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.

Example Input: Question: Which teacher who taught Torquemada at the convent died first? Passage:There are few firm biographical details concerning Juan de Torquemada, most of which have to be deduced from his own work. Even basic information is subject to uncertainty and controversy. Born at Torquemada, Palencia, north central Spain, at an unknown date before 1566 (Miguel Leon-Portilla argues in detail for 1562) he was brought by his parents to New Spain probably while still a child. He took the Franciscan habit, as is generally agreed, in 1579, and pursued a course of studies in Latin, theology, philosophy and Nahuatl. Brief notices in his own works put him at the convent in Tlacopan in 1582 and (while still a youth) at the convent in Chiauhtla - the presumption being that these relate to his novitiate. It is uncertain if he began his studies at the convento mayor de San Francisco in Mexico City, but it is presumed that part at least of his studies were conducted while resident at the convent of Santiago, Tlatelolco. Among his teachers he names fray Juan Bautista (who taught him theology) and Antonio Valeriano (who taught him Nahuatl and whom he especially praised for his talents). At some time in the early 1580s he was sent by his superiors to Guatemala where he encountered the conquistador Bernal Diaz del Castillo. By 1584 he was certainly at the convent of San Francisco, where he assisted in the infirmary. The conjectured date of his priestly ordination is 1587 or 1588.

Example Input: Question: When was the military force that Mello achieved the rank of Colonel at age 35 founded? Passage:During the same period, he also served as Chief of Public Health for Portuguese India. He undertook a postgraduate course in parasitology in Kaiser Willhelm Institute fuer Biologie, Berlin, and at the Max Planck Institute, Potsdam, Germany from 192223. In 1922, at the age of 35, Mello became a Colonel in the Portuguese Army Medical Corps, achieving the highest rank in the medical military hierarchy of that time, exclusively through merits in the medical campaigns on Public Health which he carried out in Goa, Daman, Diu, and in Angola. Mello was the head of a Portuguese delegation to the World Leprosy Conference in Cuba and is known to have attended at least 40 World Conferences, including the All India Sanitary Conference in Lucknow (1914) and the Third Entomological Meeting in Lucknow (1914) where, at the invitation of the Governor-General of India, he lectured on medical mycology. His researches in tropical medicine brought him international fame and recognition as a world-renowned expert on the subject. Mello published more than 200 research papers on bacteriology in Portuguese, French and English journals. He founded the following medical journals in Goa, Boletim Geral de Medicina, Arquivos Indo-Portugueses de Medicina e Historia Natural, and Arquivos da Escola MedicoCirurgica de Nova Goa. His work in French entitled, A la veille du Centenaire (On the eve of the Centenary) elaborated in great detail the contributions of Goa Medical College during the first hundred years of its establishment. Separate from his medical career, Mello also authored a book in 1946 on the Bengali poet, Rabindranath Tagore entitled O Cantico da Vida na Poesia Tagoreana (The song of life in the poetry of Tagore).

Example Input: Question: Was the original publisher of Journey into Mystery founded before 1953? Passage:Journey into Mystery is an American comic book series initially published by Atlas Comics, then by its successor, Marvel Comics.
