Question: Passage: As economists Milton Friedman and Anna J. Schwartz have noted, the decade from 1869 to 1879 saw a growth of 3 percent per year in money national product, an outstanding real national product growth of 6.8 percent per year in this period and a rise of 4.5 percent per year in real product per capita. Even the alleged "monetary contraction" never took place, the money supply increasing by 2.7 percent per year in this period. From 1873 through 1878, before another spurt of monetary expansion, the total supply of bank money rose from $1.964 billion to $2.221 billion, a rise of 13.1 percent or 2.6 percent per year. In short, a modest but definite rise, and scarcely a contraction. Although per-capita nominal income declined very gradually from 1873 to 1879, that decline was more than offset by a gradual increase over the course of the next 17 years.
Question: When did the decline that was more than offset by a gradual increase for per-capita nominal income come to a stop?

Answer: date


Question: Passage: Jordan played three seasons for coach Dean Smith at the North Carolina Tar Heels mens basketball. As a freshman, he was a member of the 1981–82 North Carolina Tar Heels mens basketball team in 1982 NCAA Division I Mens Basketball Tournament. Jordan joined the Bulls in 1984–85 NBA season as the 1984 NBA draft draft (sports) pick. He quickly emerged as a league star and entertained crowds with his prolific scoring. His leaping ability, demonstrated by performing slam dunks from the free throw line in Slam Dunk Contests, earned him the nicknames Air Jordan and His Airness. He also gained a reputation for being one of the best defensive players in basketball. In 1991 NBA Finals, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 NBA Finals and 1993 NBA Finals, securing a "three-peat". Although Jordan abruptly retired from basketball before the beginning of the 1993–94 NBA season, and started a new career in Minor League Baseball, he returned to the Bulls in 1994–95 NBA season and led them to three additional championships in 1996 NBA Finals, 1997 NBA Finals, and 1998 NBA Finals, as well as a then-record List of NBA teams by single season win percentage in the 1995–96 NBA season. Jordan retired for a second time in 1998–99 NBA season, but returned for two more NBA seasons from 2001 to 2003 as a member of the Wizards.
Question: What year did Jordan first play for the North Carolina Tar Heels?

Answer: date


Question: Passage: The 1910 Chinese expedition to Tibet or the Chinese invasion of Tibet in 1910 was a military campaign of the Qing dynasty to establish direct rule in Tibet in early 1910. The expedition occupied Lhasa on February 12 and officially deposed the 13th Dalai Lama on the 25th. Qing rule of Tibet was established in the early 18th century after the 1720 Chinese expedition to Tibet, but it was essentially a protectorate rather than a direct rule. The actual rule also waned considerably with the gradual weakening of the Qing dynasty in the 19th century. After the British expedition to Tibet in 1904 and the Sino-British treaty in 1906, the Qing decided to establish direct rule over Tibet and thus sent such an expedition in 1910. As Professor Dawa Norbu stated, "The British military expedition and subsequent convention made the Chinese realize that their power in Tibet had disappeared. So, in 1910 China invaded Tibet, and the Dalai Lama fled to India." In the late winter of 1910, the Manchu government in Beijing was furious with the 13th Dalai Lama. His government, having witnessed the dissolution of its domains in Khams by Qing administrators, and fearing that the amban in Lhasa was going to eliminate its temporal authority, cut this imperial officer off from the sustenance that the Tibet government had guaranteed him in a prior agreement with the Qing court. When a relief column arrived in Lhasa from Sichuan to break the amban out of his isolation, the Dalai Lama fled for British India. However, the direct rule over Tibet proved short-lived: after the outbreak of the Xinhai Revolution and the Xinhai Lhasa turmoil in 1911-1912, Qing rule essentially ended in Lhasa and other parts of Tibet. All Qing forces left Tibet by the end of 1912.
Question: When did the Qing dynasty get control over Tibet?
