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: 18 year old Johnnie Simpson lives with his father and Aunt Martha, after his mother died when he was three. His dad is strict with Johnnie and is constantly criticizing him. Johnnie has a girlfriend, Betty Palmer, who works as a waitress at the local drive-in. Maurie Weston, the town bully, owns a fancy hot rod and teases Johnny about him not being allowed to have a car. One night at the drive in, Maurie makes a move on Betty, but she rebuffs his advances, and ends up letting Johnnie drive her home in her brother's car. On the way there, Johnnie gets stopped by the police for speeding and driving recklessly. The police drive him home and give his dad a summons to appear in court with his son. His father berates him for his careless behavior, while Aunt Martha suggests that maybe he should spend more time with his son.
Later, Johnnie gets a summer job at a gas station, without telling his dad. The owner of the station is building a hot rod to race and encourages Johnnie to help him with it. After his father finds out about his new job, he demands that he quit and come to work for him in his real estate office. Later that night, Johnnie and Betty are having dinner together when Maurie again tries to make a move on Betty, and Johnnie gets mad and challenges him to a fight. Maurie suggest that they race instead, and although Johnnie doesn't have a car, he agrees to meet him in an hour. Betty refuses to lend him her brother's car again, so Johnnie asks her to take him to a used car lot where he persuades the salesman to let him test drive a hot rod. Johnnie promises to return the car the next morning.

SOLUTION: What is the full name of the person that Betty Palmer rebuffed thier advances?

PROBLEM: Passage: In 1861, Rossier was in Siam, where he assisted the French zoologist Firmin Bocourt by taking ethnographic portraits for the latter's scientific expedition of 1861–1862, and in 1863, Negretti and Zambra issued a series of 30 stereographic portraits and landscapes taken in Siam that are almost certainly the work of Rossier. In February 1862, Rossier was again in Shanghai, where he sold his cameras and other photographic equipment before embarking for Europe. During his time in Asia it is possible that Rossier photographed in India; Negretti and Zambra issued a series of views of India at about the same time as Rossier's China views.Rossier returned to Switzerland in early 1862 and, in October 1865, married Catharine Barbe Kaelin (1843–1867). The couple had a son, Christophe Marie Pierre Joseph, who was born on 30 July 1866. Catharine died on 4 April 1867.
Rossier maintained a photographic studio in Fribourg until at least 1876 and he also had a studio in Einsiedeln. During the 1860s and 1870s, he produced a number of stereographs and cartes-de-visite comprising portraits and views of Fribourg, Einsiedeln and other places in Switzerland. An 1871 advertisement in the French-language Fribourg newspaper La Liberté offered photographs by Rossier of religious paintings by the artist Melchior Paul von Deschwanden. In 1872, Rossier applied for a passport to travel to France where he may have produced photographs. At some point between 1871 and 1884, he married again. His second wife, Marie Virginie Overney, was employed as a household servant by the landlords of his studio. They had a son, Joseph Louis, who was born in Paris on 16 March 1884, and who went on to own a café in Vevey, Switzerland. He died in 1927.
Pierre Rossier died in Paris some time between 1883 and 1898.Examples of Rossier's views of Switzerland are held in several institutions and private collections in that country. Rossier took the first commercial photographs of China and Japan, and they are now quite rare. He complained at times of the adverse effects of the climate on his photographic chemicals and some of his negatives may have been damaged en route to London from Asia. Though his surviving images are scarce, his importance to the early history of photography in Asia is great. Before his arrival in Japan in 1859, Japanese students of photography had struggled to produce satisfactory images, but Rossier's experience, instruction, and contacts with suppliers of photographic materials were extremely helpful in the development of an autonomous photographic tradition in Japan.

SOLUTION: What was the full name of the person who died on 4 April 1867?

PROBLEM: Passage: Piper reported that as he was leaving Exchange Buildings to return to Houndsditch he saw a man acting suspiciously in the shadows of the cul-de-sac. As the policeman approached him, the man walked away; Piper later described him as being approximately 5 feet 7 inches (1.70 m), pale and fair-haired. When Piper reached Houndsditch he saw two policemen from the adjoining beats—constables Woodhams and Choate—who watched 120 Houndsditch and 11 Exchange Buildings while Piper went to the nearby Bishopsgate Police Station to report. By 11:30 seven uniformed and two plain clothes policemen had gathered in the locality, each armed with his wooden truncheon. Sergeant Bentley from Bishopsgate police station knocked at number 11, unaware that Piper had already done so, which alerted the gang. The door was answered by Gardstein, who made no response when Bentley asked if anyone was working there. Bentley asked him to fetch someone who spoke English; Gardstein left the door half-closed and disappeared inside. Bentley entered the hall with Sergeant Bryant and Constable Woodhams; as they could see the bottom of his trouser legs, they soon realised that someone was watching them from the stairs. The police asked the man if they could step into the back of the property, and he agreed. As Bentley moved forward, the back door opened and one of the gang exited, firing from a pistol as he did so; the man on the stairs also began firing. Bentley was shot in the shoulder and the neck—the second round severing his spine. Bryant was shot in the arm and chest and Woodhams was wounded in the leg, which broke his femur; both collapsed. Although they survived, neither Bryant or Woodhams fully recovered from their injuries.As the gang exited the property and made to escape up the cul-de-sac, other police intervened. Sergeant Charles Tucker from Bishopsgate police station was hit twice, once in the hip and once in the heart by Peters: he died instantly. Choate grabbed Gardstein and wrestled for his gun, but the Russian managed to shoot him in the leg. Other members of the gang ran to Gardstein's assistance, shooting Choate twelve times in the process, but Gardstein was also wounded; as the policeman collapsed, Gardstein was carried away by his accomplices, who included Peters. As these men, aided by an unknown woman, made their escape with Gardstein they were accosted by Isaac Levy, a passer-by, whom they threatened at pistol-point. He was the only witness to the escape who was able to provide firm details; other witnesses confirmed they saw a group of three men and a woman, and thought one of the men was drunk as he was being helped by his friends. The group, which included Peters, went to Svaars' and Peter the Painter's lodgings at 59 Grove Street (now Golding Street), off Commercial Road, where Gardstein was tended by two of the gang's associates, Luba Milstein (Svaars' mistress) and Sara Trassjonsky. As they left Gardstein on the bed, Peters left his Dreyse pistol under the mattress, either to make it seem the wounded man was the one who had killed Tucker, or to enable him to defend himself against a possible arrest.

SOLUTION:
What is the name of the only witness to the escape?
