Example Input: Passage: IBM also had their own DBMS in 1966, known as Information Management System (IMS). IMS was a development of software written for the Apollo program on the System/360. IMS was generally similar in concept to CODASYL, but used a strict hierarchy for its model of data navigation instead of CODASYL's network model. Both concepts later became known as navigational databases due to the way data was accessed, and Bachman's 1973 Turing Award presentation was The Programmer as Navigator. IMS is classified[by whom?] as a hierarchical database. IDMS and Cincom Systems' TOTAL database are classified as network databases. IMS remains in use as of 2014[update]. Question: What was the name of Bachman's Turing Award presentation in 1973?
Example Output: The Programmer as Navigator

Example Input: Passage: Due to the inter-communal ethnic tensions between 1963 and 1974, an island-wide census was regarded as impossible. Nevertheless, the Greek Cypriots conducted one in 1973, without the Turkish Cypriot populace. According to this census, the Greek Cypriot population was 482,000. One year later, in 1974, the Cypriot government's Department of Statistics and Research estimated the total population of Cyprus at 641,000; of whom 506,000 (78.9%) were Greeks, and 118,000 (18.4%) Turkish. After the partition of the island in 1974, Greeks conducted four more censuses: in 1976, 1982, 1992 and 2001; these excluded the Turkish population which was resident in the northern part of the island. Question: What was the number of Greek Cypriots on Cyprus in 1973?
Example Output:
482,000
