Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992.

[EX Q]: Passage: Since 1444 Si Jifa had repeatedly sent tribute to Ming asking for pardon to no avail. In March 1449, a combined army of 150,000 soldiers was amassed, and the fourth and final campaign to extirpate the Mong Mao threat was launched under the supervision of Wang Ji. The army quickly marched on Mong Yang, which harbored Si Jifa, and captured their strongholds. However Si Jifa managed to escape yet again, and the campaign ended inconclusively with the ruling Shan elite allowed to remain in Mong Yang so long as they never returned to Mong Mao. Sources disagree as to how Si Jifa met his end. One source claims he died in combat in 1449, another says he was captured by the king of Ava and held captive in exchange for Ming territory, and one Shan chronicle claims he reigned for another fifty years. While Mong Mao had been defeated and pacified, Si Jifa's son Si Hongfa continued to rule in Mong Yang and his successors would eventually go on to invade Ava in 1527. So in practice Si Lunfa's family survived as rulers in the neighboring state of Mong Yang under the close observation of Ming. The fourth campaign was also marred by lack of discipline, inefficient administration, and mismanagement of resources. On the first day of mobilization, the entire 150,000 strong army started marching all at once, and many were trampled to death. Food supplies were mismanaged and assigned to individual carriers disproportionate to their weight, and no proper plan for their distribution existed. Some soldiers committed suicide due to the conditions prevalent in the army.
Question: How many years passed from when he was sending Ming tribute to when 150,000 soldiers were amassed?
Answer type: Number
[EX A]: 5.

[EX Q]: Passage: The minimum wage, public-sector wages, and old-age pensions are routinely raised twice a year to ensure that base income is not eroded by inflation. Although no statistics are published on average wages in Uzbekistan, pensions as a proxy for the average wage increased significantly between 1995 and 2006, both in real terms and in U.S. dollars. The monthly old-age pension increased in real (CPI-adjusted) sums by almost a factor of 5 between 1995 and 2006. The monthly pension in U.S. dollars was around $20$25 until 2000, then dropped to $15$20 between 2001 and 2004, and now is $64. The minimum wage was raised to $34.31 in November 2011. Assuming that the average wages in the country are at a level of 3-4 times the monthly pension, we estimate the wages in 2006 at $100$250 per month, or $3$8 per day.
Question: How many years did it take for pensions to increase by a factor of almost 5?
Answer type: Number
[EX A]: 11.

[EX Q]: Passage: Also in August 1689, 1,500 Iroquois, seeking revenge for Governor General Denonville's actions, attacked the French settlement at Lachine. Count Frontenac, who replaced Denonville as governor general, later attacked the Iroquois village of Onondaga. New France and its Indian allies then attacked English frontier settlements in early 1690, most notably at Schenectady in New York. This was followed up by two expeditions. One, on land under Connecticut provincial militia general Fitz-John Winthrop, targeted Montreal; the other, led by Sir William Phips, targeted Quebec. Winthrop's expedition failed due to disease and supply issues, and Phips was defeated in the Battle of Quebec. The Quebec and Port Royal expeditions were the only major New England offensives of King William's War; for the remainder of the war the English colonists were primarily engaged in defensive operations, skirmishes and retaliatory raids. The Iroquois Five Nations suffered from the weakness of their English allies.:290 In 1693 and 1696, the French and their Indian allies ravaged Iroquois towns and destroyed crops while New York colonists remained passive. After the English and French made peace in 1697, the Iroquois, now abandoned by the English colonists, remained at war with New France until 1701,:291 when a peace was agreed at Montreal between New France and a large number of Iroquois and other tribes.
Question: How many years had the Iroquois been fighting with the French?
