In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Input: Consider Input: Question: Did the chief who predicted the massacre of Mormon towns survive the Black Hawk War? Passage:The Navajo War was not directly a part of the Black Hawk War, but it may have been a source of some of the native warriors who fought in the Black Hawk War. Black Hawk's success drew fighters from other Utes in Colorado, Apaches from New Mexico, and many Navajos. In the winter of 1866 Black Hawk and his band went to the Four Corners region where he received many new recruits. So many Navajos joined him that they formed almost half his raiders. The Navajo had been decimated by the U.S. Army under Kit Carson and forced out of their ancestral homeland. The remaining Navajos were eager for a chance to build up their herds at the expense of white settlers. Manuelito, the most important chief refusing to relocate to the Bosque Redondo Reservation, jointly led Black Hawk's raids on Mormon settlements in southern Utah during 1866. The attacks commenced at Pipe Springs, then a Mormon settlement on the Arizona-Utah border. The retaliation for the Pipe Springs raid left four unarmed Paiutes dead for murders they had nothing to do with. This brought some Paiute fighters to Black Hawk's band. Hopis hearing of the Navajo's movements feared they were to be attacked and struck first ambushing Manuelito's Navajos. The raids continued at the Paria settlements, and Kanab, who sent pleas for help against the raids. In subsequent years, the raids continued in the south by Navajos and Paiutes, which raised tensions to a fever pitch which would result in the worst massacre of the war at Circleville. Chief Kanosh predicted that in 1867 six thousand Navajos would wipe out the Mormon towns in southern Utah.

Input: Consider Input: Question: When was the University that Anne Larigauderie got her Master's Degree in plant molecular biology founded? Passage:Anne Larigauderie received her Master's Degree in plant molecular biology from the Universite Paul Sabatier, Toulouse, France, and her PhD in plant ecology, from the Universite des Sciences et Techniques du Languedoc and the French National Centre for Scientific Research (CNRS) in Montpellier, France. She then spent several years in the USA, working as a research scientist in several scientific projects. In Alaska, for example, she was involved in the first pilot project performing CO2 enrichment of natural ecosystems in the tundra in open top chambers (with Prof. Walter C. Oechel) to understand and predict impact of climate change on plant physiology and ecology. In California (San Diego State University and the University of California Davis) she worked on root competition among California grassland species for soil nutrient pockets (with Prof. Jim Richards). A subsequent project focused on responses of various grass species to various scenarios of elevated CO2 and temperature, the aim of which was to predict response of grasses to future climate change (with Prof. Boyd Strain and Prof. Jim Reynolds, Duke University, North Carolina).

Input: Consider Input: Question: How old was Teymur Bayramalibeyov when his daughter was accepted into her first boarding school? Passage:Maryam Bayramalibeyova was the daughter of Azerbaijani historian and journalist Teymur Bayramalibeyov and his wife Shirin (nee Talyshinskaya), a Russian-educated Talysh-Azerbaijani who translated a number works by classical Russian writers into Azeri and was famous for promoting Western culture in Lankaran and the neighbouring regions. In 1906 Maryam Bayramalibeyova was accepted to the Empress Alexandra Russian Muslim Boarding School for Girls in Baku and 7 years later, to Saint Nina's Secondary Boarding School. In 1917, she graduated from Saint Nina's with honours and was admitted to study medicine at Moscow State University. However, after the October Revolution, being a daughter of an upper-middle class literatus Bayramalibeyova considered her life to be in danger and returned to Lankaran (eventually she did manage to get a post-secondary education receiving an Honours B.A. in law from Baku State University later in 1931). In her native city in 1917, she established the first all-girls secular school (named Uns) in the entire uyezd (administrative unit in Czarist Russia) with the help of Teymur Bayramalibeyov, and became its first principal. The Bayramalibeyovs visited many families in Lankaran encouraging them to send their daughters to Uns. The courses were taught in the Russian language. In order to promote the arts, Maryam Bayramalibeyova organized drama, choir, and musical clubs in the school, which apparently was a success as two of her students later became prominent Azerbaijani actresses and one became a renowned mugham singer. In 1919, Bayramalibeyova founded the Lankaran Women's Charity Association.
