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.

[Q]: Passage: When Thriller and "Billie Jean" were searching to reach their market demographic, MTV and cable TV had a smaller market share than the much larger reach of broadcast television stations in the United States. A national broadcast TV audience on ABC, NBC and CBS affiliate stations, as well as major independent TV stations, was desired by CBS/Epic Records to promote Thriller. The national broadcast TV premiere of the Thriller album's first video, "Billie Jean", was during the week of Halloween in October 1984 and was the idea of Video Concert Hall executive producers Charles Henderson and Jerry Crowe. Video Concert Hall, the first nationwide music video TV network, taped the one-hour special in Hollywood and Atlanta, where the TV studios of Video Concert Hall were located. The Thriller TV special was hosted by Thriller video co-star Vincent Price, distributed by Henderson-Crowe Syndications, Inc. and aired in the top 20 TV markets and much of the United States, including TV stations WNEW (New York), WFLD (Chicago), KTTV (Los Angeles), WPLG (Miami), WQTV (Boston) and WXIA (Atlanta), for a total of 150 TV stations.From the moment Thriller was released, it set the standard for the music industry: artists, record labels, producers, marketers and even choreographers. The music video was ahead of its time and it is considered a monumental one—not only in Jackson's career, but also in the history of pop music. Epic Records' approach to creating a song and video that would appeal to the mass market ended up influencing the way that professionals now market and release their songs. John Landis' production of a mini-movie, rather than the usual short music video, would raise the bar for other directors and producers.
[A]: What music video was ahead of its time and it is considered a monumental one in the history of pop music?


[Q]: Passage: Massenet was a fluent and skilful orchestrator, and willingly provided ballet episodes for his operas, incidental music for plays, and a one-act stand-alone ballet for Vienna (Le carillon, 1892). Macdonald remarks that Massenet's orchestral style resembled that of Delibes, "with its graceful movement and bewitching colour", which was highly suited to classical French ballet. The Méditation for solo violin and orchestra, from Thaïs, is possibly the best known non-vocal piece by Massenet, and appears on many recordings. Another popular stand-alone orchestral piece from the operas is Le dernier sommeil de la Vierge from La Vierge, which has featured on numerous discs since the middle of the 20th century.A Parisian critic, after seeing La grand' tante, declared that Massenet was a symphonist rather than a theatre composer. At the time of the British premiere of Manon in 1885, the critic in The Manchester Guardian, reviewing the work enthusiastically, nevertheless echoed his French confrère's view that the composer was really a symphonist, whose music was at its best when purely orchestral.  Massenet took a wholly opposite view of his talents. He was temperamentally unsuited to writing symphonically: the constraints of sonata form bored him. He wrote, in the early 1870s, "What I have to say, musically, I have to say rapidly, forcefully, concisely; my discourse is tight and nervous, and if I wanted to express myself otherwise I would not be myself." His efforts in the concertante field made little mark, but his orchestral suites, colourful and picturesque according to Grove, have survived on the fringes of the repertoire.  Other works for orchestra are a symphonic poem, Visions (1891), an Ouverture de Concert (1863) and Ouverture de Phèdre (1873). After early attempts at chamber music as a student, he wrote little more in the genre. Most of his early chamber pieces are now lost; three pieces for cello and piano survive.
[A]: What is the name of the best known non-vocal piece by Massenet?


[Q]: Passage: The White Tower is a keep (also known as a donjon), which was often the strongest structure in a medieval castle, and contained lodgings suitable for the lord – in this case, the king or his representative. According to military historian Allen Brown, "The great tower [White Tower] was also, by virtue of its strength, majesty and lordly accommodation, the donjon par excellence". As one of the largest keeps in the Christian world, the White Tower has been described as "the most complete eleventh-century palace in Europe".
The White Tower, not including its projecting corner towers, measures 36 by 32 metres (118 by 105 ft) at the base, and is 27 m (90 ft) high at the southern battlements. The structure was originally three storeys high, comprising a basement floor, an entrance level, and an upper floor. The entrance, as is usual in Norman keeps, was above ground, in this case on the south face, and accessed via a wooden staircase which could be removed in the event of an attack. It was probably during Henry II's reign (1154–1189) that a forebuilding was added to the south side of the tower to provide extra defences to the entrance, but it has not survived. Each floor was divided into three chambers, the largest in the west, a smaller room in the north-east, and the chapel taking up the entrance and upper floors of the south-east. At the western corners of the building are square towers, while to the north-east a round tower houses a spiral staircase. At the south-east corner there is a larger semi-circular projection which accommodates the apse of the chapel.  As the building was intended to be a comfortable residence as well as a stronghold, latrines were built into the walls, and four fireplaces provided warmth.The main building material is Kentish rag-stone, although some local mudstone was also used. Caen stone was imported from northern France to provide details in the Tower's facing, although little of the original material survives as it was replaced with Portland stone in the 17th and 18th centuries. As most of the Tower's windows were enlarged in the 18th century, only two original – albeit restored – examples remain, in the south wall at the gallery level.The tower was terraced into the side of a mound, so the northern side of the basement is partially below ground level. As was typical of most keeps, the bottom floor was an undercroft used for storage. One of the rooms contained a well. Although the layout has remained the same since the tower's construction, the interior of the basement dates mostly from the 18th century when the floor was lowered and the pre-existing timber vaults were replaced with brick counterparts. The basement is lit through small slits.
[A]:
What provided the heating in the White Tower?
