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:

Passage: Hoping to snap a two-game losing skid, the Steelers went home, donned their throwback uniforms, and prepared for a Week 4 Sunday night duel with the San Diego Chargers. Pittsburgh got off to a fast start in the opening half with running back Rashard Mendenhall (filling in for the injured Willie Parker) helping out the cause on a 1-yard touchdown run in the first quarter, followed by quarterback Ben Roethlisberger's 19-yard touchdown pass to running back Mewelde Moore.  The Steelers would carry their fast start into the second quarter as Mendenhall got a 2-yard touchdown run. In the third quarter, Pittsburgh picked up where they left off with Roethlisberger completing a 6-yard touchdown pass to tight end Heath Miller.  The Chargers would get on the board with quarterback Philip Rivers' 3-yard touchdown pass to tight end Antonio Gates.  In the fourth quarter, San Diego began to play catch-up with a special teams play. Fullback Jacob Hester would strip return specialist Stefan Logan of the ball and go 41&#160;yards for a touchdown. The Steelers came right back with a trick play, as Moore completed a 6-yard touchdown pass to Miller. However, the Chargers would slash away at the Steelers' lead with Rivers completing a 30-yard touchdown pass to Gates and a 13-yard touchdown pass to wide receiver Chris Chambers. Pittsburgh would answer the call with kicker Jeff Reed booting a 46-yard field goal, followed by linebacker James Harrison causing a sack and a fumble. It would allow linebacker James Farrior to recover the fumble and secure the victory. With the win, not only did the Steelers improve to 2-2, but they also extended their regular season home-game winning streak over San Diego to 13-straight. Mendenhall would have a career night with 29 carries for 165&#160;yards, in addition to his two rushing touchdowns.
Question: Which was the first quarter that the Chargers scored any points?

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.
