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.

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.

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

Passage: The situation reached a crisis on May 7, 1963. Breakfast in the jail took four hours to distribute to all the prisoners. Seventy members of the Birmingham Chamber of Commerce pleaded with the protest organizers to stop the actions. The NAACP asked for sympathizers to picket in unity in 100 American cities. Twenty rabbis flew to Birmingham to support the cause, equating silence about segregation to the atrocities of the Holocaust. Local rabbis disagreed and asked them to go home. The editor of The Birmingham News wired President Kennedy and pleaded with him to end the protests.
Fire hoses were used once again, injuring police and Fred Shuttlesworth, as well as other demonstrators. Commissioner Connor expressed regret at missing seeing Shuttlesworth get hit and said he "wished they'd carried him away in a hearse". Another 1,000 people were arrested, bringing the total to 2,500.
News of the mass arrests of children had reached Western Europe and the Soviet Union. The Soviet Union devoted up to 25 percent of its news broadcast to the demonstrations, sending much of it to Africa, where Soviet and U.S. interests clashed. Soviet news commentary accused the Kennedy administration of neglect and "inactivity". Alabama Governor George Wallace sent state troopers to assist Connor.  Attorney General Robert Kennedy prepared to activate the Alabama National Guard and notified the Second Infantry Division from Fort Benning, Georgia that it might be deployed to Birmingham.No business of any kind was being conducted downtown. Organizers planned to flood the downtown area businesses with black people. Smaller groups of decoys were set out to distract police attention from activities at the 16th Street Baptist Church. Protesters set off false fire alarms to occupy the fire department and its hoses. One group of children approached a police officer and announced, "We want to go to jail!" When the officer pointed the way, the students ran across Kelly Ingram Park shouting, "We're going to jail!" Six hundred picketers reached downtown Birmingham. Large groups of protesters sat in stores and sang freedom songs. Streets, sidewalks, stores, and buildings were overwhelmed with more than 3,000 protesters. The sheriff and chief of police admitted to Burke Marshall that they did not think they could handle the situation for more than a few hours.

Ex Output:
What is the first name of the person Commissioner Connor said he wished they'd carried away in a hearse?

Passage: The Treaty of San Stefano was signed on 3 March 1878 by Russia and the Ottoman Empire. It was to set up an autonomous Bulgarian principality spanning Moesia, Macedonia and Thrace, roughly on the territories of the Second Bulgarian Empire, and this day is now a public holiday called National Liberation Day. The other Great Powers immediately rejected the treaty out of fear that such a large country in the Balkans might threaten their interests. It was superseded by the Treaty of Berlin, signed on 13 July, which provided for a much smaller state only comprising Moesia and the region of Sofia, leaving large populations of ethnic Bulgarians outside the new country. This significantly contributed to Bulgaria's militaristic foreign affairs approach during the first half of the 20th century.The Bulgarian principality won a war against Serbia and incorporated the semi-autonomous Ottoman territory of Eastern Rumelia in 1885, proclaiming itself an independent state on 5 October 1908. In the years following independence, Bulgaria increasingly militarized and was often referred to as "the Balkan Prussia". It became involved in three consecutive conflicts between 1912 and 1918—two Balkan Wars and World War I. After a disastrous defeat in the Second Balkan War, Bulgaria again found itself fighting on the losing side as a result of its alliance with the Central Powers in World War I. Despite fielding more than a quarter of its population in a 1,200,000-strong army and achieving several decisive victories at Doiran and Monastir, the country capitulated in 1918. The war resulted in significant territorial losses and a total of 87,500 soldiers killed. More than 253,000 refugees from the lost territories immigrated to Bulgaria from 1912 to 1929, placing additional strain on the already ruined national economy.

Ex Output:

What day is now a public holiday called National Liberation Day?
