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.

Passage: Briarcliff Manor's original settlement was known as Whitson's Corners for brothers John H., Richard, and Reuben Whitson, who owned adjoining farms in the area totaling 400 acres (160 ha). Whitson's Corners was named after the corner of Pleasantville and South State Roads, where John H. Whitson's house, the Crossways, stood from 1820 until the 1940s. The Briarcliff Congregational Church's parish house currently stands at its former location. The neighboring community of Scarborough was known as Weskora until it was renamed in 1864, after resident William Kemey's ancestral hometown in Yorkshire. After the community was incorporated into Briarcliff Manor in 1906, the New York Central and Hudson River Railroad put up a sign reading "Briarcliff West" at the village's Scarborough station. Soon afterward, attributed to the neighborhood's pride over their name, that sign was thrown into the Hudson River and replaced with the original Scarborough sign.Briarcliff Manor derives from "Brier Cliff", a compound of the English words "brier" and "cliff". The name originated in Ireland as that of the family home of John David Ogilby, a professor of ecclesiastical history at the General Theological Seminary. Ogilby had named his New York summer home Brier Cliff after his family home in Ireland. In 1890, Walter Law bought James Stillman's 236-acre (96 ha) Briarcliff Farm and further developed it, later using the name Briarcliff for all his property. Law's friend, Andrew Carnegie, called him "The Laird of Briarcliff Manor"; since the title appealed to all concerned, the village was named "Briarcliff Manor". By 1897, the village post office and railroad station bore the name Briarcliff Manor. The village (and its name) were approved by its residents in a September 12, 1902 referendum; the name prevailed over other suggestions, including "Sing Sing East". On November 21, 1902, the village of Briarcliff Manor was established.The village is also known by several other names. It is conversationally called "Briarcliff", and often erroneously written as "Briar Cliff Manor" (although historically there has been little distinction). The village has been called "Briarcliff on the Hudson" by Mark Twain and Aileen Riggin; it is also known as "the Village of Briarcliff Manor". The name Briarcliff has also been applied to other municipalities, including the 470-person town of Briarcliffe Acres in South Carolina; in naming it, the town's founder had drawn inspiration from Briarcliff Manor's name.
What house now stands were John H. Whitson's house use to be?

Passage: To design and build his ship Nansen chose Colin Archer, Norway's leading shipbuilder and naval architect. Archer was well known for a particular hull design that combined seaworthiness with a shallow draught, and had pioneered the design of "double-ended" craft in which the conventional stern was replaced by a point, increasing manoeuvrability.  Nansen records that Archer made "plan after plan of the projected ship; one model after another was prepared and abandoned". Finally, agreement was reached on a design, and on 9 June 1891 the two men signed the contract.Nansen wanted the ship in one year; he was eager to get away before anyone else could adopt his ideas and forestall him.  The ship's most significant external feature was the roundness of the hull, designed so that there was nothing upon which the ice could get a grip. Bow, stern and keel were rounded off, and the sides smoothed so that, in Nansen's words, the vessel would "slip like an eel out of the embraces of the ice".  To give exceptional strength the hull was sheathed in South American greenheart, the hardest timber available. The three layers of wood forming the hull provided a combined thickness of between 24 and 28 inches (60–70 cm), increasing to around 48 inches (1.25 metres) at the bow, which was further protected by a protruding iron stem. Added strength was provided by crossbeams and braces throughout the length of the hull.
The ship was rigged as a three-masted schooner, with a total sail area of 6,000 square feet (560 m2). Its auxiliary engine of 220 horse-power was capable of speeds up to 7 knots (13 km/h; 8.1 mph). However, speed and sailing qualities were secondary to the requirement of providing a safe and warm stronghold for Nansen and his crew during a drift that might extend for several years, so particular attention was paid to the insulation of the living quarters. At around 400 gross register tonnage, the ship was considerably larger than Nansen had first anticipated, with an overall length of 128 feet (39 m) and a breadth of 36 feet (11 m), a ratio of just over three to one, giving her an unusually stubby appearance. This odd shape was explained by Archer: "A ship that is built with exclusive regard to its suitability for [Nansen's] object must differ essentially from any known vessel." On 6 October 1892, at Archer's yard at Larvik, the ship was launched by Nansen's wife Eva after a brief ceremony. The ship was named Fram, meaning "Forward".
What is the name of the ship that Nansen chose Colin Archer to build?

Passage: The sea offers a very large supply of energy carried by ocean waves, tides, salinity differences, and ocean temperature differences which can be harnessed to generate electricity. Forms of 'green' marine energy include tidal power, marine current power, osmotic power, ocean thermal energy and wave power.
Tidal power uses generators to produce electricity from tidal flows, sometimes by using a dam to store and then release seawater. The Rance barrage, 1 kilometre (0.62 mi) long, near St Malo in Brittany opened in 1967; it generates about 0.5 GW, but it has been followed by few similar schemes.The large and highly variable energy of waves gives them enormous destructive capability, making affordable and reliable wave machines problematic to develop. A small 2 MW commercial wave power plant, "Osprey", was built in Northern Scotland in 1995 about 300 metres (1000 ft) offshore. It was soon damaged by waves, then destroyed by a storm. Marine current power could provide populated areas close to the sea with a significant part of their energy needs. In principle, it could be harnessed by open-flow turbines; sea bed systems are available, but limited to a depth of about 40 metres (130 ft).Offshore wind power is captured by wind turbines  placed out at sea; it has the advantage that wind speeds are higher than on land, though wind farms are more costly to construct offshore. The first offshore wind farm was installed in Denmark in 1991, and the installed capacity of European offshore wind farms reached 3 GW in 2010.Electricity power stations are often located on the coast or beside an estuary so that the sea can be used as a heat sink. A colder heat sink enables more efficient power generation, which is important for expensive nuclear power plants in particular.

What type of power does the Rance barrage provide?
