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.

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: In 1984 and 1986, he defeated Nick Begichs wife, Pegge Begich, by 113,582 votes (55.02%) to 86,052 (41.68%) and by 101,799 votes (56.47%) to 74,053 (41.08%), respectively. He defeated Peter Gruenstein with 62.5% of the vote in 1988 and then faced John Devens, the Mayor of Valdez, Alaska, in 1990 and 1992. Young defeated him by 99,003 votes (51.66%) to 91,677 (47.84%) in 1990 and then faced a serious challenge in 1992. He was challenged in the Republican primary by State Senator Virginia M. Collins and defeated her by 24,869 votes (52.98%) to 19,774 (42.12%). In the general election, he was re-elected against Devens by 111,849 votes (46.78%) to 102,378 (42.82%). This is both the lowest winning percentage of his career and the only time he has won without a majority of the vote.
Question: Which year did both parties have less votes than the previous time they had ran, 1984 or 1986?

Answer: date

Question: Passage: In 1659, the war was characterized by Swedish forces defending their strongholds on the southern Baltic coast against allied assaults. A combined force of 17,000 Austrians and 13,000 Brandenburgers led by general Jean-Louis Raduit de Souches invaded Swedish Pomerania, took and burned Greifenhagen, took Wollin island and Damm, besieged Stettin and Greifswald without success, but took Demmin on 9 November. Counterattacks were mounted by general Muller von der Luhnen, who lifted the siege laid on Greifswald by the Brandenburgian prince elector, and major general Paul Wirtz, who from besieged Stettin managed to capture the Brandenburgian ammunition depot at Curau and took it to Stralsund. The Brandenburgians withdrew ravaging the countryside while retreating. In the occupied and annexed Danish provinces, guerilla movements pressed Swedish garrisons. After an uprising, Norwegians took Trondheim in late 1658. In Scania and Zealand, the "snaphaner" led by Lorenz Tuxen and Svend Poulsen ambushed Swedish forces. The Swedish garrison of Bornholm was forced to surrender to Danish insurgents, with the commander killed. In Royal Prussia , Thorn had fallen already in December 1658, but Elbing and Marienwerder withstood. On 24 November, Sweden had to abandon Funen and Langeland after the defeat in the Battle of Nyborg. In January 1660, Sweden lost the Livonian fortress Mitau. Meanwhile, conflicts arose within the anti-Swedish alliance between Habsburg and Poland-Lithuania when Habsburg demanded ever more contributions while not showing the war efforts Poland-Lithuania had expected. With the Russo-Polish War ongoing, most Polish-Lithuanian forces were bound in Ukraine. England, France and the Dutch Republic had agreed on a petition in the First Concert of the Hague, urging Sweden to settle for peace with Denmark on the terms of Roskilde, and peace talks mediated by France were taking place throughout 1659.
Question: Which city was taken, Elbing, Marienwerder, or Thorn?

Answer:
span
