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: From 1975, Flavin installed permanent works in Europe and the United States, including "Untitled. In memory of Urs Graf" at the Kunstmuseum Basel (conceived 1972, realized 1975); the Kröller-Müller Museum, Otterlo, Netherlands (1977); Hudson River Museum, Yonkers, New York (1979); United States Courthouse, Anchorage, Alaska (1979-89); the Staatliche Kunsthalle Baden-Baden, Germany (1989); the lobby of the MetroTech Center (with Skidmore, Owings & Merrill), Brooklyn, New York (1992); seven lampposts outside the Städtische Galerie im Lenbachhaus, Munich (1994); Hypovereinsbank, Munich (1995); Institut Arbeit und Technik/Wissenschaftspark, Gelsenkirchen, Germany (1996); and the Union Bank of Switzerland, Bern (1996).  Additional sites for Flavins architectural “interventions” became the Grand Central Station in New York (1976), Hamburger Bahnhof in Berlin (1996), and the Chinati Foundation in Marfa, Texas (2000). His large-scale work in colored fluorescent light for six buildings at the Chinati Foundation was initiated in the early 1980s, although the final plans were not completed until 1996. His last artwork was a site-specific art at Santa Maria Annunciata in Chiesa Rossa, Milan, Italy. The 1930s church was designed by Giovanni Muzio. The design for the piece was completed two days before Flavins death on November 29, 1996. Its installation was completed one year later with the assistance of the Dia Art Foundation and Fondazione Prada.
Question: In what year was the site-specific art at Santa Maria Annunciata in Chiesa Rossa, Milan, Italy completed?
Example Output: date

Example Input: Passage: In the city, the year 2010 population was spread out with 26.3% under the age of 18, 13.6% from 18 to 24, 30.7% from 25 to 44, 21.1% from 45 to 64, and 7.2% who were 65 years of age or older. The median age was 32 years. For every 100 females, there were 92.5 males. For every 100 females age 18 and over, there were 88.4 males.
Question: Which age group is larger: under the age of 18 or 65 years of age or older?
Example Output: span

Example Input: Passage: The war had three phases. Initially it was a localized feud between supporters of Gebhard and those of the Catholic core of the Cathedral Chapter. With the election of Ernst of Bavaria as a competing archbishop, what had been a local conflict expanded in scale: Ernst's election guaranteed the military, diplomatic, and financial interest of the Wittelsbach family in the Electorate of Cologne's local affairs. After the deaths of Louis VI, Elector Palatine in 1583 and William the Silent in 1584, the conflict shifted gears again, as the two evenly matched combatants sought outside assistance to break the stalemate. Finally, the intervention of Alexander Farnese, Duke of Parma, who had at his command the Spanish Army of Flanders, threw the balance of power in favor of the Catholic side. By 1588, Spanish forces had pushed Gebhard from the Electorate. In 1588 he took refuge in Strassburg, and the remaining Protestant strongholds of the Electorate fell to Parma's forces in 1589.
Question: When did the conflict end?
