Problem: Given the following context: 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 18611862, 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 (18431867). 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 Liberte 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 cafe 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... answer the following question: What was the first name of the person Rossier married?

A: Catharine

Problem: Given the question: Given the following context: This was followed up by a group of scientists at the College de France in Paris: Frederic Joliot-Curie, Hans von Halban, Lew Kowarski, and Francis Perrin. In February 1939, the Paris Group showed that when fission occurs in uranium, two or three extra neutrons are given off. This important observation suggested that a self-sustaining nuclear chain reaction might be possible. The term "atomic bomb" was already familiar to the British public through the writings of H. G. Wells, in his 1913 novel The World Set Free. It was immediately apparent to many scientists that, in theory at least, an extremely powerful explosive could be created, although most still considered an atomic bomb was an impossibility. Perrin defined a critical mass of uranium to be the smallest amount that could sustain a chain reaction. The neutrons used to cause fission in uranium are considered slow neutrons, but when neutrons are released during a fission reaction they are released as fast neutrons which have much more speed and energy. Thus, in order to create a sustained chain reaction, there existed a need for a neutron moderator to contain and slow the fast neutrons until they reached a usable energy level. The College de France found that both water and graphite could be used as acceptable moderators.Early in 1940, the Paris Group decided on theoretical grounds that heavy water would be an ideal moderator for how they intended to use it. They asked the French Minister of Armaments to obtain as much heavy water as possible from the only source, the large Norsk Hydro hydroelectric station at Vemork in Norway. The French then discovered that Germany had already offered to purchase the entire stock of Norwegian heavy water, indicating that Germany might also be researching an atomic bomb. The French told the Norwegian government of the possible military significance of heavy water. Norway gave the entire stock of 187 litres (41 imp gal; 49 US gal) to a Deuxieme Bureau agent, who secretly brought it to France just before Germany invaded... answer the following question: What country did heavy water come from?

The answer is:
Norway

[Q]: Given the following context: Alice Tate is an upper-class New York housewife, who spends her days shopping, getting beauty treatments, and gossiping with her friends. She has been married to wealthy Doug for fifteen years, and they have two children, who are being raised by a nanny. One day, she has a brief encounter with Joe Ruffalo, a handsome jazz musician.

She also reveals her feelings about Joe. Dr. Yang gives Alice ancient herbs that make her act on her feelings toward Joe Ruffalo. They agree to meet. When the herbs wear off, Alice is appalled at her behavior. She does not go to meet him as planned. The next herbs she receives turn her invisible. She spies on Joe going to visit his ex-wife Vicky. Much to prudish Alice's horror, they make love in Vicky's office. Alice is now glad she did not go to meet Joe.

Alice and Joe finally meet, under the pretense of their children having a 'play-date'. Alice and Joe's meetings become increasingly frequent. answer the following question: What is the first name of the person whose days are spent shopping?
