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: 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.

Answer: What is the full name of the structure that was damaged and became unusable after a fire in 1974?


Question: Passage: Holst made some recordings, conducting his own music. For the Columbia company he recorded Beni Mora, the Marching Song and the complete Planets with the London Symphony Orchestra (LSO) in 1922, using the acoustic process. The limitations of early recording prevented the gradual fade-out of women's voices at the end of "Neptune", and the lower strings had to be replaced by a tuba to obtain an effective bass sound. With an anonymous string orchestra Holst recorded the St Paul's Suite and Country Song in 1925. Columbia's main rival, HMV, issued recordings of some of the same repertoire, with an unnamed orchestra conducted by Albert Coates. When electrical recording came in, with dramatically improved recording quality, Holst and the LSO re-recorded The Planets for Columbia in 1926.In the early LP era little of Holst's music was available on disc. Only six of his works are listed in the 1955 issue of The Record Guide: The Planets (recordings under Boult on HMV and Nixa, and another under Sir Malcolm Sargent on Decca); the Perfect Fool ballet music; the St Paul's Suite; and three short choral pieces. In the stereo LP and CD eras numerous recordings of The Planets were issued, performed by orchestras and conductors from round the world. By the early years of the 21st century most of the major and many of the minor orchestral and choral works had been issued on disc. The 2008 issue of The Penguin Guide to Recorded Classical Music contained seven pages of listings of Holst's works on CD. Of the operas, Savitri, The Wandering Scholar, and At the Boar's Head have been recorded.

Answer: What is the last name of the person of whose works only six are listed in the 1955 issue of The Record Guide?


Question: Passage: It was probably William the Conqueror who gave the city and its castle to Bishop Odo of Bayeux, the king's half brother. On William's death in September 1087 his territories were divided between his two sons. Robert, the elder, inherited the title of Duke of Normandy and William Rufus became King of England. A significant number of Norman barons objected to dividing Normandy and England, and Bishop Odo supported Robert's claim to the English throne. Several others, including the earls of Northumberland and Shrewsbury and the Bishop of Coutances came out in support of Robert. Odo prepared Rochester Castle for war and it became one of the headquarters of the rebellion. Its position in Kent made it a suitable base for raids on London and its garrison could harry William's forces in the county. William set off from London and marched towards Rochester to deal with the threat. Before he arrived, news reached the king that Odo had gone to Pevensey Castle, which was under the control of Robert, Count of Mortain. William turned away from Rochester and seized Pevensey. The captured Odo was forced to swear to hand over Rochester to William's men. The king despatched a force with Odo in tow to demand Rochester's surrender. Instead of yielding, the garrison sallied and captured the entire party. In response William laid siege to the city and castle. Contemporary chronicler Orderic Vitalis recorded that the siege began in May 1088. Two siege-castles were built to cut off the city's supply lines and to protect the besiegers from sorties. Conditions within the city were dire: disease was rampant, exacerbated by the heat and flies. The garrison ultimately capitulated and terms were agreed. Odo, Eustace, Count of Boulogne, and Robert de Belleme, son of the Earl of Shrewsbury, were allowed to march away with their weapons and horses but their estates in England were confiscated. This marked the end of the castle's role in the rebellion, and the fortification was probably abandoned shortly afterwards. The siege-castles were abandoned after the conclusion of the siege and have since vanished.After the abandonment of Rochester's first castle it was replaced by another on the current site, in the south-west corner of the town walls. Founded between 1087 and 1089, some parts of the castle survive although it has been much altered by use and reuse in subsequent centuries. William the Conqueror had granted Lanfranc, Archbishop of Canterbury, the manor of Haddenham in Buckinghamshire – which as of the Domesday Survey had an annual income of £40 – for the duration of his life. In turn, the archbishop had granted the manor to Rochester's monks, so on the Conqueror's death Lanfranc and Gundulf, who was appointed Bishop of Rochester in 1077, had to appeal for reconfirmation of the original grant from the new king. William Rufus demanded £100 in exchange for confirmation of the grant. The two bishops felt such a sum was beyond their means and sought a compromise. Instead it was agreed that Gundulf would build a new stone castle at Rochester. Initially the two bishops were concerned that the cost would exceed the king's original request and that they would be responsible for the castle's upkeep. However Henry, Earl of Warwick, convinced them that a castle suitable for the king could be constructed for £40 and that following its completion the castle would be handed over to someone else. The actual cost to Gundulf was £60. The bishop was a skilled architect and supervised the construction of the Tower of London's eponymous White Tower on behalf of William the Conqueror. Gundulf's castle was adjacent to Rochester Cathedral. According to archaeologist Oliver Creighton, when castles were positioned close to churches or cathedrals it suggested a link between the two, and in this case both were owned by the Bishop of Rochester. Often the same craftsmen and architects would work on these closely related buildings, leading to similarities in some of their features. Along with Durham and Old Sarum, Rochester is one of the best examples of a closely linked castle and religious building.
