Input: Read this: The Albanian bitumen extraction has a long history and was practiced in an organized way by the Romans. After centuries of silence, the first mentions of Albanian bitumen appeared only in 1868, when the Frenchman Coquand published the first geological description of the deposits of Albanian bitumen. In 1875, the exploitation rights were granted to the Ottoman government and in 1912, they were transferred to the Italian company Simsa. Since 1945, the mine was exploited by the Albanian government and from 2001 to date, the management passed to a French company, which organized the mining process for the manufacture of the natural bitumen on an industrial scale.
Question: When were the exploitation rights given to the Roman Empire?

Output: unanswerable

Input: Read this: During the 1960s the Department of Defense continued to scrutinize the reserve forces and to question the number of divisions and brigades as well as the redundancy of maintaining two reserve components, the Army National Guard and the Army Reserve. In 1967 Secretary of Defense Robert McNamara decided that 15 combat divisions in the Army National Guard were unnecessary and cut the number to 8 divisions (1 mechanized infantry, 2 armored, and 5 infantry), but increased the number of brigades from 7 to 18 (1 airborne, 1 armored, 2 mechanized infantry, and 14 infantry). The loss of the divisions did not set well with the states. Their objections included the inadequate maneuver element mix for those that remained and the end to the practice of rotating divisional commands among the states that supported them. Under the proposal, the remaining division commanders were to reside in the state of the division base. No reduction, however, in total Army National Guard strength was to take place, which convinced the governors to accept the plan. The states reorganized their forces accordingly between 1 December 1967 and 1 May 1968.
Question: How many divisions did the Secretary of Defense cut the original 15 down to?

Output: 8

Input: Read this: Hokkien originated from Quanzhou. After the Opium War in 1842, Xiamen (Amoy) became one of the major treaty ports to be opened for trade with the outside world. From mid-19th century onwards, Xiamen slowly developed to become the political and economical center of the Hokkien-speaking region in China. This caused Amoy dialect to gradually replace the position of dialect variants from Quanzhou and Zhangzhou. From mid-19th century until the end of World War II, western diplomats usually learned Amoy Hokkien as the preferred dialect if they were to communicate with the Hokkien-speaking populace in China or South-East Asia. In the 1940s and 1950s, Taiwan also held Amoy Hokkien as its standard and tended to incline itself towards Amoy dialect.
Question: In what year was South-East Asia war?

Output: unanswerable

Input: Read this: During the Tudor period the Reformation produced a gradual shift to Protestantism, much of London passing from church to private ownership. The traffic in woollen cloths shipped undyed and undressed from London to the nearby shores of the Low Countries, where it was considered indispensable. But the tentacles of English maritime enterprise hardly extended beyond the seas of north-west Europe. The commercial route to Italy and the Mediterranean Sea normally lay through Antwerp and over the Alps; any ships passing through the Strait of Gibraltar to or from England were likely to be Italian or Ragusan. Upon the re-opening of the Netherlands to English shipping in January 1565, there ensued a strong outburst of commercial activity. The Royal Exchange was founded. Mercantilism grew, and monopoly trading companies such as the East India Company were established, with trade expanding to the New World. London became the principal North Sea port, with migrants arriving from England and abroad. The population rose from an estimated 50,000 in 1530 to about 225,000 in 1605.
Question: When was England again able to ship to the Netherlands?

Output:
January 1565
