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: The 1970s marked a time of economic uncertainty and troubled relations between the U.S. and certain Middle-Eastern countries. To begin with, the decade started off with the ongoing Recession of 1969–70. Following that, the 1970s energy crisis ensued which included the 1973–75 recession, the 1973 oil crisis as well as the 1979 energy crisis beginning as a prelude to a disastrous economic climate injected with stagflation; the combination between high unemployment and high inflation. However, on November 14, 1972, the average closed above the 1,000 mark (1,003.16) for the first time, during a brief relief rally in the midst of a lengthy bear market. Between January 1973 and December 1974, the average lost 48% of its value in what became known as the 1973–1974 stock market crash; with the situation being exacerbated by the events surrounding the Yom Kippur War. The index closed at 577.60, on December 4, 1974. During 1976, the index went above 1000 several times, and it closed the year at 1,004.75. Although the Vietnam War ended in 1975, new tensions arose towards Iran surrounding the Iranian Revolution in 1979. Other notable disturbances such as the Lebanese Civil War, the Ethiopian Civil War, the Indo-Pakistani War of 1971 and the Angolan Civil War which the U.S. and Soviet Union considered critical to the global balance of power, seemed to have had little influence towards the financial markets. Performance-wise for the decade, gains remained virtually flat, rising less than 5% from about the 800 level to 838.
Question: How many points higher did the index close in 1976 compared to December 4, 1974?

Answer: number


Question: Passage: The Bethencourt era ended in 1418 when Maciot sold his holdings and the rights to subjugate the remaining islands to Enrique Pérez de Guzmán. From this point on the intervention of the King of Castile increased. Between 1418 and 1445 dominion over the islands changed hands on a number of occasions. Finally, control over the conquered islands and the right to further conquests fell to Hernán Peraza The Elder and his children Guillén Peraza and Inés Peraza. The death of Guillén Peraza in the attack on La Palma has been immortalized in a moving lament. After the death of her brother Inés and her husband Diego García de Herrera became the sole rulers of the islands until 1477 when they ceded La Gomera to their son Hernán Peraza The Younger and the rights to the conquest of La Palma, Gran Canaria and Tenerife to the King of Castile. The island of La Gomera was not taken in battle but was incorporated into the Peraza-Herrera fiefdom through an agreement between Hernán Peraza The Elder and some of the insular aboriginal groups who accepted the rule of the Castilian. However, there were a number of uprisings by the guanches due to outrages committed by the rulers on the native Gomeros. The last one, in 1488 caused the death of the islands ruler, Hernán Peraza, whose widow, Beatriz de Bobadilla y Ossorio, had to seek the assistance of Pedro de Vera, conqueror of Gran Canaria, in order to snuff out the rebellion. The subsequent repression caused the death of two hundred rebels and many others were sold into slavery in the Spanish markets.
Question: What year did the rebellion end?

Answer: date


Question: 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: What was the date the Congress of Vienna signed their "final act?

Answer:
date
