Q: Question: How many years had the American Revolution been ongoing when the British evacuated Boston? Passage:Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.

Q: Question: Was Nathan Sivin alive when Han Zhenhua claimed that Nanhai referred to the Scarborough Shoal? Passage:The People's Republic of China and the Republic of China (Taiwan) claim that Chinese people discovered the shoal centuries ago and that there is a long history of Chinese fishing activity in the area. The shoal lies within the nine-dotted line drawn by China on maps marking its claim to islands and relevant waters consistent with United Nations Convention on the Law of the Sea (UNCLOS) within the South China Sea. An article published in May 2012 in the PLA Daily" states that Chinese astronomer Guo Shoujing went to the island in 1279, under the Yuan dynasty, as part of an empire-wide survey called "Measurement of the Four Seas" (四海测验), however, no such 13th century map has been made public by China nor such evidence on the existence of the map is known. In 1979 historical geographer Han Zhenhua (韩振华) was among the first scholars to claim that the point called "Nanhai" (literally, "South Sea") in that astronomical survey referred to Scarborough Shoal. In 1980 during a conflict with Vietnam for sovereignty over the Paracel Islands (Xisha Islands), however, the Chinese government issued an official document claiming that "Nanhai" in the 1279 survey was located in the Paracels. Historical geographer Niu Zhongxun defended this view in several articles. In 1990, a historian called Zeng Zhaoxuan (曾昭璇) argued instead that the Nanhai measuring point was located in Central Vietnam. Historian of astronomy Chen Meidong (陈美东) and historian of Chinese science Nathan Sivin have since agreed with Zeng's position in their respective books about Guo Shoujing.

Q: Question: Which of the Nintendo 64 (N64) predecessors to Banjo-Kazooie: Grunty's Revenge sold the most units?  Passage:Like its Nintendo 64 (N64) predecessors Banjo-Kazooie (1998) and Banjo-Tooie (2000), Banjo-Kazooie: Grunty's Revenge is an adventure platformer with a strong emphasis on collecting items. The player must control the player characters, the bear Banjo and his bird friend Kazooie, through several levels. The story takes place between the events of the N64 Banjo games and employs time travel as a key plot device. In the story, the evil witch and antagonist of the previous games, Gruntilda, transfers her spirit into a mechanical body before kidnapping Kazooie and going back in time to prevent her from meeting Banjo, thus preventing the events of Banjo-Kazooie. The shaman Mumbo Jumbo sends Banjo back in time to stop Gruntilda. At the start of the game, the player controls just Banjo, who can walk, jump, crouch, and attack enemies with his backpack. Collecting golden musical notes scattered around levels will enable Banjo to purchase three additional abilities from a mole named Bozzeye. Eventually, Banjo rescues Kazooie, who rides in his backpack for the remainder of the game. With Kazooie, the player can purchase seven new abilities, such as temporary flight. While Grunty's Revenges game mechanics are largely the same as those from the N64 games, it is presented in 2D from an overhead perspective with pre-rendered graphics, rather than the 3D presentation of its predecessors.
