Although the city lost the status of state capital to Columbia in 1786, Charleston became even more prosperous in the plantation-dominated economy of the post-Revolutionary years. The invention of the cotton gin in 1793 revolutionized the processing of this crop, making short-staple cotton profitable. It was more easily grown in the upland areas, and cotton quickly became South Carolina's major export commodity. The Piedmont region was developed into cotton plantations, to which the sea islands and Lowcountry were already devoted. Slaves were also the primary labor force within the city, working as domestics, artisans, market workers, and laborers.
In what year was the cotton gin invented?
A: 1793

Chivalry and the ethos of courtly love developed in royal and noble courts. This culture was expressed in the vernacular languages rather than Latin, and comprised poems, stories, legends, and popular songs spread by troubadours, or wandering minstrels. Often the stories were written down in the chansons de geste, or "songs of great deeds", such as The Song of Roland or The Song of Hildebrand. Secular and religious histories were also produced. Geoffrey of Monmouth (d. c. 1155) composed his Historia Regum Britanniae, a collection of stories and legends about Arthur. Other works were more clearly history, such as Otto von Freising's (d. 1158) Gesta Friderici Imperatoris detailing the deeds of Emperor Frederick Barbarossa, or William of Malmesbury's (d. c. 1143) Gesta Regum on the kings of England.
Who wrote Historia Regum Britanniae?
A: Geoffrey of Monmouth

In some countries, the personal copying exemption explicitly requires that the content being copied was obtained legitimately – i.e., from authorized sources, not file-sharing networks. Other countries, such as the Netherlands, make no such distinction; the exemption there had been assumed, even by the government, to apply to any such copying, even from file-sharing networks. However, in April 2014, the Court of Justice of the European Union ruled that "national legislation which makes no distinction between private copies made from lawful sources and those made from counterfeited or pirated sources cannot be tolerated." Thus, in the Netherlands, for example, downloading from file-sharing networks is no longer legal.
What does the personal copying exemption explicitly need?
A:
was obtained legitimately
