TASK DEFINITION: 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.
PROBLEM: Passage: In 1932, a luxury yacht is sailing through a channel off the western coast of South America. The captain is worried about the channel lights not matching the charts, but is quickly dissuaded from changing course by the wealthy passengers for the sake of time, including famous big game hunter and author Bob Rainsford. It is a calm evening, with the cheerful passengers relaxing over drinks and a game of cards. Bob and his companions are debating about whether hunting is at all sporting for the animal being hunted after a friend asks if he would exchange places with a tiger he had recently hunted in Africa. Bob replies that there are two kinds of people in the world: those who hunt and those who are hunted.
The ship suddenly runs aground, causing the ship to take on water and heave violently. Water floods the boiler room, causing the ship to explode and sink into the channel. Rainsford and two others manage to get away and cling to wreckage, but the other survivors are eaten by a shark. He swims to a small, lush island. Wandering through the jungle, he sees the channel lights off the shoreline change, and suspects the ship was deliberately led off course to its doom.
He stumbles across a luxury chateau where he becomes the guest of the expatriate Russian Count Zaroff, a fellow hunting enthusiast. Zaroff remarks that Rainsford's misfortune is not uncommon; in fact, four people from the previous sinking are still staying with him: Eve Trowbridge, her brother Martin, and two sailors.
That night, Zaroff introduces Rainsford to the Trowbridges and reveals his obsession with hunting. During one of his hunts, a Cape buffalo inflicted a head wound on him. He eventually became bored with the sport, to his great consternation, until he discovered "the most dangerous game" on his island. Rainsford asks if he means tigers, but Zaroff denies it.

SOLUTION: What is the last name of the person who becomes a guest at a luxury chateau?

PROBLEM: Passage: Bristol has two major institutions of higher education: the University of Bristol, a redbrick chartered in 1909, and the University of the West of England, opened as Bristol Polytechnic in 1969, which became a university in 1992. The University of Law also has a campus in the city. Bristol has two further education institutions (City of Bristol College and South Gloucestershire and Stroud College) and two theological colleges: Trinity College, and Bristol Baptist College. The city has 129 infant, junior and primary schools,17 secondary schools, and three learning centres. After a section of north London, Bristol has England's second-highest number of independent school places. Independent schools in the city include Clifton College, Clifton High School, Badminton School, Bristol Grammar School, Queen Elizabeth's Hospital (the only all-boys school) and the Redmaids' School (founded in 1634 by John Whitson, which claims to be England's oldest girls' school).
In 2005 Chancellor of the Exchequer Gordon Brown named Bristol one of six English "science cities",
and a £300 million science park was planned at Emersons Green. Research is conducted at the two universities, the Bristol Royal Infirmary and Southmead Hospital, and science outreach is practiced at We The Curious, the Bristol Zoo, the Bristol Festival of Nature and the Create Centre.The city has produced a number of scientists, including 19th-century chemist Humphry Davy (who worked in Hotwells). Physicist Paul Dirac (from Bishopston) received the 1933 Nobel Prize for his contributions to quantum mechanics. Cecil Frank Powell was the Melvill Wills Professor of Physics at the University of Bristol when he received the 1950 Nobel Prize for, among other discoveries, his photographic method of studying nuclear processes. Colin Pillinger was the planetary scientist behind the Beagle 2 project, and neuropsychologist Richard Gregory founded the Exploratory (a hands-on science centre which was the predecessor of At-Bristol/We The Curious).Initiatives such as the Flying Start Challenge encourage an interest in science and engineering in Bristol secondary-school pupils; links with aerospace companies impart technical information and advance student understanding of design.
The Bloodhound SSC project to break the land speed record is based at the Bloodhound Technology Centre on the city's harbourside.

SOLUTION: What is the full name of the physicist from Bristol who won the 1933 Nobel Prize?

PROBLEM: Passage: Santa Anna had successfully escaped towards Vince's Bridge.  Finding the bridge destroyed, he hid in the marsh and was captured the following day. He was brought before Houston, who had been shot in the ankle and badly wounded. Texian soldiers gathered around, calling for the Mexican general's immediate execution.  Bargaining for his life, Santa Anna suggested that he order the remaining Mexican troops to stay away.  In a letter to Filisola, who was now the senior Mexican official in Texas, Santa Anna wrote that "yesterday evening [we] had an unfortunate encounter" and ordered his troops to retreat to Béxar and await further instructions.Urrea urged Filisola to continue the campaign.  He was confident that he could successfully challenge the Texian troops.  According to Hardin, "Santa Anna had presented Mexico with one military disaster; Filisola did not wish to risk another."  Spring rains ruined the ammunition and rendered the roads almost impassable, with troops sinking to their knees in mud.  Mexican troops were soon out of food, and began to fall ill from dysentery and other diseases.  Their supply lines had completely broken down, leaving no hope of further reinforcements. Filisola later wrote that "Had the enemy met us under these cruel circumstances, on the only road that was left, no alternative remained but to die or surrender at discretion".For several weeks after San Jacinto, Santa Anna continued to negotiate with Houston, Rusk, and then Burnet.  Santa Anna suggested two treaties, a public version of promises made between the two countries, and a private version that included Santa Anna's personal agreements.  The Treaties of Velasco required that all Mexican troops retreat south of the Rio Grande and that all private property—code for slaves—be respected and restored.  Prisoners-of-war would be released unharmed, and Santa Anna would be given passage to Veracruz immediately.  He secretly promised to persuade the Mexican Congress to acknowledge the Republic of Texas and to recognize the Rio Grande as the border between the two countries.When Urrea began marching south in mid-May, many families from San Patricio who had supported the Mexican army went with him.  When Texian troops arrived in early June, they found only 20 families remaining.  The area around San Patricio and Refugio suffered a "noticeable depopulation" in the Republic of Texas years.  Although the treaty had specified that Urrea and Filisola would return any slaves their armies had sheltered, Urrea refused to comply. Many former slaves followed the army to Mexico, where they could be free.  By late May the Mexican troops had crossed the Nueces.  Filisola fully expected that the defeat was temporary and that a second campaign would be launched to retake Texas.

SOLUTION:
What is the name of the person who secretly promised to persuade the Mexican Congress to acknowledge the Republic of Texas and to recognize the Rio Grande as the border between the two countries?
