Input: Read this: As the Ottoman Empire gradually shrank in size, some 7–9 million Turkish-Muslims from its former territories in the Caucasus, Crimea, Balkans, and the Mediterranean islands migrated to Anatolia and Eastern Thrace. After the Empire lost the Balkan Wars (1912–13), it lost all its Balkan territories except East Thrace (European Turkey). This resulted in around 400,000 Muslims fleeing with the retreating Ottoman armies (with many dying from cholera brought by the soldiers), and with some 400,000 non-Muslims fleeing territory still under Ottoman rule. Justin McCarthy estimates that during the period 1821 to 1922 several million Muslims died in the Balkans, with the expulsion of a similar number.
Question: How many Muslims fled the Balkans with the Ottoman armies?

Output: 400,000


Input: Read this: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.
Question: What type of music did many of the post-punk bands start indulging in?

Output: pop


Input: Read this: The Sumerians developed a complex system of metrology c. 4000 BC. This advanced metrology resulted in the creation of arithmetic, geometry, and algebra. From c. 2600 BC onwards, the Sumerians wrote multiplication tables on clay tablets and dealt with geometrical exercises and division problems. The earliest traces of the Babylonian numerals also date back to this period. The period c. 2700 – 2300 BC saw the first appearance of the abacus, and a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system. The Sumerians were the first to use a place value numeral system. There is also anecdotal evidence the Sumerians may have used a type of slide rule in astronomical calculations. They were the first to find the area of a triangle and the volume of a cube.
Question: What were the Sumerians the first to do when it came to mathematics?

Output: use a place value numeral system


Input: Read this: In response to a given problem situation (), a number of competing conjectures, or tentative theories (), are systematically subjected to the most rigorous attempts at falsification possible. This process, error elimination (), performs a similar function for science that natural selection performs for biological evolution. Theories that better survive the process of refutation are not more true, but rather, more "fit"—in other words, more applicable to the problem situation at hand (). Consequently, just as a species' biological fitness does not ensure continued survival, neither does rigorous testing protect a scientific theory from refutation in the future. Yet, as it appears that the engine of biological evolution has, over many generations, produced adaptive traits equipped to deal with more and more complex problems of survival, likewise, the evolution of theories through the scientific method may, in Popper's view, reflect a certain type of progress: toward more and more interesting problems (). For Popper, it is in the interplay between the tentative theories (conjectures) and error elimination (refutation) that scientific knowledge advances toward greater and greater problems; in a process very much akin to the interplay between genetic variation and natural selection.
Question: What theories are less applicable to the situation at hand?

Output:
unanswerable
