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.

Question: Passage: Structure 12 lies to the east of Structure 11. It has also been excavated and, like Structure 11, it is covered with rounded boulders held together with clay. It lies to the east of the plaza in the southern area of the Central Group. The structure is a three-tiered platform with stairways on the east and west sides. The visible remains date to the Early Classic but they overlie Late Preclassic construction. A row of sculptures lines the west side of the structure, including six monuments, a stela and an altar. Further monuments line the east side, one of which may be the head of a crocodilian, the others are plain. Sculpture 69 is located on the south side of the structure.Structure 17 is located in the South Group, on the Santa Margarita plantation. It contained a Late Preclassic cache of 13 prismatic obsidian blades.Structure 32 is located near the western edge of the West Group.Structure 34 is in the West Group, at the eastern corner of Terrace 6.Structures 38, 39, 42 and 43 are joined by low platforms on the east side of a plaza on Terrace 7, aligned north–south. Structures 40, 47 and 48 are on south, west and north sides of this plaza. Structures 49, 50, 51, 52 and 53 form a small group on the west side of the terrace, bordered on the north by Terrace 9. Structure 42 is the tallest structure in the North Group, measuring about 11.5 metres (38 ft) high. All of these structures are mounds.Structure 46 is a mound at the edge of Terrace 8 in the North Group and dates from the Terminal Classic through to the Postclassic. The west side of the structure has been cut by a modern road.Structure 54 is built upon Terrace 8, to the north of Structure 46, in the North Group. It is surrounded by an open area without mounds that was probably a mixed residential and agricultural area. It dates from the Terminal Classic through to the Postclassic.Structure 57 is a large mound at the southern limit of the Central Group with an excellent view across the coastal plain. The structure was built in the Late Preclassic and underwent a second phase of construction in the Late Classic. It may have served as a look-out point.

Answer: Which structure dates from the Terminal Classic through to the Postclassic?


Question: Passage: From the time of his earliest recordings in the 1960s, Bowie employed a wide variety of musical styles. His early compositions and performances were strongly influenced by rock and rollers like Little Richard and Elvis Presley, and also the wider world of show business. He particularly strove to emulate the British musical theatre singer-songwriter and actor Anthony Newley, whose vocal style he frequently adopted, and made prominent use of for his 1967 debut release, David Bowie (to the disgust of Newley himself, who destroyed the copy he received from Bowie's publisher). Bowie's music hall fascination continued to surface sporadically alongside such diverse styles as hard rock and heavy metal, soul, psychedelic folk, and pop.Musicologist James Perone observes Bowie's use of octave switches for different repetitions of the same melody, exemplified in his commercial breakthrough single, "Space Oddity", and later in the song "Heroes", to dramatic effect; Perone notes that "in the lowest part of his vocal register ... his voice has an almost crooner-like richness."Voice instructor Jo Thompson describes Bowie's vocal vibrato technique as "particularly deliberate and distinctive". Schinder and Schwartz call him "a vocalist of extraordinary technical ability, able to pitch his singing to particular effect." Here, too, as in his stagecraft and songwriting, the singer's role playing is evident: historiographer Michael Campbell says that Bowie's lyrics "arrest our ear, without question. But Bowie continually shifts from person to person as he delivers them ... His voice changes dramatically from section to section." In a 2014 analysis of 77 "top" artists' vocal ranges, Bowie was 8th, just behind Christina Aguilera and just ahead of Paul McCartney. In addition to the guitar, Bowie also played a variety of keyboards, including piano, Mellotron, Chamberlin, and synthesizers; harmonica; alto and baritone saxophones; stylophone; viola; cello; koto (in the Heroes track "Moss Garden"); thumb piano; drums (on the Heathen track "Cactus"), and various percussion instruments.

Answer: What is the first name of the person who employed a wide variety of musical styles from the time of his earliest recordings?


Question: Passage: The other major fire located in the northern section of the park was the Hellroaring fire. Started in Gallatin National Forest on August 15 from embers from an unattended campfire, the fire initially moved north, but then turned around a few days later and moved south, threatening the area near Tower Junction.In the northwest, the Fan fire started on June 25, and was originally considered a threat to the town of Gardiner, Montana, just outside the park's north entrance. It was the most successfully fought of all the 1988 fires. Though the fire was not contained for a couple of months, by mid-August, it was no longer considered a threat to lives and property.The largest fire in the park was the North Fork fire, both in terms of damage to structures and of area burned. The fire started on July 22, when a man cutting timber dropped his cigarette in Caribou-Targhee National Forest just outside the park's western border. The North Fork fire was the only major fire that was fought from the beginning since it started after the prescribed fire policy was halted on July 15. The fire spread towards the northeast and by the end of the first week of August, was threatening Madison Junction and nearby campground facilities. The fire then raced towards Norris Junction on August 20. Firefighters there used water and foam to keep the structures from being consumed by the blaze. The fire continued its eastward advance along the Yellowstone Plateau, and on August 25, reached visitor facilities at Canyon, where land management agencies and the U.S. military put forth enormous efforts to protect structures. The eastern flank of the fire calmed down for several days, then down-sloping winds off the Yellowstone Plateau forced flames along the west side of the fire towards the town of West Yellowstone, Montana. There, private citizens assisted assigned personnel in soaking hundreds of acres of forestland to protect both the town and an electrical power substation. The fire burned a substantial section of forest along the Madison River valley.

Answer:
What fire was not contained for a couple of months?
