Input: Read this: The BCG vaccine has limitations, and research to develop new TB vaccines is ongoing. A number of potential candidates are currently in phase I and II clinical trials. Two main approaches are being used to attempt to improve the efficacy of available vaccines. One approach involves adding a subunit vaccine to BCG, while the other strategy is attempting to create new and better live vaccines. MVA85A, an example of a subunit vaccine, currently in trials in South Africa, is based on a genetically modified vaccinia virus. Vaccines are hoped to play a significant role in treatment of both latent and active disease.
Question: What vaccine are researchers trying to improve on?

Output: BCG


Input: Read this: The Pāli Tipitaka, which means "three baskets", refers to the Vinaya Pitaka, the Sutta Pitaka, and the Abhidhamma Pitaka. The Vinaya Pitaka contains disciplinary rules for the Buddhist monks and nuns, as well as explanations of why and how these rules were instituted, supporting material, and doctrinal clarification. The Sutta Pitaka contains discourses ascribed to Gautama Buddha. The Abhidhamma Pitaka contains material often described as systematic expositions of the Gautama Buddha's teachings.
Question: What does the "three baskets" refer to?

Output: the Vinaya Pitaka, the Sutta Pitaka, and the Abhidhamma Pitaka


Input: Read this: 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.
Question: Which group of researchers provided a standard research school environment?

Output: Harrison's group


Input: Read this: In 1997, the mammals were comprehensively revised by Malcolm C. McKenna and Susan K. Bell, which has resulted in the McKenna/Bell classification. Their 1997 book, Classification of Mammals above the Species Level, is the most comprehensive work to date on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of genus, though recent molecular genetic data challenge several of the higher level groupings. The authors worked together as paleontologists at the American Museum of Natural History, New York. McKenna inherited the project from Simpson and, with Bell, constructed a completely updated hierarchical system, covering living and extinct taxa that reflects the historical genealogy of Mammalia.
Question: From whom did McKenna inherit the project from?

Output:
Simpson
