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.

Question: Passage: In the late 19th and early 20th centuries, child vaudevillian Buster Keaton stays in boarding houses, rides in train boxcars, and performs with his mother and father in a knock-about (physical comedy) act called The Three Keatons. As a young man Keaton travels on his own to Hollywood and tricks his way onto the grounds of silent-film studio Famous Studio as a workman carrying a board, as in one of his trademark comic bits. 
Sneaking onto a set, he attracts the attention of a young casting director, Gloria Brent. He demonstrates his type of physical comedy to a director Kurt Bergner, whom he does not impress. But Gloria recognizes his talent and recommends him to studio head Larry Winters, who offers him a contract. Keaton begins to get small parts in other people's pictures. As his comic talent becomes more apparent and his fame and money-making power grows, he is offered a contract to direct and star in his own silent films.
Dissatisfied with not sharing the profits of his films, he is told that he must invest in his own pictures in order to profit-share. He does in "The Gambler", which is released at the same time as Al Jolson's blockbuster talkie, "The Jazz Singer", reducing public interest in it. Buster struggles to adapt to performing in talking pictures.

Answer: What is the full name of the person who fails to impress Kurt Bergner?


Question: 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.

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