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: Antananarivo has been the largest city on the island since at least the late 18th century, when its population was estimated at 15,000. By 1810, the population had grown to 80,000 before declining dramatically between 1829 and 1842 during the reigns of Radama I and especially Ranavalona I. Because of a combination of war, forced labor, disease and harsh measures of justice, the population of Imerina fell from 750,000 to 130,000 during this period. In the final years of the Kingdom of Imerina, the population had recovered to between 50,000 and 75,000; most of the population were slaves who were largely captured in provincial military campaigns. In 1950, Antananarivos population was around 175,000. By the late 1990s the population of the metropolitan area had reached 1.4 million, and – while the city itself now has a population (2013) of about 1,300,000 – with suburbs lying outside the city limits it had grown to almost 2.1 million in 2013. The metropolitan area is thus home to 10 percent of the islands residents. Rural migration to the capital propels this growth; the citys population exceeds that of the other five provincial capitals combined.
Question: How many percent of the island's population lives outside the metropolitan area of Antananarivo?

Answer: number


Question: Passage: After a tough win over the Ravens, the Bengals returned home for a game against the Chiefs.  They would score first in the first quarter when Jeremy Hill ran for an 8-yard TD for a 7-0 lead.  Cairo Santos then put a 22-yard field goal through to give the Chiefs their first score of the game 7-3.  The Bengals moved ahead by 11 when Giovani Bernard ran for a 13-yard TD for a 14-3 game.In the second quarter, it was all Chiefs as Santos nailed 3 straight field goals eventually to get within 2 points before halftime:  from 40, 51, and 34 yards out for 14-6, 14-9, and the 14-12 score at halftime.  The Bengals however got back to work in the third quarter when Andy Dalton found Brandon Tate on a 55-yard TD pass increasing their lead to 21-12.  The Chiefs came within 6 as Santos put a 40-yard field goal through for a 21-15 game.  The Bengals moved ahead by 14 when Hill ran for a 5-yard TD (with a successful 2-point conversion) for a 29-15 game.  In the fourth quarter, the Chiefs moved within 11 as Santos put a 29-yard field goal through for a 29-18 game.  The Bengals would pretty much seal the game when Hill ran for a 1-yard TD for a 36-18 game.  The Chiefs wrapped up the scoring of the game when Santos kicked yet another 51-yard field goal for the eventual final score of 36-21. With the win, the Bengals improved to 4-0, their first such start since 2005. The defense also didn't allow a single touchdown (just 7 field goals). They also won their 5th straight home game against the Chiefs.
Question: How many points did the Bengals win the game by?

Answer: number


Question: Passage: The causes of the Polish-Ottoman War of 1672-76 can be traced to 1666. Petro Doroshenko Hetman of Zaporizhian Host, aiming to gain control of Ukraine but facing defeats from other factions struggling over control of that region, in a final bid to preserve his power in Ukraine, signed a treaty with Sultan Mehmed IV in 1669 that recognized the Cossack Hetmanate as a vassal of the Ottoman Empire.:273 In the meantime, Commonwealth forces were trying to put down unrest in Ukraine, but were weakened by decades long wars ). Trying to capitalize on that weakness, Tatars, who commonly raided across the Commonwealth borders in search of loot and plunder, invaded, this time allying themselves with Cossacks under hetman Doroshenko. They were however stopped by Commonwealth forces under hetman John Sobieski, who stopped their first push , defeating them several times, and finally gaining an armistice after the Battle of Podhajce. In 1670, however, hetman Doroshenko tried once again to take over Ukraine, and in 1671 Khan of Crimea, Adil Giray, supportive of the Commonwealth, was replaced with a new one, Selim I Giray, by the Ottoman sultan. Selim entered into an alliance with the Doroshenko's Cossacks; but again like in 1666-67 the Cossack-Tatar forces were dealt defeats by Sobieski. Selim then renewed his oath of allegiance to the Ottoman Sultan and pleaded for assistance, to which the Sultan agreed. Thus an irregular border conflict escalated into a regular war in 1671, as the Ottoman Empire was now prepared to send its regular units onto the battlefield in a bid to try to gain control of that region for itself.:646
