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.

Example Input: Passage: Before the album's release, M.I.A. said that audiences found it hard to dance to political songs. This made her keen to produce music that sounded like pop but addressed important issues.  "Sunshowers", with its lyrical references to snipers, murder and the PLO, was written in response to the Tamil Tigers being considered terrorists in some quarters. She said, "you can't separate the world into two parts like that, good and evil. America has successfully tied all these pockets of independence struggles, revolutions and extremists into one big notion of terrorism." The lyrics caused controversy; MTV censored the sounds of gunshots in the song and MTV US refused to broadcast the video unless a disclaimer that disavowed the lyrics was added. The BBC described the lyrics as "always fluid and never too rhetorical" and sounding like "snatches of overheard conversation". The songs deal with topics ranging from sex to drug dealing.Musically, the album incorporates elements of baile funk, grime, hip hop, and ragga. Peter Shapiro, writing in The Times, summed up the album's musical influences as "anything as long as it has a beat". Some tracks drew on Tamil film music, which M.I.A. listened to while growing up. Shapiro described her music as a "multi-genre pile-up" and likened it to her graphic art, calling it "vivid, gaudy, lo-fi and deceptively candyfloss". In a 2005 interview, when asked about the difficulty in categorising her sound, M.I.A. explained, "Influences are crossing over into each other's puddles. I just accept where I'm at, I accept where the world is at and I accept how we receive and digest information. I get that somebody in Tokyo is on the internet instant messaging, and someone in the favelas is on the internet. Everybody seems to know a little bit about everything and that's how we process information now. This just reflects that.".
Example Output: What year did the artist who released the song "Sunshowers" say in an interview "I just accept where I'm at"?

Example Input: Passage: In December 1775, Cletus Moyer is a free black Northerner in colonial America, working with a pre-Underground Railroad network to help slaves escape captivity. In the days just prior to Christmas, a group of bounty hunters led by Hattie Carraway captures Moyer near the Parker plantation in Spotsylvania County, Virginia. Because of his capture, dozens of slaves who have already left their plantations in escape attempts are in danger of being captured as well. Moyer implores two slaves from the nearby Reynolds plantation to take his place: Kunta Kinte, a Mandinka in his mid-twenties who was captured in what is now the Gambia, and Fiddler, an elderly man who was born into slavery. Kunta is eager to help (and to escape himself), but Fiddler is unwilling, fearful of the consequences if they are caught.
After an unsuccessful slave revolt elsewhere in the colony, Moyer and two slaves are hanged by Carraway's men on Christmas Eve, prompting Fiddler to set aside his fear and help Kunta lead the runaway slaves to freedom. Although the pair successfully leads the runaways that night to their next stop on the escape route (a boat waiting at the river) there is only room for one of them, and since neither one wants to go without the other, they both decide to stay.  That choice forces them to return to the Parker plantation and manufacture an excuse for their temporary absence. Nevertheless, Kunta and Fiddler are left with the satisfaction of knowing that they helped to give a group of fellow slaves the best Christmas gift of all: freedom.
Example Output: What's the first name of the person who dies the day before Christmas?

Example Input: Passage: The current entrance in the north-east occupies the approximate location of the main gatehouse constructed by Gundulf and then rebuilt during 1249–1250. It was pulled down in the 1870s when the enclosure was converted into a municipal garden. An engraving from 1735 by the Buck brothers gives some indication of the gatehouse's form: the gate was an archway between two towers projecting from the curtain wall. It was reached by a stone causeway across a ditch, rather than a drawbridge. A tower containing a postern gate was located in the north-west corner of the enclosure, built at the close of the 14th century to guard the bridge over the Medway. The tower and postern no longer stands, but 19th-century antiquary and engineer G. T. Clark made some notes on the structure while it was still standing and commented that it had mechanisms to lift supplies for the castle from the river. The western part of the stone outer wall, a stretch facing the river, dates from when Gundulf built the first wall enclosing the castle. In the 19th century a revetment was added to strengthen the decaying wall. Like the keep, it was constructed using Kentish Ragstone. This part of Gundulf's wall was 4.5 feet (1.4 m) thick at the base, narrowing to 2 feet (0.61 m) at the top; it rose to a height of around 22 feet (6.7 m). Four embrasures were added to this part of the wall in the 13th century, although the builders imitated Norman design. At the northern end of the 12th-century stretch of western wall are the remains of a building, probably a hall, dating from the 13th century. Although no longer standing, it is known it had a vaulted undercroft.In the south Gundulf's wall survived into the modern period, although has now been dismantled. The current wall is a 19th-century replacement. At the eastern end of this wall, near the southern corner of the castle, is a two-storey rounded tower 30 feet (9.1 m) in diameter dating from the early 13th century. It was built to fill the breach in the curtain wall caused when John's army besieged the castle and to reinforce a weak point in the defences. The section from the tower to the location of the former main gatehouse in the north-east dates from about 1367 to 1370. Two towers were built along the wall, each two storeys high and again using Kentish Ragstone. The one nearest the keep is relatively plain and the northernmost one more elaborate. The latter was intended for use as a residence and in the modern period was converted into a cottage. The wall between these two towers was reduced in the modern period, possibly to give a better view of the cathedral. Apart from the west side, the castle was surrounded by a ditch, much of which has since been filled in.
Example Output:
What was built to reinforce a weak point in the defences of the castle?
