Problem: In November 1795, there was a debate in Parliament on the high price of corn and Burke wrote a memorandum to Pitt on the subject. In December Samuel Whitbread MP introduced a bill giving magistrates the power to fix minimum wages and Fox said he would vote for it. This debate probably led Burke to editing his memorandum, as there appeared a notice that Burke would soon publish a letter on the subject to the Secretary of the Board of Agriculture, Arthur Young; but he failed to complete it. These fragments were inserted into the memorandum after his death and published posthumously in 1800 as, Thoughts and Details on Scarcity. In it, Burke expounded "some of the doctrines of political economists bearing upon agriculture as a trade". Burke criticised policies such as maximum prices and state regulation of wages, and set out what the limits of government should be:

Problem: According to Joshua Baron a "researcher, lecturer, and consultant on international conflict" since the early 1960s direct military conflicts and major confrontations have "receded into the background" with regards to relations among the great powers. Baron argues several reasons why this is the case, citing the unprecedented rise of the United States and its predominant position as the key reason. Baron highlights that since World War Two no other great power has been able to achieve parity or near parity with the United States, with the exception of the Soviet Union for a brief time. This position is unique among the great powers since the start of the modern era (the 16th century), where there has traditionally always been "tremendous parity among the great powers". This unique period of American primacy has been an important factor in maintaining a condition of peace between the great powers.
Since what century has there always been parity in powers?

Answer: modern era (the 16th century)

Problem: Following the fall of Wu and the turmoil of the Wu Hu uprising against the Jin dynasty (265420), most of elite Chinese families had collaborated with the non-Chinese rulers and military conquerors in the north. Some may have lost social privilege, and took refugee in areas south to Yangtze River. Some of the Chinese refugees from north China might have resided in areas near Hangzhou. For example, the clan of Zhuge Liang (181234), a chancellor of the state of Shu Han from Central Plain in north China during the Three Kingdoms period, gathered together at the suburb of Hangzhou, forming an exclusive, closed village Zhuge Village (Zhege Cun), consisting of villagers all with family name "Zhuge". The village has intentionally isolated itself from the surrounding communities for centuries to this day, and only recently came to be known in public. It suggests that a small number of powerful, elite Chinese refugees from the Central Plain might have taken refugee in south of the Yangtze River. However, considering the mountainous geography and relative lack of agrarian lands in Zhejiang, most of these refugees might have resided in some areas in south China beyond Zhejiang, where fertile agrarian lands and metropolitan resources were available, mainly north Jiangsu, west Fujian, Jiangxi, Hunan, Anhui,and provinces where less cohesive, organized regional governments had been in place. Metropolitan areas of Sichuan was another hub for refugees, given that the state of Shu had long been founded and ruled by political and military elites from the Central Plain and north China. Some refugees from the north China might have found residence in south China depending on their social status and military power in the north. The rump Jin state or the Southern Dynasties vied against some elite Chinese from the Central Plain and south of the Yangtze River.
