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.

Input: Consider Input: Passage: The immediate background was Napoleonic France's defeat and surrender in May 1814, which brought an end to 25 years of nearly continuous war. Negotiations continued despite the outbreak of fighting triggered by Napoleon's dramatic return from exile and resumption of power in France during the Hundred Days of March to July 1815. The Congress's "final act" was signed nine days before his final defeat at Waterloo on 18 June 1815. The Congress has often been criticized for causing the subsequent suppression of the emerging national and liberal movements, and it has been seen as a reactionary movement for the benefit of traditional monarchs. However, others praise it for having created relatively long-term stability and peaceful conditions in most of Europe. In a technical sense, the "Congress of Vienna" was not properly a congress: it never met in plenary session, and most of the discussions occurred in informal, face-to-face sessions among the Great Powers of Austria, Britain, France, Russia, and sometimes Prussia, with limited or no participation by other delegates. On the other hand, the congress was the first occasion in history where, on a continental scale, national representatives came together to formulate treaties instead of relying mostly on messages among the several capitals. The Congress of Vienna settlement, despite later changes, formed the framework for European international politics until the outbreak of the First World War in 1914.
Question: On what date was the Congress's "final act" signed?

Output: date


Input: Consider Input: Passage: This drop was caused by a combination of sharply lower petroleum prices in world markets and voluntary production cuts in Brunei. The GDP recovered somewhat since 1986, growing by 12% in 1987, 1% in 1988, and 9% in 1989. In recent years, GDP growth was 3.5% in 1996, 4.0% in 1997, 1.0% in 1998, and an estimated 2.5% in 1999. However, the 1999 GDP was still only about $4.5 billion, well below the 1980 peak.
Question: Did the GDP grow by more in 1987 or 1988?

Output: date


Input: Consider Input: Passage: In 1749, the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country. The grant required that it settle 100 families in the territory and construct a fort for their protection. But the territory was also claimed by Pennsylvania, and both colonies began pushing for action to improve their respective claims. In 1750, Christopher Gist explored the Ohio territory, acting on behalf of both Virginia and the company, and he opened negotiations with the Indian tribes at Logstown. He completed the 1752 Treaty of Logstown in which the local Indians agreed to terms through their "Half-King" Tanacharison and an Iroquois representative. These terms included permission to build a strong house at the mouth of the Monongahela River on the modern site of Pittsburgh, Pennsylvania. By the late 17th century, the Iroquois had pushed many tribes out of the Ohio Valley, and they laid claim to it as their hunting ground by right of conquest. The War of the Austrian Succession  formally ended in 1748 with the signing of the Treaty of Aix-la-Chapelle, which was primarily focused on resolving issues in Europe. The issues of conflicting territorial claims between British and French colonies were turned over to a commission, but it reached no decision. Frontier areas were claimed by both sides, from Nova Scotia and Acadia in the north to the Ohio Country in the south. The disputes also extended into the Atlantic Ocean, where both powers wanted access to the rich fisheries of the Grand Banks off Newfoundland.
Question: What happened first: Treaty of Logstown or Treaty of Aix-la-Chapelle?


Output: span
