This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Example Input: Passage: The Hotak dynasty  was an Afghan monarchy of the Ghilji Pashtuns, established in April 1709 by Mirwais Hotak after leading a successful revolution against their declining Persian Safavid overlords in the region of Loy Kandahar  in what is now southern Afghanistan. It lasted until 1738 when the founder of the Afsharid dynasty, Nader Shah Afshar, defeated Hussain Hotak during the long siege of Kandahar, and started the reestablishment of Iranian suzerainty over all regions lost decades before against the Iranian archrival, the Ottoman Empire, and the Russian Empire. At its peak, the Hotak dynasty ruled briefly over an area which is now Afghanistan, Iran, western Pakistan, and some parts of Tajikistan and Turkmenistan. In 1715, Mirwais died of a natural cause and his brother Abdul Aziz succeeded the monarchy. He was quickly followed by Mahmud who ruled the empire at its largest extent for a mere three years. Following the 1729 Battle of Damghan, where Ashraf Hotak was roundly defeated by Nader Shah, Ashraf was banished to what is now southern Afghanistan with Hotak rule being confined to it. Hussain Hotak became the last ruler until he was also defeated in 1738.
Question: When did the first event happen?
Example Output: date

Example Input: Passage: Through the 1990s and into the 2000s, the city diversified its economy; manufacturing now employs 16.9 percent of Allen Countys workforce. Other sectors include distribution, transportation, and logistics (23.1 percent), health care (17.9 percent), professional and business services (12.1 percent), leisure and hospitality (11.1 percent), and financial services (6.3 percent). The leisure and hospitality sector has especially grown, with 5.8 million visitors spending $545 million in 2013, a 4.3 percent increase over the previous year. The city is a center for the defense industry, employing thousands at such companies as BAE Systems Inc. (1,150), Harris Corporation (888), Raytheon Systems (950), and the Fort Wayne Air National Guard Station (423).
Question: Who employs the fewest people in the defense industry?
Example Output: span

Example Input: 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?
