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.

Q: Passage: In 1984 and 1986, he defeated Nick Begichs wife, Pegge Begich, by 113,582 votes (55.02%) to 86,052 (41.68%) and by 101,799 votes (56.47%) to 74,053 (41.08%), respectively. He defeated Peter Gruenstein with 62.5% of the vote in 1988 and then faced John Devens, the Mayor of Valdez, Alaska, in 1990 and 1992. Young defeated him by 99,003 votes (51.66%) to 91,677 (47.84%) in 1990 and then faced a serious challenge in 1992. He was challenged in the Republican primary by State Senator Virginia M. Collins and defeated her by 24,869 votes (52.98%) to 19,774 (42.12%). In the general election, he was re-elected against Devens by 111,849 votes (46.78%) to 102,378 (42.82%). This is both the lowest winning percentage of his career and the only time he has won without a majority of the vote.

Q: Passage: The screening suggests that in 2000, 19 percent of all newborn babies in Metropolitan France had at least one parent originating from one of the risk regions. The figure for 2007 was 28.45 percent, for 2010 31.5 percent, for 2012 34.44 percent, for 2013 35.7 percent, and for 2015 38.9 percent. These percentages vary widely among French regions; for example, in 2015, screening suggested that only 8.1% of children born in Brittany had a parent originating from a sickle-cell risk region, while 73.4% of children born in Ile-de-France (which includes Paris) did. The percentage for Ile-de-France was a significant increase from 54.2% in 2005. However, a 2014 story in Le Monde suggested that the testing figures for Ile-de-France were distorted by the practices of some hospitals in the region, which choose to test all babies whether or not they have parents with ancestry from an endemic sickle-cell region.

Q: Passage: Since the later 20th century, the Seneca have been increasingly active in exercising sovereignty on their reservation and enforcing their property rights. Their relations with the non-Native surrounding population have become contentious, in regard to excise tax advantages and to their property rights. In the 1990s, the Senecas won a prolonged court battle to assume ownership of all land on their reservation, including that owned by private non-Seneca. The city had been developed under a 99-year federal lease arrangement with the Seneca Nation. It had provided land to railroads to encourage development, which the railroad developed for workers and their families, and related businesses. This arrangement was confirmed by acts of Congress in 1875, 1890 and 1990. When that lease expired in 1991, the Seneca Nation demanded that the previous owners sign new leases with their nation for not only the underlying land, but also the improvements as well, or be evicted. The Seneca evicted fifteen property owners from their homes for refusing to sign over their properties. The increase in lease revenue from this reinterpretation has generated sufficient revenue for the nation to pay its enrolled members a quarterly social dividend, providing those members with a basic income. In a similar case in 2012, the Seneca ordered an eviction of 80 residents of summer cottages at Snyder Beach on the Cattaraugus Reservation, a location near Sunset Bay. They had previously notified the owner of the land that his leases to non-Seneca were not permissible, but he had done nothing to clear his property. Some of the residents were from families who had rented there for decades. The Seneca described the non-Natives as constituting a long-standing "illegal occupation".
