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.

Question: Is the state of the city she grew up in as big in area as the one she later lived in as a girl? Passage:A native of New York City, Aschheim lived in California and Singapore as a girl. She studied art at the University of California, Berkeley, where she received her BA in 1984; in 1987 she received her MFA at the University of California, Davis. In 2003 she became director of the Visual Arts Program at Princeton University, where she began teaching in 1991. During her career she has received fellowships from the New York Foundation for the Arts, the National Endowment for the Arts, the Elizabeth Foundation, and the Pollock-Krasner Foundation, and she has been awarded the Purchase Award and the Richard and Hinda Rosenthal Award, both from the American Academy of Arts and Letters. She received a Guggenheim Fellowship in 2012. In 2017 she was elected an Academician of the National Academy of Design. Aschheim's paintings and drawings are abstract and heavily geometric.

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).

Question: How many siblings did Khalid have in total? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828832, briefly in 841 and again under Caliph al-Wathiq (r. 842845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.
