A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992.

Passage: Hoping to rebound from their divisional road loss to the Browns, the Ravens flew to Bill Walsh Field at Monster Park for an interconference duel with the San Francisco 49ers. Baltimore would even go up against the QB that helped them win Super Bowl XXXV, Trent Dilfer, because QB Alex Smith was out with a separated shoulder. After a scoreless first quarter, the Ravens got the first punch with kicker Matt Stover getting a 26-yard and a 32-yard field goal. In the third quarter, Stover gave Baltimore a 49-yard field goal. However, the 49ers threatened with Dilfer completing a 23-yard TD pass to WR Arnaz Battle. The 49ers' kicker Joe Nedney missed the potential game-winning field goal from 52 yards out, and the Ravens held on for the lead. 
Question: How many yards was Matt Stover's longest field goal? 
Answer type: Number 
49.

Passage: The minimum wage, public-sector wages, and old-age pensions are routinely raised twice a year to ensure that base income is not eroded by inflation. Although no statistics are published on average wages in Uzbekistan, pensions as a proxy for the average wage increased significantly between 1995 and 2006, both in real terms and in U.S. dollars. The monthly old-age pension increased in real (CPI-adjusted) sums by almost a factor of 5 between 1995 and 2006. The monthly pension in U.S. dollars was around $20–$25 until 2000, then dropped to $15–$20 between 2001 and 2004, and now is $64. The minimum wage was raised to $34.31 in November 2011. Assuming that the average wages in the country are at a level of 3-4 times the monthly pension, we estimate the wages in 2006 at $100–$250 per month, or $3–$8 per day. 
Question: How many years did it take for pensions to increase by a factor of almost 5?

Passage: The first archaeological findings around the lake belong to nomadic people living in the area in prehistoric types. The first settlements discovered date from the Copper Age. The area was later under the control of the Ligures, later replaced by the Celts. The latter were in turn conquered by the Romans, who called the lake Verbanus Lacus or Lacus Maximus. After the fall of the Western Roman Empire, the lake was under different dominations. Most of the current settlements originated in the Middle Ages, when the lake was under the Della Torre, Visconti, the Borromeo and Habsburg families. Methane was first discovered and isolated by Alessandro Volta as he analysed marsh gas from Lake Maggiore, between 1776 and 1778. In 1936, a Bugatti Type 22 Brescia Roadster, built 1925, was sunk in the lake by employees of Zürich architect Marco Schmucklerski, when Swiss custom officials investigated whether he had paid taxes on the car. The Bugatti was attached to an iron chain making it possible to recover it once the investigation was over, yet that never happened. When the chain corroded, the car sunk to the lake bed, where it was rediscovered on 18 August 1967 by local diver Ugo Pillon and became a favourite target for divers thereafter. When one of the divers, Damiano Tamagni, was killed in a hold-up on 1 February 2008, his friends from the Ascona divers' club decided to lift and sell the carwreck to raise funds for a yet to be created foundation named after the victim. The remains of the Bugatti were recovered on 12 July 2009. The sale took place at the Retro Mobile classic car exhibition in Paris on 23 January 2010. It was sold for €260,500.
