Input: Question: When was the prize Ian competed for in 1974 first given out? Passage 1:Thomson came from a footballing family: his father Jim and brother Gary were both Balmain players. His uncle, Allan Thomson was an Australian international. Ian played President's Cup for Balmain in 1974. He then spent two seasons with Quanbeyan under coach Don Furner, earning representative honours with Country Firsts in 1976. He returned to Sydney, signing with Manly-Warringah for the 1977 NSWRFL season. The following year he represented New South Wales and was first selected to play for Australia in the first test against New Zealand. The 1978 NSWRFL season's Grand Final was to be played by the Manly-Warringah and Cronulla-Sutherland clubs. The game ended in a draw and resulted in a re-play which was won by Manly-Warringah, with Thomson playing in both matches. After that he went on the 1978 Kangaroo tour.
 Passage 2:The sixth story, "Angira" (Taxila 1800 BC), is about a man who wants to save the Aryan race from losing its identity to other races by teaching about their true culture (precursor to Vedic Rishis). The eighth story (Pravahan (700 BC. Panchala, U.P.). is about the upper class manipulating religion for their own vested interests and conspiring to keep people in dark for at least 2000 years). One can see how easily and frequently the Indians, the mid easterners and the Greeks mingled with each other in the times of Chanakya and Alexander by reading the tenth story Nagdatt, which is about a philosopher classmate of Chanakya who travels to Persia and Greece and learns how Athens fell to Macedonia. The eleventh story (Prabha, 50 AD) is about the famous (also the first Indian) dramatist Aśvaghoṣa, who adopted the Greek art of drama into Indian culture in a very beautiful and authentic way, and his inspiration. Baba Noordeen (1300), the 15th story is about the rise of Sufism. The seventeenth story Rekha Bhagat (1800 is about the barbarous rule of the East India company and the anarchy it brought to parts of India. The last story ("Sumer", 1942) is about a man who goes on to fight the Japanese because he wants Soviet Russia to triumph, for this nation according to him is the only hope left for humanity.
 Passage 3:Nathan Oram Kaplan (June 25, 1917 – April 15, 1986) was an American biochemist who studied enzymology and chemotherapy. After completing a B.A. in chemistry at UCLA in 1939, Kaplan studied carbohydrate metabolism in the liver under David M. Greenberg at the University of California, Berkeley medical school. He earned his Ph.D. in 1943. From 1942 to 1944, Kaplan participated in the Manhattan Project, and then spent a year as an instructor at Wayne State University. From 1945 to 1949, Kaplan worked with Fritz Lipmann at Massachusetts General Hospital to study coenzyme A. Kaplan went to the University of Illinois College of Medicine as an assistant professor in 1949, and from 1950 to 1957 he worked at the McCollum-Pratt Institute of Johns Hopkins University. In 1957, he was recruited to head a new graduate program in biochemistry at Brandeis University. In 1968, Kaplan moved to the University of California, San Diego, where he studied the role of lactate dehydrogenase in cancer. He also founded a colony of nude mice, a strain of laboratory mice useful in the study of cancer and other diseases. In 1981, Kaplan became a founding member of the World Cultural Council.
