In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Q: Question: How old was Nusslein-Volhard when she won the Nobel Prize in Physiology and Medicine? Passage:The concept of the morphogen has a long history in developmental biology, dating back to the work of the pioneering Drosophila (fruit fly) geneticist, Thomas Hunt Morgan, in the early 20th century. Lewis Wolpert refined the morphogen concept in the 1960s with the French flag model, which described how a morphogen could subdivide a tissue into domains of different target gene expression (corresponding to the colours of the French flag). This model was championed by the leading Drosophila biologist, Peter Lawrence. Christiane Nusslein-Volhard was the first to identify a morphogen, Bicoid, one of the transcription factors present in a gradient in the Drosophila syncitial embryo. She was awarded the 1995 Nobel Prize in Physiology and Medicine for her work explaining the morphogenic embryology of the common fruit fly. Groups led by Gary Struhl and Stephen Cohen then demonstrated that a secreted signalling protein, Decapentaplegic (the Drosophila homologue of transforming growth factor beta), acted as a morphogen during the later stages of Drosophila development.

Q: Question: When was Taylor's place of birth founded? Passage:Taylor was born in 1861 in Peckham, to John and Mary Jane Cash. He worked in stockbroker's office in London and in 1880s he emigrated to South Africa and than to Western Australia in early 1890 following the Ashburton rush. In January 1891, he settled in Southern Cross, where he worked as a merchant and stockbroker. Three years later, he moved his operations at Coolgardie, where a promising gold field had been just discovered. Sitting at the town council, he was elected on 3 August 1896 one of the three members of the Western Australian Legislative Council for the East Province. He was one of the ten Western Australia representatives at the 1897-1898 Australasian Federal Convention, which prepared the federation. He left the council in 1899 to focus on speculative developments. He made estimated 250,000 pounds in speculating in Australia, before moving back to Europe to speculate on London Stock Exchange.

Q: Question: What state was Lucretia Mott laid to rest? Passage:Mrs. Bacon spent her early childhood in New York City and moved to Florida as an adolescent. She went to Antioch College, where she met her husband, Allen Bacon. During World War II, she accompanied her husband to work at Springfield Hospital in Sykesville, Maryland as his assignment for conscientious objector status. She also worked at the American Friends Service Committee for many years and was the inspiration for the rehabilitation of the Fair Hill Burial Ground, a historic Quaker cemetery in North Philadelphia and the final resting place of abolitionists Lucretia Mott and Robert Purvis. Mrs. Bacon authored biographies of both Mott and Purvis. A longtime trustee and Vice President of the Pennsylvania Abolition Society, she wrote a feature article titled "The Pennsylvania Abolition Society's Mission for Black Education" for the Historical Society of Pennsylvania's November 2005 newsletter. She was a founding board member of Women's Way, the country’s oldest and largest funding federation for women’s organizations. Bacon died at her home at Crosslands in Kennett Square, Pennsylvania on February 24, 2011.
