Input: Read this: It is speculated by some archaeologists that Sumerian speakers were farmers who moved down from the north, after perfecting irrigation agriculture there. The Ubaid pottery of southern Mesopotamia has been connected via Choga Mami transitional ware to the pottery of the Samarra period culture (c. 5700 4900 BC C-14) in the north, who were the first to practice a primitive form of irrigation agriculture along the middle Tigris River and its tributaries. The connection is most clearly seen at Tell Awayli (Oueilli, Oueili) near Larsa, excavated by the French in the 1980s, where eight levels yielded pre-Ubaid pottery resembling Samarran ware. According to this theory, farming peoples spread down into southern Mesopotamia because they had developed a temple-centered social organization for mobilizing labor and technology for water control, enabling them to survive and prosper in a difficult environment.[citation needed]
Question: What had the Sumerians perfected before coming south?

Output: irrigation agriculture

QUES: Carnival Tuesday hosts the main events. Full costume is worn, complete with make-up and body paint/adornment. Usually "Mas Boots" that complement the costumes are worn. Each band has their costume presentation based on a particular theme, and contains various sections (some consisting of thousands of revelers) that reflect these themes. The street parade and band costume competition take place. The mas bands eventually converge on the Queen's Park Savannah to pass on "The Stage" for judging. The singer of the most played song is crowned Road March King or Queen earning prize money and usually a vehicle.

QUES: In the diffuse-porous woods, the demarcation between rings is not always so clear and in some cases is almost (if not entirely) invisible to the unaided eye. Conversely, when there is a clear demarcation there may not be a noticeable difference in structure within the growth ring.
What kind of wood often has ring divisions that can't even be seen by looking at it?

ANS: diffuse-porous

New Zealand has a strong hunting culture. The islands making up New Zealand originally had no land mammals apart from bats. However, once Europeans arrived, game animals were introduced by acclimatisation societies to provide New Zealanders with sport and a hunting resource. Deer, pigs, goats, rabbits, hare, tahr and chamois all adapted well to the New Zealand terrain, and with no natural predators, their population exploded. Government agencies view the animals as pests due to their effects on the natural environment and on agricultural production, but hunters view them as a resource.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is New Zealand made up of?
Ah, so.. islands

Question: Mandolin awareness in the United States blossomed in the 1880s, as the instrument became part of a fad that continued into the mid-1920s. According to Clarence L. Partee, the first mandolin made in the United States was made in 1883 or 1884 by Joseph Bohmann, who was an established maker of violins in Chicago. Partee characterized the early instrument as being larger than the European instruments he was used to, with a "peculiar shape" and "crude construction," and said that the quality improved, until American instruments were "superior" to imported instruments. At the time, Partee was using an imported French-made mandolin.
Try to answer this question if possible: When didn't madolin awareness in the US become fluent?
Answer: unanswerable

Problem: The European powers recognized the islands as part of the Spanish East Indies in 1874. However, Spain sold the islands to the German Empire in 1884, and they became part of German New Guinea in 1885. In World War I the Empire of Japan occupied the Marshall Islands, which in 1919 the League of Nations combined with other former German territories to form the South Pacific Mandate. In World War II, the United States conquered the islands in the Gilbert and Marshall Islands campaign. Along with other Pacific Islands, the Marshall Islands were then consolidated into the Trust Territory of the Pacific Islands governed by the US. Self-government was achieved in 1979, and full sovereignty in 1986, under a Compact of Free Association with the United States. Marshall Islands has been a United Nations member state since 1991.
What European nation owned the Marshall Islands in 1874?
