Problem: LaDainian Tomlinson ran in two TDs and threw for one to give San Diego its third straight comeback win. He then had 21 rushing touchdowns on the year and brought his career QB record to 7 completions out of 10 attempts with 6 touchdowns. Philip Rivers, on the other hand, struggled completing 14 of 31 passes and throwing for only a 133 yards with no touchdowns and 1 interception. The Chargers swept the Raiders and had then won seven straight from Oakland. The scoring started with the Raiders making it 7-0 after a 1-yard pass from Aaron Brooks to Reshard Lee. The Chargers answered back when Antonio Cromartie returned the ensuing kick 91 yards, which set up a 2-yard run by LT to tie the score at 7-7 going into the half. The Raiders took the lead again on a catch and run by rookie John Madsen that set up a 2-yard pass from Brooks to Madsen to make it 14-7 Oakland. On 4th and 2, Rivers passed to Vincent Jackson for a first down, but Jackson proceeded to get up and throw the ball forward in celebration, but he hadn't been touched down. The initial ruling was that it was a fumble and Oakland's ball; however, after the officials got together for a conference they declared that since it was an illegal forward fumble that it was technically an illegal forward pass and San Diego was then given back the ball and penalized 5 yards, which was still enough for the first down. The game continued and on the next play, Rivers pitched the ball to Tomlinson as if it were a run play but then threw the ball to an open Antonio Gates to tie the score at 14-14. After forcing Oakland to punt, the Chargers drove down field and LT ran it in from 10 yards out to give the Chargers the 21-14 win. With the win, the Chargers had won 7 straight games over the Raiders and improved their record to 9-2.

Which team had 21 points by the end of the game?
Answer: Chargers the 21-14 win

Problem: Returning to Candlestick Park, the 49ers geared up for a rematch against Brett Favre and his new team. The game started when the 49ers attempted an onside kick, recovered by the Jets. Later, the 49ers went up first as Shaun Hill completed a pass to Jason Hill that was fumbled at the goal line and recovered by offensive tackle Joe Staley for the touchdown. Then, Brett Favre ran for a 2-yard touchdown. The 49ers retook the lead as Shaun Hill completed a touchdown screen pass to Frank Gore. After half-time, Thomas Jones plowed through the 49ers secondary to get a 17-yard score. On the ensuing 49ers possession, a Shaun Hill touchdown pass to Delanie Walker was called back, and the 49ers settled for a Joe Nedney 32-yard field goal. In the fourth quarter, the 49ers cemented their lead when Shaun Hill completed a 3-yard touchdown pass to a diving Bryant Johnson. The Jets had enough time to make a late comeback, but a Brett Favre deep pass was intercepted by Walt Harris. The 49ers ran down the clock and punted, and the Jets did not have sufficient time to attempt the comeback. The 49ers fumbled the ball a total of 5 times, although, fortunately for them, only one was lost. With the win, the 49ers improved to 5-8. However, they were officially eliminated from playoff contention with the Arizona Cardinals win against the St. Louis Rams, clinching the NFC West for Arizona.

Which team won the NFC West?
Answer: Arizona Cardinals

Problem: This drop was caused by a combination of sharply lower petroleum prices in world markets and voluntary production cuts in Brunei. The GDP recovered somewhat since 1986, growing by 12% in 1987, 1% in 1988, and 9% in 1989. In recent years, GDP growth was 3.5% in 1996, 4.0% in 1997, 1.0% in 1998, and an estimated 2.5% in 1999. However, the 1999 GDP was still only about $4.5 billion, well below the 1980 peak.

How many more percent was growth of petroleum prices in 1986 than 1987?
Answer:
11
