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 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: Vance "Van" Wilder is a confident and sardonic seventh year senior at Coolidge College who is popular among most of the student body. With no ambition to graduate, Van spends his days driving around campus in his customized golf cart, posing nude for figure drawing classes, organizing soirees and fundraisers for his peers. Among his friends are his roommate and close confidant Hutch and his newly hired assistant Taj Badalandabad, a sexually repressed foreign exchange student from India.
Upon learning that his son is still in school, Van's father arrives at Coolidge intent on bringing him home. When Van refuses, his father decides to sever Van's financial support. Faced with disenrollment due to unpaid tuition, Van seeks a payment extension from the registrar, Deloris. After Van has sex with her, Deloris hands him the paperwork for an extension, which Van realizes he only needed to ask for in the first place.
Gwen Pearson works for the school paper, and despite her talents for journalism, her articles do not generate interest from the student body. Her editor assigns her to get an "unattainable" human interest story on Van Wilder as he normally refuses to do interviews for the paper. After a couple of attempts to get money fast, Van is approached by the Lambda Omega Omega fraternity, offering to pay him a thousand dollars to throw them a blowout party and boost their popularity.
Overhearing two of the Lambdas expressing their excitement over the party's success and their satisfaction with Van's work, Gwen writes a story crediting Van as the host of the party. Though Van hates the article at first, he realizes it can be the "cash cow" he needs to stay in school. Van eventually agrees to sit down with Gwen for the follow-up piece after losing a hockey bet to her.

SOLUTION: What is the full name of the person whose friends are his roommate and newly hired assistant?

PROBLEM: Passage: Donald Duck is doing some camouflage painting on a cannon with yellow, green, and red stripes and black dots (based on the colors of the Flag of Lithuania with bullet holes in it). Sergeant Pete sees it and scolds Donald, explaining that it needs to painted so it can't be seen.  Pete then demands that Donald re-paint the cannon to make it "hard to see".  Obliging to the sergeant's orders, Donald walks to the "Experimental Laboratory: Camouflage Corps", disregarding the 'keep out' sign, and walks in. He finds some "invisible paint", which he tests with his finger, and uses it to paint the cannon.
When Pete returns, he is shocked to find the cannon seemingly gone, believing it to be stolen.  But of course it isn't stolen, as the sergeant finds out the hard way by bonking his head on the underside of the cannon and discovering Donald inside.  Angered that Donald painted the cannon too invisible to see, Pete blows hard into one end of the barrel, sending Donald out the other end and into the bucket of invisible paint.  When Donald runs away, Pete finds out Donald has become invisible after seeing Donald's footprints on the ground.  Donald then swims across a lake, but the invisible paint doesn't come off.
Pete continues to chase Donald through a field of flowers, until he accidentally throws some of the flowers on Donald, revealing his outline.  Pete spots Donald and tries to catch him, but he gets away again.  However, this gives Pete an idea to find Donald.  When the General drives up, Pete's antics, including jumping around a tree while singing "Here We Go Round The Mulberry Bush" and throwing flowers, convinces the General that he is acting odd, especially after he asks the General "did you see a little guy that you can't see?"  The invisible Donald then puts a cactus down Pete's pants, making him scream in pain and jump around like a madman, making the General wonder what is going on with Pete.

SOLUTION:
Who hits his head on the cannon?
