Input: Read this: CSL, one of the world's top five biotech companies, and Sigma Pharmaceuticals have their headquarters in Melbourne. The two are the largest listed Australian pharmaceutical companies. Melbourne has an important ICT industry that employs over 60,000 people (one third of Australia's ICT workforce), with a turnover of $19.8 billion and export revenues of $615 million. In addition, tourism also plays an important role in Melbourne's economy, with about 7.6 million domestic visitors and 1.88 million international visitors in 2004. In 2008, Melbourne overtook Sydney with the amount of money that domestic tourists spent in the city, accounting for around $15.8 billion annually. Melbourne has been attracting an increasing share of domestic and international conference markets. Construction began in February 2006 of a $1 billion 5000-seat international convention centre, Hilton Hotel and commercial precinct adjacent to the Melbourne Exhibition and Convention Centre to link development along the Yarra River with the Southbank precinct and multibillion-dollar Docklands redevelopment.
Question: Domestic visitors spend about how much money in the city of Melbourne annually?

Output: $15.8 billion

Input: Read this: The bacterial cell is surrounded by a cell membrane (also known as a lipid, cytoplasmic or plasma membrane). This membrane encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of the cytoplasm within the cell. As they are prokaryotes, bacteria do not usually have membrane-bound organelles in their cytoplasm, and thus contain few large intracellular structures. They lack a true nucleus, mitochondria, chloroplasts and the other organelles present in eukaryotic cells. Bacteria were once seen as simple bags of cytoplasm, but structures such as the prokaryotic cytoskeleton and the localization of proteins to specific locations within the cytoplasm that give bacteria some complexity have been discovered. These subcellular levels of organization have been called "bacterial hyperstructures".
Question: What is a cell membrane?

Output: lipid

Input: Read this: The value of the U.S. dollar was therefore no longer anchored to gold, and it fell upon the Federal Reserve to maintain the value of the U.S. currency. The Federal Reserve, however, continued to increase the money supply, resulting in stagflation and a rapidly declining value of the U.S. dollar in the 1970s. This was largely due to the prevailing economic view at the time that inflation and real economic growth were linked (the Phillips curve), and so inflation was regarded as relatively benign. Between 1965 and 1981, the U.S. dollar lost two thirds of its value.
Question: What was the value of the U.S. dollar no longer anchored to?

Output: gold

Input: Read this: The Football League was founded in 1888, 16 years after the first FA Cup competition. Since the creation of The Football League, Tottenham Hotspur is the only non-league "giant-killer" to win the Cup, taking the 1901 FA Cup with a victory over reigning league runners-up Sheffield United: although at that time, there were only two divisions and 36 clubs in the Football League, and Spurs were champions of the next lowest football tier - the Southern League and probably already good enough for the First Division (as was shown when they joined the Second Division in 1908 and immediately won promotion to the First.) Only two other actual non-League clubs have even reached the final since the founding of the League: Sheffield Wednesday in 1890 (champions of the Football Alliance, a rival league which was already effectively the Second Division, which it formally became in 1892 Wednesday being let straight into the First Division), and Southampton in 1900 and 1902 (in which years they were also Southern League champions, proving the strength of that league: again, they were probably of equivalent standard to a First Division club at the time, but Southampton's form subsequently faded and they did not join the League till 1920 and the formation of the Third Division.)
Question: Who won the FA Cup in 1888?
