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.

Question: Passage: This article is about the residential palace. For the other palace on the same grounds, see Schloss Favorite, Ludwigsburg. For the city, see Ludwigsburg. For the porcelain manufactory, see Ludwigsburg porcelain.
Ludwigsburg Palace (Residenzschloss Ludwigsburg), also known as the "Versailles of Swabia", is a 452-room palace complex of 18 buildings located in Ludwigsburg, Baden-Württemberg, Germany. Its total area, including the gardens, is 32 ha (79 acres)—the largest palatial estate in the country. The palace has four wings: the northern wing, the Alter Hauptbau, is the oldest and was used as a ducal residence; the east and west wings were used for court purposes and housing guests and courtiers; the southern wing, the Neuer Hauptbau, was built to house more court functions and was later used as a residence.
Eberhard Louis, Duke of Württemberg, appointed Philipp Joseph Jenisch to direct the work and construction began in 1704. In 1707, Jenisch was replaced with Johann Friedrich Nette, who completed the majority of the palace and surrounding gardens. Nette died in 1714, and Donato Giuseppe Frisoni finished much of the palace facades. In the final year of construction, Eberhard Louis died and the Neue Hauptbau's interiors were left incomplete. Charles Eugene's court architect, Philippe de La Guêpière, completed and refurbished parts of the New Hauptbau in the Rococo style, especially the palace theatre. Charles Eugene abandoned the palace for Stuttgart in 1775. Duke Frederick II, later King Frederick I, began using Ludwigsburg as his summer residence in the last years of Charles Eugene's reign. Frederick and his wife Charlotte, Princess Royal, resided at Ludwigsburg and employed Nikolaus Friedrich von Thouret to renovate the palace in the Neoclassical style. Thouret converted much of Ludwigsburg's interiors over the reign of Frederick and later life of Charlotte. As a result of each architect's work, Ludwigsburg is a combination of Baroque, Rococo, Neoclassical, and Empire style architecture.
The constitutions of the Free People's State and Kingdom of Württemberg were ratified at Ludwigsburg Palace in 1919 and 1819, respectively. It was the residence for four of Württemberg's monarchs and some other members of the House of Württemberg and their families. The palace was opened to the public in 1918 and then survived World War II intact. It later underwent periods of restoration in the 1950s, 1960s, and 1990s and again for the palace's 300th anniversary in 2004. The palace had more than 350,000 visitors in 2017 and has hosted the Ludwigsburg Festival every year since 1947.
Surrounding the palace are the Blooming Baroque (Blühendes Barock) gardens, arranged in 1954 as they might have appeared in 1800. Nearby is Schloss Favorite, a hunting lodge built in 1717 by Frisoni. Within the palace are two museums operated by the Landesmuseum Württemberg dedicated to fashion and porcelain respectively.

Answer: What is the name of the gardens surrounding the palace that was opened to the public in 1918?


Question: Passage: Scrat is once again trying to bury his acorn but accidentally activates an abandoned alien ship that takes him into deep space, where he unwittingly sends several asteroids en route to a collision with Earth. Meanwhile, Manny and Ellie are preparing upcoming marriage between Peaches and her fiancé, Julian. Diego and his wife Shira want to start a family, but their fierce appearance tends to scare kids. Sid is dumped by his girlfriend, Francine, just as he is about to propose to her, and he laments his solitude. During Manny and Ellie's wedding anniversary party, some of the asteroids strike the place and The Herd barely escape. Meanwhile, at the underground lost world, Buck returns a dinosaur egg back to its rightful owner after it was stolen by a trio of flying dromaeosaurs named Gavin, Gertie, and Roger. Buck discovers an ancient stone pillar and takes it to the surface, where he meets Manny and the others.
Buck explains to The Herd that according to the pillar, the asteroids had caused several extinctions in the past and with a massive one still incoming, he believes that the only place they could find a clue to stop it is on the site of the impact of the previous ones, as according to its engravings, they always fall at the same place. However, the three dromaeosaurs overhear their conversation, and Gavin and Gertie decide to stop them, believing that they could easily avoid the impact, thus not only getting their revenge on Buck, but also killing all mammals and securing domination over Earth for their species. Roger is reluctant, but Gavin and Gertie strong-arm him into cooperating.

Answer: Who is the person that meets Buck on the surface married to?


Question: Passage: Massenet was a prolific composer; he put this down to his way of working, rising early and composing from four o'clock in the morning until midday, a practice he maintained all his life. In general he worked fluently, seldom revising, although Le roi de Lahore, his nearest approach to a traditional grand opera, took him several years to complete to his own satisfaction. It was finished in 1877 and was one of the first new works to be staged at the Palais Garnier, opened two years previously. The opera, with a story taken from the Mahabharata, was an immense success and was quickly taken up by the opera houses of eight Italian cities. It was also performed at the Hungarian State Opera House, the Bavarian State Opera, the Semperoper, Dresden, the Teatro Real in Madrid, and the Royal Opera House, Covent Garden, in London. After the first Covent Garden performance, The Times summed the piece up in a way that was frequently to be applied to the composer's operas: "M. Massenet's opera, although not a work of genius proper, is one of more than common merit, and contains all the elements of at least temporary success."This period was an early high point in Massenet's career. He had been made a chevalier of the Legion of Honour in 1876, and in 1878 he was appointed professor of counterpoint, fugue and composition at the Conservatoire under Thomas, who was now the director. In the same year he was elected to the Institut de France, a prestigious honour, rare for a man in his thirties. Camille Saint-Saëns, whom Massenet beat in the election for the vacancy, was resentful at being passed over for a younger composer. When the result of the election was announced, Massenet sent Saint-Saëns a courteous telegram: "My dear colleague: the Institut has just committed a great injustice". Saint-Saëns cabled back, "I quite agree." He was elected three years later, but his relations with Massenet remained cool.Massenet was a popular and respected teacher at the Conservatoire. His pupils included Bruneau, Charpentier, Chausson, Hahn, Leroux, Pierné, Rabaud and Vidal. He was known for the care he took in drawing out his pupils' ideas, never trying to impose his own. One of his last students, Charles Koechlin, recalled Massenet as a voluble professor, dispensing "a teaching active, living, vibrant, and moreover comprehensive". According to some writers, Massenet's influence extended beyond his own students. In the view of the critic Rodney Milnes, "In word-setting alone, all French musicians profited from the freedom he won from earlier restrictions." Romain Rolland and Francis Poulenc have both considered Massenet an influence on Debussy's Pelléas et Mélisande; Debussy was a student at the Conservatoire during Massenet's professorship but did not study under him.

Answer:
What is the name of the opera that was an immense success and was quickly taken up by the opera houses of eight Italian cities?
