Problem: China also began suffering from mounting overpopulation during this period. Population growth was stagnant for the first half of the 17th century due to civil wars and epidemics, but prosperity and internal stability gradually reversed this trend. The introduction of new crops from the Americas such as the potato and peanut allowed an improved food supply as well, so that the total population of China during the 18th century ballooned from 100 million to 300 million people. Soon all available farmland was used up, forcing peasants to work ever-smaller and more intensely worked plots. The Qianlong Emperor once bemoaned the country's situation by remarking "The population continues to grow, but the land does not." The only remaining part of the empire that had arable farmland was Manchuria, where the provinces of Jilin and Heilongjiang had been walled off as a Manchu homeland. The emperor decreed for the first time that Han Chinese civilians were forbidden to settle. Mongols were forbidden by the Qing from crossing the borders of their banners, even into other Mongol Banners and from crossing into neidi (the Han Chinese 18 provinces) and were given serious punishments if they did in order to keep the Mongols divided against each other to benefit the Qing.
What led to overpopulation in China?
The answer is the following: prosperity and internal stability

Problem: The basis for classical economics forms Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. Smith criticized mercantilism, advocating a system of free trade with division of labour. He postulated an "invisible hand" that regulated economic systems made up of actors guided only by self-interest. Karl Marx developed an alternative economic theory, called Marxian economics. Marxian economics is based on the labor theory of value and assumes the value of good to be based on the amount of labor required to produce it. Under this assumption, capitalism was based on employers not paying the full value of workers labor to create profit. The Austrian school responded to Marxian economics by viewing entrepreneurship as driving force of economic development. This replaced the labor theory of value by a system of supply and demand.
What idea did Adam Smith disagree with?
The answer is the following: mercantilism

Problem: In response to the 2007 United States Air Force nuclear weapons incident, Secretary of Defense Robert Gates accepted in June 2009 the resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley. Moseley's successor, General Norton A. Schwartz, a former tactical airlift and special operations pilot was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps.
What US Secretary of the Air Force resigned following a nuclear weapons problem ?
The answer is the following: Michael Wynne

Problem: The first "free election" (Polish: "wolna elekcja") of a king took place in 1492. (To be sure, some earlier Polish kings had been elected with help from bodies such as that which put Casimir II on the throne, thereby setting a precedent for free elections.) Only senators voted in the 1492 free election, which was won by John I Albert. For the duration of the Jagiellonian Dynasty, only members of that royal family were considered for election; later, there would be no restrictions on the choice of candidates.
Who only voted in the election of 1492?
The answer is the following:
senators
