontzlake free him, with the latter standing bail for John to Arthur. answer the following question: Who learns of a secret tunnel to the royal chambers at King Mark's castle?
A:
John
