PROBLEM: Passage: The Russo-Turkish War of 1735-1739 between Russia and the Ottoman Empire was caused by the Ottoman Empire's war with Persia and continuing raids by the Crimean Tatars. The war also represented Russia's continuing struggle for access to the Black Sea. In 1737, Austria joined the war on Russia's side, known in historiography as the Austro-Turkish War of 1737-1739.

PROBLEM: Passage:  Hoping to rebound from their loss to the Patriots, the Raiders stayed at home for a Week 16 duel with the Houston Texans.  Oakland would get the early lead in the first quarter as quarterback JaMarcus Russell completed a 20-yard touchdown pass to rookie wide receiver Chaz Schilens.  The Texans would respond with fullback Vonta Leach getting a 1-yard touchdown run, yet the Raiders would answer with kicker Sebastian Janikowski getting a 33-yard and a 30-yard field goal.  Houston would tie the game in the second quarter with kicker Kris Brown getting a 53-yard and a 24-yard field goal. Oakland would take the lead in the third quarter with wide receiver Johnnie Lee Higgins catching a 29-yard touchdown pass from Russell, followed up by an 80-yard punt return for a touchdown.  The Texans tried to rally in the fourth quarter as Brown nailed a 40-yard field goal, yet the Raiders' defense would shut down any possible attempt.

PROBLEM: Passage: The Broncos spotted the Colts a 10-0 lead, with quarterback Jacoby Brissett rushing for a 7-yard touchdown, followed in the second quarter by a 45-yard field goal by placekicker Adam Vinatieri. The former occurred after an interception of quarterback Trevor Siemian on the Broncos' initial possession. Siemian was knocked out of the game late in the first quarter due to a shoulder injury, after being sacked by Colts' linebacker Barkevious Mingo. Brock Osweiler took over early in the second quarter, and got the Broncos on the scoreboard just before halftime, with an 18-yard touchdown run. A 39-yard field goal by Vinatieri on the Colts' initial possession of the second half increased the lead to 13-7; however, the Broncos' defense held the Colts scoreless for the remainder of the game. The Broncos claimed the lead for good with a pair of touchdown passes from Osweiler &#8212; a 22-yarder to wide receiver Cody Latimer, followed by a 54-yarder to tight end Jeff Heuerman (with a successful two-point conversion). Placekicker Brandon McManus added a 40-yard field goal with 5:18 remaining in the game, on a drive that chewed up 9:40 off the clock. It was the Broncos' only road win of the season. The Broncos snapped a 6-game losing streak in Indianapolis, dating back to 2003 (including the playoffs).
