Input: Crimean War
Minor naval skirmishes also occurred in the Far East, where at Petropavlovsk on the Kamchatka Peninsula a British and French Allied squadron including HMS Pique under Rear Admiral David Price and a French force under Counter-Admiral Auguste Febvrier Despointes besieged a smaller Russian force under Rear Admiral Yevfimy Putyatin. In September 1854, an Allied landing force was beaten back with heavy casualties, and the Allies withdrew. The Russians escaped under the cover of snow in early 1855 after Allied reinforcements arrived in the region.

Input: Protestantism
In the Middle Ages, the Church and the worldly authorities were closely related. Martin Luther separated the religious and the worldly realms in principle (doctrine of the two kingdoms). The believers were obliged to use reason to govern the worldly sphere in an orderly and peaceful way. Luther's doctrine of the priesthood of all believers upgraded the role of laymen in the church considerably. The members of a congregation had the right to elect a minister and, if necessary, to vote for his dismissal (Treatise On the right and authority of a Christian assembly or congregation to judge all doctrines and to call, install and dismiss teachers, as testified in Scripture; 1523). Calvin strengthened this basically democratic approach by including elected laymen (church elders, presbyters) in his representative church government. The Huguenots added regional synods and a national synod, whose members were elected by the congregations, to Calvin's system of church self-government. This system was taken over by the other reformed churches.

Who added synods to church government?
Output: The Huguenots

Input: Swaziland
About 75% of the population is employed in subsistence agriculture upon Swazi Nation Land (SNL). In contrast with the commercial farms, Swazi Nation Land suffers from low productivity and investment. This dual nature of the Swazi economy, with high productivity in textile manufacturing and in the industrialised agricultural TDLs on the one hand, and declining productivity subsistence agriculture (on SNL) on the other, may well explain the country's overall low growth, high inequality and unemployment.

What are the problems with Swazi Nation Land?
Output: low productivity and investment

Input: Gregorian calendar
During the period between 1582, when the first countries adopted the Gregorian calendar, and 1923, when the last European country adopted it, it was often necessary to indicate the date of some event in both the Julian calendar and in the Gregorian calendar, for example, "10/21 February 1750/51", where the dual year accounts for some countries already beginning their numbered year on 1 January while others were still using some other date. Even before 1582, the year sometimes had to be double dated because of the different beginnings of the year in various countries. Woolley, writing in his biography of John Dee (1527–1608/9), notes that immediately after 1582 English letter writers "customarily" used "two dates" on their letters, one OS and one NS.

What difference in dating caused the use of double-dating documents?
Output:
different beginnings of the year
