Question: Passage: 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.

Question: Passage: Coming off their MNF home win over the Jets, the Chargers flew to Oakland-Alameda County Coliseum for a Week 4 AFC West duel with the Oakland Raiders.  In the first quarter, the 'Bolts trailed early as Raiders kicker Sebastian Janikowski got a 22-yard field goal, along with Safety Gibril Wilson sacking QB Philip Rivers in his endzone for a safety.  In the second quarter, San Diego continued to trail as QB JaMarcus Russell completed a 63-yard TD pass to TE Zach Miller, along with Janikowski's 28-yard field goal. In the third quarter the Chargers began to rally as kicker Nate Kaeding made a 28-yard field goal.  In the fourth quarter, the 'Bolts continued their rally as Rivers completed a 9-yard TD pass to TE Antonio Gates, along with RB LaDainian Tomlinson getting a 13-yard TD run (with a successful 2-point conversion pass from Rivers to RB Darren Sproles).  Oakland tried to respond as Janikowski got a 32-yard field goal, yet San Diego completed its comeback with Kaeding making a 47-yard field goal and Tomlinson rushing for a 41-yard TD run. Notable: Through 15 games against a single opponent, LaDainian Tomlinson set a new record in touchdowns and yards against an opponent previously held by Barry Sanders, 1,763 yards, and Marcus Allen, 20 Touchdowns, respectively, by totaling 1,815 yards and 21 touchdowns.

Question: Passage: The first Azov campaign began in the spring of 1695. Peter the Great ordered his army  to advance towards Azov. The army comprised crack regiments and the Don Cossacks and was divided into three units under the command of Franz Lefort, Patrick Gordon and Avtonom Golovin. Supplies were shipped down the Don from Voronezh.In 1693 the Ottoman garrison of the fortress was 3,656, of whom 2,272 were Janissaries.Between June 27-July 5 the Russians blocked Azov from land but could not control the river and prevent resupply. After two unsuccessful attacks on August 5 and September 25, the siege was lifted on October 1. Another Russian army  under the command of Boris Sheremetev set out for the lower reaches of the Dnieper to take the Ottoman forts there. The main fort at Gazi-Kerman was taken when its powder magazine blew up, as well as Islam-Kerman, Tagan and Tavan, but the Russians were not able to hold the area and withdrew most of their forces. By the Treaty of Constantinople  the remaining Russians were withdrawn and the lower Dnieper was declared a demilitarized zone.
