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: In the county, the population was spread out with 26.20% under the age of 18, 9.30% from 18 to 24, 26.50% from 25 to 44, 23.50% from 45 to 64, and 14.60% who were 65 years of age or older. The median age was 37 years. For every 100 females there were 95.90 males. For every 100 females age 18 and over, there were 92.50 males.
Question: Were there more people between 25 to 44 or 45 and older?

Output: span

Input: Consider Input: Passage: Coming off of their dominant home win over the Steelers, the Ravens flew to Paul Brown Stadium for an AFC North rematch with the Cincinnati Bengals, trying to win the division and a playoff berth on this Thursday Night fight. After a scoreless first quarter, the Ravens trailed early as Bengals kicker Shayne Graham kicked a 23-yard and a 27-yard field goal. In the third quarter, things went from bad to worse for Baltimore as QB Carson Palmer completed a 40-yard flea-flicker TD pass to WR T. J. Houshmandzadeh for the only score of the period. In the fourth quarter, the Ravens valiantly tried to fight back, as QB Steve McNair completed a 36-yard TD pass to WR Derrick Mason. However, a failed onside kick spelled Baltimore's doom. With the loss, the Ravens fell to 9-3.
Question: How many wins did the Ravens have after this game?

Output: number

Input: Consider Input: Passage: The exact origin of the 260-day count is not known, but there are several theories. One theory is that the calendar came from mathematical operations based on the numbers thirteen and twenty, which were important numbers to the Maya. The numbers multiplied together equal 260. Another theory is that the 260-day period came from the length of human pregnancy. This is close to the average number of days between the first missed menstrual period and birth, unlike Naegele's rule which is 40 weeks between the last menstrual period and birth. It is postulated that midwives originally developed the calendar to predict babies' expected birth dates. A third theory comes from understanding of astronomy, geography and paleontology. The mesoamerican calendar probably originated with the Olmecs, and a settlement existed at Izapa, in southeast Chiapas Mexico, before 1200 BCE. There, at a latitude of about 15 N, the Sun passes through zenith twice a year, and there are 260 days between zenithal passages, and gnomons , were found at this and other sites. The sacred almanac may well have been set in motion on August 13, 1359 BCE, in Izapa.
