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: The St. Johns River (Spanish: Río San Juan) is the longest river in the U.S. state of Florida and its most significant one for commercial and recreational use. At 310 miles (500 km) long, it flows north and winds through or borders twelve counties. The drop in elevation from headwaters to mouth is less than 30 feet (9 m); like most Florida waterways, the St. Johns has a very low flow rate 0.3 mph (0.13 m/s) and is often described as "lazy". Numerous lakes are formed by the river or flow into it, but as a river its widest point is nearly 3 miles (5 km) across. The narrowest point is in the headwaters, an unnavigable marsh in Indian River County. The St. Johns drainage basin of 8,840 square miles (22,900 km2) includes some of Florida's major wetlands. It is separated into three major basins and two associated watersheds for Lake George and the Ocklawaha River, all managed by the St. Johns River Water Management District.
A variety of people have lived on or near the St. Johns, including Paleo-indians, Archaic people, Timucua, Mocama, French and Spanish settlers, Seminoles, slaves and freemen, Florida crackers, land developers, tourists and retirees. It has been the subject of William Bartram's journals, Marjorie Kinnan Rawlings' books, and Harriet Beecher Stowe's letters home. Although Florida was the location of the first permanent European settlement in what would become the United States, it was the last U.S. territory on the east coast to be developed; it remained an undeveloped frontier into the 20th century. When attention was turned to the state, however, much of the land was rapidly overdeveloped in a national zeal for progress. The St. Johns, like many Florida rivers, was altered to make way for agricultural and residential centers. It suffered severe pollution and human interference that has diminished the natural order of life in and around the river. In all, 3.5 million people live within the various watersheds that feed into the St. Johns River. The St. Johns, named one of 14 American Heritage Rivers in 1998, was number 6 on a list of America's Ten Most Endangered Rivers in 2008. Restoration efforts are under way for the basins around the St. Johns as Florida continues to deal with population increases in the river's vicinity.
Example Output: What state remained an undeveloped frontier into the 20th century?

Example Input: Passage: Neilston is represented by several tiers of elected government. Neilston Community Council forms the lowest tier of governance whose statutory role is to communicate local opinion to local and central government. It is one of ten community councils of the East Renfrewshire council area. East Renfrewshire Council, the unitary local authority for Neilston, is based at Giffnock, close to the border with the City of Glasgow, and is the executive, deliberative and legislative body responsible for local governance. The Scottish Parliament is responsible for devolved matters such as education, health and justice, while reserved matters are dealt with by the Parliament of the United Kingdom.
The territory of what became Neilston anciently formed part of the Kingdom of Strathclyde. It has lain within the county boundaries of Renfrewshire from a very early time. Neilston emerged as a parish and administrative unit in 1170, and was for many years under the lordship of the Mures of Caldwell whose tombs are at the parish church. The parish was 8 miles (13 km) in length and by from 2 miles (3 km) to 4 miles (6 km) in breadth, encompassing six sevenths of what is now the town of Barrhead. Neilston Parish Council, a local body with limited power, was established in 1895, following the Local Government (Scotland) Act 1894, and abolished in 1930 following the Local Government (Scotland) Act 1929. In 1890, Neilston fell under the authority of Renfrewshire County Council, where it remained until 1975 when the county was superseded by the regional council area of Strathclyde. In 1903, Neilston was within the Paisley Small Debt Court District and Poor Combination. From 1975 to 1996, Neilston was in the Renfrew District of Strathclyde until the two-tier regions and districts of Scotland were abolished. Since 1996 it has formed part of the unitary East Renfrewshire council area; East Renfrewshire Council is the local authority. Neilston remains part of Renfrewshire for purposes of registration and Lieutenancy.
Neilston forms part of the multi member ward 1 of East Renfrewshire Council, namely Neilston, Uplawmoor and Newton Mearns North. Four Councillors are elected using the proportional Single Transferable Vote (STV) system. The current elected members are Charlie Gilbert (Conservative) Paul O'Kane (Labour) Elaine Green (Labour) and Tony Buchanan (SNP).
Neilston is part of the county constituency of East Renfrewshire, electing one MP to the House of Commons of the United Kingdom Parliament. Paul Masterton of the Conservative Party was elected as MP for East Renfrewshire in the 2017 General Election. Before the constituency's creation in 2005, Neilston lay in the Eastwood constituency. For purposes of the Scottish Parliament, Neilston forms part of the Renfrewshire South Constituency, represented by Tom Arthur of the Scottish National Party. In addition to this Neilston is represented by seven regional MSPs from the West of Scotland electoral region.
Example Output: What was established following the Local Government Act in 1894?

Example Input: Passage: Discussion of damming the White River for flood control began in the 1930s, and the U.S. Army Corps of Engineers (CoE) held hearings on building a dam in January 1946. The new dam would create a lake 50 miles (80 km) long, and one arm would extend to Monte Ne. Work on Beaver Dam began in 1960 as the CoE impounded and bought land around the White River. In July 1962, Mary Powell sold Camp Joyzelle to the CoE, and W. T. McWhorten sold his land as well.
The Federal Government required that all cemeteries and burial grounds be moved. This included the Harvey tomb, and it was no easy task. In 1962 contractor Harald Mathis of Springdale took nine days to raze the 40-ton tomb and one to move it. The first attempt broke a flatbed truck. Another contractor from Huntsville with a stronger truck then had to be called in. A new road was laid to the new site of Harvey's tomb. The tomb was placed on the crest of a hill donated by Harvey's longtime friends and neighbors Mr. and Mrs. Kenneth Doescher. Today, the tomb sits on private property visible from the Monte Ne boat launch on Beaver Lake. Relocation of the aging tomb put pressure on it, causing it to crack.The CoE mistakenly believed that the waters of Beaver Lake would cover the area of the large hotels, so those parcels were added to the land they purchased for the project. Dallas Barrack, who owned Oklahoma Row, felt that he had been treated poorly and had received much less than his property was worth. The CoE held a sealed-bid auction and J. G. Gladdens purchased what was left of Missouri and Oklahoma Rows. He planned to move the remnants of Oklahoma Row out of the path of the rising lake waters. In order to do this, it was first necessary to remove the log portion or shell of the hotel. The original windows and doors were dismantled for the move and later reinstalled. The fireplaces, as well as all of the major stonework were later torn down. Also sold at auction were two massive concrete chairs that had been at the base of the amphitheater. They were bought by Mr. and Mrs. Ulis Rose of Rogers and were used to decorate the lawns of their Town and Country restaurant and motel. The chairs are still located in Rogers; however, they now sit unceremoniously in Frisco Park without any plaque or marker indicating their significance. The concrete couch was left in place at the base of the amphitheater, because no one wanted to try to move it.
Example Output:
What is the last name of the couple that bought the two massive concrete chairs at the auction?
