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.

[EX Q]: 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.
[EX A]: Which structure dates from the Terminal Classic through to the Postclassic?

[EX Q]: Passage: The Hudson Valley Rail Trail is a paved 4-mile (6.4 km) east–west rail trail in the town of Lloyd in Ulster County, New York, stretching from the Hudson River through the hamlet of Highland. The trail was originally part of the Poughkeepsie Bridge Route, a rail corridor that crossed the Hudson via the Poughkeepsie Bridge. Controlled by a variety of railroads throughout the 19th and 20th centuries, the bridge was damaged and became unusable after a 1974 fire. By the 1980s the corridor's then-owner, Conrail, had routed all rail traffic in the region north through Selkirk, and was eager to relieve itself of the bridge and adjoining rights-of-way. In 1984, it sold the entire property for one dollar to a felon who did not maintain it or pay taxes on it. The section of the corridor west of the Hudson was seized by Ulster County in 1991 and transferred to the town of Lloyd.
During the 1990s, a broadband utility seeking to lay fiber optic cable paid the town to pass through the former corridor. The town used part of its payment to pave the route and open it as a public rail trail in 1997. The creation of the trail was supported by a local Rotary club, which built a pavilion along the trail. The pavilion includes a donated antique caboose. While the trail originally ended at Route 44–55, it was extended eastward between 2009 and 2010, intersecting Route 9W and continuing to the Poughkeepsie Bridge. The extension was paid for by stimulus funding.
The bridge, now a pedestrian walkway called Walkway Over the Hudson, connects the trail with the Dutchess Rail Trail to the east, creating a 30-mile (48 km) rail trail system that spans the Hudson. The trail is expected to be extended west, where it will border Route 299. As it passes through Highland, the trail is carried by several bridges, connects to four parking areas, and traverses a wetlands complex. The trail forms part of the proposed Empire State Trail.
[EX A]: What is the full name of the structure that was damaged and became unusable after a fire in 1974?

[EX Q]: Passage: Lancaster's career designing for the theatre began and ended with Gilbert and Sullivan. His first costumes and scenery were for the Sadler's Wells Ballet's Pineapple Poll (1951), John Cranko's ballet with a story based on a Gilbert poem and music by Sullivan. His last were for the D'Oyly Carte Opera Company's revival of The Sorcerer (1973). In between, he designed more productions for the Royal Ballet, as well as for Glyndebourne Festival Opera, the Old Vic and the West End. It was a matter of mild regret to him that of the twenty plays, operas and ballets that he designed between the two, only one was for a thoroughly serious piece, Britten's Peter Grimes, for the Bulgarian National Opera in Sofia in 1964.Only two of Lancaster's theatre designs have remained in use in 21st-century productions, both by the Royal Ballet: Pineapple Poll and La fille mal gardée. In an article on the latter in 2016, Danielle Buckley wrote, "Lancaster's surrealist and stylized designs for Fille amplify the story's pantomime quality, and the exaggerated burlesque of its comedy – but the backdrops of fields that roll into the distance, bundles of hay, dreamy skies and village cottages provide the idealized, pastoral context that the story needs". Buckley adds that Lancaster’s designs have been criticised for locating the ballet in no particular time or place – "except, that is, of a 1960s London view of idyllic country life".Lancaster's stated view was that stage sets and costumes should reflect reality, but "through a lens, magnifying and slightly over-emphasising everything which it reflects". Sir Geraint Evans commented on how Lancaster's designs helped the performer: "[His] design for Falstaff was superb: it gave me clues to understanding the character, and reflected that marvellous, subtle sense of humour which was present in all his work.".
[EX A]:
What is the name of the person whose first costumes and scenery were for the Sadler's Wells Ballet's Pineapple Poll?
