question: 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.

question: After battling the Super Bowl champions in Week 9, the winless Raiders went back home for Week 10 to take on their divisional rival and the defending AFC Champion Denver Broncos for the first time all year. Broncos QB Peyton Manning was immediately picked off by cornerback D.J. Hayden on his second pass of the game 30 seconds in. Taking over near midfield, the Raiders got down to the Denver 23, but were forced to kick a 41-yard field goal, which Janikowski was successful on. Broncos kicker Brandon McManus responded with a field goal of his own, and the game was tied at 3 apiece. In the second quarter, McManus added another field goal and, later in the period, the Raiders intercepted Manning again; this time, it was Justin Tuck. Oakland scored a touchdown off the turnover and took a 10-6 lead on a Derek Carr 5-yard touchdown pass to wide receiver Brice Butler. However, after 2 unsuccessful drives for each team, Carr was  intercepted by Denver cornerback Bradley Roby and the Broncos stormed back with two quick touchdowns. Both touchdowns were passes by Manning to C.J. Anderson and Emmanuel Sanders of 51 and 32 yards, respectively. Denver led 20-10 at the half. In the second half, Oakland's offensive miscues continued as Khalif Barnes fumbled at his own 13-yard line, and the Broncos wasted no time as Manning's 10-yard pass to Julius Thomas put Denver up by 17. Oakland's next possession ended in a punt, and Manning went right back to Thomas for another touchdown, Peyton's fourth of the day and second from 32 yards out. Carr was picked off again, the Broncos scored yet another touchdown on Manning's fifth of the game and second to Emmanuel Sanders, and the visitors took a commanding 41-10 lead. Down 31 points, the Raiders headed into the 4th quarter getting embarrassed by the potent Denver offense, and were unable to do much more than score an insignificant touchdown with 53 seconds left. The Broncos left Oakland with a 41-17 win and moved to 7-2 on the season. Meanwhile, the Raiders' woes continued as their record fell to 0-9.

question: Hoping to rebound from their tough divisional road loss to the 49ers, the Cardinals played their Week 2 homeopener against their NFC West foe, the Seattle Seahawks.  In the first quarter, the Cards took to the skies first with kicker Neil Rackers getting a 28-yard field goal for the only score of the period.  In the second quarter, Arizona continued to pound away with QB Matt Leinart completing a 30-yard TD pass to TE Leonard Pope, along RB Edgerrin James getting a 17-yard TD run.  The Seahawks would get their only score of the half with QB Matt Hasselbeck completing a 24-yard TD pass to WR Nate Burleson. In the third quarter, the Cardinals' lead was gone with Seattle RB Shaun Alexander getting a 16-yard TD run and kicker Josh Brown getting a 28-yard field goal.  In the fourth quarter, the Cards trailed as Brown got another 28-yard field goal.  Arizona responded with Rackers kicking a 52-yard field goal.  Late in the game, the Cards defense managed to recover a Seahawk fumble.  It would eventually turn into Rackers' 4th career game-winning field goal as made it from 42 yards out as time ran out.
