Question: "Which subfield did Pickford's group open?" Context: "Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research." Answer:
Ans: endocrinology

Question: "What is the process of using similar plastic to repair a disc?" Context: "CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs." Answer:
Ans: refilling them with similar refractive plastic or by careful polishing

Question: "With which institution is Rechts der Isar Hospital associated?" Context: "The nine largest and most renowned Technische Universitaten in Germany have formed TU9 German Institutes of Technology as community of interests. Technische Universitaten normally have faculties or departements of natural sciences and often of economics but can also have units of cultural and social sciences and arts. RWTH Aachen, TU Dresden and TU Munchen also have a faculty of medicine associated with university hospitals (Klinikum Aachen, University Hospital Dresden, Rechts der Isar Hospital)." Answer:
Ans: TU Dresden

Question: "The boats operated by the Royal Air Force were what kind and until when?" Context: "In the First World War, Devonport was the headquarters of Western Approaches Command until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force. It was an important embarkation point for US troops for D-Day. The city was heavily bombed by the Luftwaffe, in a series of 59 raids known as the Plymouth Blitz. Although the dockyards were the principal targets, much of the city centre and over 3,700 houses were completely destroyed and more than 1,000 civilians lost their lives. This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II." Answer:
Ans: until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force
