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.

Example Input: Passage: According to the United States Geological Survey, U.S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production (for aggregate and industrial uses) in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate. U.S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for (finished) Marble Index has shown a growth of 12% annually for the 20002006 period, compared to 10.5% annually for the 20002005 period. The largest dimension marble application is tile.
Question: Which year produced more crushed marble, 2005 or 2006?
Example Output: date

Example Input: Passage: As of the census of 2000, there were 6,299 people, 2,519 households, and 1,592 families residing in the city. The population density was 914.5 persons per square mile (353.0/km). There were 2,702 housing units at an average density of 392.3 per square mile (151.4/km). The racial makeup of the city was 75.33% White (U.S. Census), 22.38% African American (U.S. Census) or Race (United States Census), 0.24% Native American (U.S. Census), 0.57% Asian (U.S. Census), 0.08% Pacific Islander (U.S. Census), 0.24% from Race (United States Census), and 1.16% from two or more races. Hispanic (U.S. Census) or Latino (U.S. Census) of any race were 0.89% of the population.
Question: Which racial group made up the smallest percentage of the population?
Example Output: span

Example Input: Passage: As of February 1, 2008, the U.S. Board on Geographic Names had identified 5,564 natural streams in the State of Colorado. Of this number, 147 larger streams (2.6%) were named river and 11 (0.2%) were named rio. The vast majority of the Colorado streams (5082 or 91.3%) were named stream. Of the remaining Colorado streams, 122 (2.2%) were named arroyo (creek), 60 (1.1%) were named wash (creek), 44 (0.8%) were named stream, 18 (0.3%) were named stream, 17 (0.3%) were named stream, 17 (0.3%) were named stream, 15 (0.3%) were named stream, 10 (0.2%) were named River delta, but not a single stream was named stream. Perhaps the strangest stream name in Colorado belongs to the West Fork East Fork Williams Fork located in Garfield County, Colorado.
Question: How many more natural streams were named arroyo compared to rio and wash combined?
Example Output:
number
