Input: Consider Input: Question: In what city was the person who composed Anna Kraus born? Passage:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".

Input: Consider Input: Question: In what city is the university located from which Marjorie Grene gave another account of the philosophy of biology? Passage:While the overwhelming majority of English-speaking scholars operating under the banner of "philosophy of biology" work within the Anglo-American tradition of analytical philosophy, there is a stream of philosophic work in continental philosophy which seeks to deal with issues deriving from biological science. The communication difficulties involved between these two traditions are well known, not helped by differences in language. Gerhard Vollmer is often thought of as a bridge but, despite his education and residence in Germany, he largely works in the Anglo-American tradition, particularly pragmatism, and is famous for his development of Konrad Lorenz's and Willard Van Orman Quine's idea of evolutionary epistemology. On the other hand, one scholar who has attempted to give a more continental account of the philosophy of biology is Hans Jonas. His "The Phenomenon of Life" (New York, 1966) sets out boldly to offer an "existential interpretation of biological facts", starting with the organism's response to stimulus and ending with man confronting the Universe, and drawing upon a detailed reading of phenomenology. This is unlikely to have much influence on mainstream philosophy of biology, but indicates, as does Vollmer's work, the current powerful influence of biological thought on philosophy. Another account is given by the late Virginia Tech philosopher Marjorie Grene.

Input: Consider Input: Question: Which of these did she work for longer? Passage:During her early career Burrage traveled extensively in Europe, and also visited the Armory Show. She returned to the United States at the outbreak of World War II, moving to Kennebunkport with her sister Madeline, known as "Bob", in 1917, and remaining there until 1947, when they moved to Wiscasset. Her style continued to develop during this time, shifting from the Impressionism of her youth to an abstraction informed by the work of Jackson Pollock; later in life she created collages from mica. Some of her work is influenced by cartography. Active as a preservationist as well as an artist, she served as a director of the National Trust for Historic Preservation, and in 1954 helped to found the Lincoln County Historical Association. She was also involved in the founding of the Maine Art Gallery. Upon her death Burrage was buried with Madeline, who predeceased her, at Evergreen Cemetery in Portland.
