Problem: The Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty (c. 1050256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618907 AD). The period saw a number of limited institutional innovations. To pay for its military campaigns and the settlement of newly conquered frontier territories, the government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han period. Science and technology during the Han period saw significant advances, including papermaking, the nautical steering rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer employing an inverted pendulum.
What industry did the government use to help pay for its military campaigns?

Answer: iron

Problem: Traditional willow growing and weaving (such as basket weaving) is not as extensive as it used to be but is still carried out on the Somerset Levels and is commemorated at the Willows and Wetlands Visitor Centre. Fragments of willow basket were found near the Glastonbury Lake Village, and it was also used in the construction of several Iron Age causeways. The willow was harvested using a traditional method of pollarding, where a tree would be cut back to the main stem. During the 1930s more than 3,600 hectares (8,900 acres) of willow were being grown commercially on the Levels. Largely due to the displacement of baskets with plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 140 hectares (350 acres) were grown commercially, near the villages of Burrowbridge, Westonzoyland and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially.

Problem: The brief peace in Europe allowed Napoleon to focus on the French colonies abroad. Saint-Domingue had managed to acquire a high level of political autonomy during the Revolutionary Wars, with Toussaint Louverture installing himself as de facto dictator by 1801. Napoleon saw his chance to recuperate the formerly wealthy colony when he signed the Treaty of Amiens. During the Revolution, the National Convention voted to abolish slavery in February 1794. Under the terms of Amiens, however, Napoleon agreed to appease British demands by not abolishing slavery in any colonies where the 1794 decree had never been implemented. The resulting Law of 20 May never applied to colonies like Guadeloupe or Guyane, even though rogue generals and other officials used the pretext of peace as an opportunity to reinstate slavery in some of these places. The Law of 20 May officially restored the slave trade to the Caribbean colonies, not slavery itself. Napoleon sent an expedition under General Leclerc designed to reassert control over Sainte-Domingue. Although the French managed to capture Toussaint Louverture, the expedition failed when high rates of disease crippled the French army. In May 1803, the last 8000 French troops left the island and the slaves proclaimed an independent republic that they called Haiti in 1804. Seeing the failure of his colonial efforts, Napoleon decided in 1803 to sell the Louisiana Territory to the United States, instantly doubling the size of the U.S. The selling price in the Louisiana Purchase was less than three cents per acre, a total of $15 million.
In February of what year did the national Convention vote to get rid of slavery?
