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: ESB, Ervia and Airtricity are the three main electricity and gas suppliers in Ireland. There are 19.82 billion cubic metres of proven reserves of gas. Natural gas extraction previously occurred at the Kinsale Head until its exhaustion. The Corrib gas field was due to come on stream in 2013/14. In 2012, the Barryroe field was confirmed to have up to 1.6 billion barrels of oil in reserve, with between 160 and 600 million recoverable. That could provide for Ireland's entire energy needs for up to 13 years, when it is developed in 2015/16. There have been significant efforts to increase the use of renewable and sustainable forms of energy in Ireland, particularly in wind power, with 3,000 MegaWatts of wind farms being constructed, some for the purpose of export. The Sustainable Energy Authority of Ireland  has estimated that 6.5% of Ireland's 2011 energy requirements were produced by renewable sources. The SEAI has also reported an increase in energy efficiency in Ireland with a 28% reduction in carbon emissions per house from 2005 to 2013.
Question: What natural gas site was depleted before the Corrib gas field was due to come on?
Example Output: span

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 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile.
Question: Which year produced more crushed marble, 2005 or 2006?
Example Output: date

Example Input: Passage: Subsequent negotiations led by Jesuit papal legate Antonio Possevino resulted in the 1582 Truce of Jam Zapolski between Russia and the Polish-Lithuanian Commonwealth. This was a humiliation for the Tsar, in part because he requested the truce. Under the agreement Russia would surrender all areas in Livonia it still held and the city of Dorpat to the Polish-Lithuanian Commonwealth, while Polotsk would remain under Commonwealth control. Any captured Swedish territory—specifically Narva—could be retained by the Russians and Velike Luki would be returned from Batory's control to Russia. Possevino made a half-hearted attempt to get John III's wishes taken into consideration, but this was vetoed by the Tsar, probably in collusion with Batory. The armistice, which fell short of a full peace arrangement, was to last ten years and was renewed twice, in 1591 and 1601. Batory failed in his attempts to pressure Sweden into relinquishing its gains in Livonia, particularly Narva. Following a decision by John, the war with Russia ended when the Tsar concluded the Truce of Plussa  with Sweden on 10 August 1583. Russia relinquished most of Ingria but left Narva and Ivangorod under Swedish control. Originally scheduled to last three years, the Russo-Swedish truce was later extended until 1590. During the negotiations, Sweden made vast demands for Russian territory, including Novgorod. Whilst these conditions were probably only for the purposes of negotiation, they may have reflected Swedish aspirations of territory in the region.
Question: When did the Truce of Plussa overlap with the Truce of Jam Zapolski?
