Input: Read this: Most of Bermuda's black population trace some of their ancestry to Native Americans, although awareness of this is largely limited to St David's Islanders and most who have such ancestry are unaware of it. During the colonial period, hundreds of Native Americans were shipped to Bermuda. The best-known examples were the Algonquian peoples who were exiled from the southern New England colonies and sold into slavery in the 17th century, notably in the aftermaths of the Pequot and King Philip's wars.
Question: During what period were hundreds of St David's Islanders shipped to Bermuda?

Output: unanswerable

Input: Read this: The term can be found used in an October 1845 Massachusetts Circuit Court ruling in the patent case Davoll et al. v. Brown., in which Justice Charles L. Woodbury wrote that "only in this way can we protect intellectual property, the labors of the mind, productions and interests are as much a man's own...as the wheat he cultivates, or the flocks he rears." The statement that "discoveries are...property" goes back earlier. Section 1 of the French law of 1791 stated, "All new discoveries are the property of the author; to assure the inventor the property and temporary enjoyment of his discovery, there shall be delivered to him a patent for five, ten or fifteen years." In Europe, French author A. Nion mentioned propriete intellectuelle in his Droits civils des auteurs, artistes et inventeurs, published in 1846.
Question: When did French author A. Nion mention intellectual property?

Output: 1846

Input: Read this: Play stops when the ball carrier's knee, elbow, or any other body part aside from the feet and hands, is forced to the ground (a tackle); when a forward pass is not caught on the fly (during a scrimmage); when a touchdown (see below) or a field goal is scored; when the ball leaves the playing area by any means (being carried, thrown, or fumbled out of bounds); or when the ball carrier is in a standing position but can no longer move forwards (called forward progress). If no score has been made, the next play starts from scrimmage.
Question: What parts of the ball carriers forward progress won't stop play when touching the ground?

Output: unanswerable

Input: Read this: 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.
Question: What led to overpopulation in China?

Output:
prosperity and internal stability
