Q: With a chance to clinch a playoff spot for the first time since 2002, the Raiders traveled to Kansas City for a crucial Thursday night matchup to determine the AFC West division lead. The Raiders needed a win and a Miami Dolphins loss or a win and a Denver Broncos loss to clinch a playoff berth. Oakland started well, recovering a muffed fumble by Tyreek Hill on a punt following their first drive and setting them up at the Kansas City 38-yard line. However, the Raiders had to settle for a field goal by Sebastian Janikowsi to take the early 3-0 lead. It would be the last lead the Raiders enjoyed on the night. Oakland's offense could muster little for most of the first half including after the Raider defense stopped KC on a fourth and one at the Oakland 27. The Chiefs took the lead early in the second quarter on a 36-yard pass from Alex Smith to Hill to make the score 7-3. After a four-and-out possession for the Raiders, the Chiefs again went down the field scoring on a Charcandrick West three-yard touchdown run. Following another Raiders short offensive possession, Hill returned a punt 78 yards for a touchdown to extend the Chief lead to 21-3. With six minutes remaining in the half, the Raiders went up-tempo and moved the ball down the field capping the drive with a one-yard touchdown run by Latavius Murray with 14 seconds remaining. At the half, the Raiders trailed 21-10. To begin the second half, the Raider defense stepped up intercepting Smith on the second play of the half and giving the offense the ball at the KC 23. However, the offense was shut down by the KC defense and settled for another Janikowski field goal, bringing them within a touchdown of the Chiefs at 21-13. On the next offensive play for the Chiefs, Khalil Mack sacked and stripped Smith of the ball and the Raiders recovered at the KC 18-yard line. The offense again managed little and was forced to settle for a field goal attempt. However, a bad snap resulted in Marquette King being tackled for three-yard loss. Both offenses mustered very little for the remainder of the game. With seven minutes left in the game, the Raiders needed a touchdown to tie and moved down to the KC 19-yard line, but were stopped on fourth down and the Chiefs ran the clock out. Derek Carr struggled mightily with his accuracy on the night, only completing 17 of his 41 pass attempts for 117 yards. He often missed open receivers or badly threw behind receivers. Carr admitted he had a bad night saying, "Obviously, we didn't do enough." The loss ended the Raiders six-game win streak and gave the Chiefs the lead in the division with a 2-0 record over the Raiders. The Raiders, still, in prime playoff position, would have to finish ahead of the Chiefs to win the division.
How many points did the Chiefs lead by at halftime?
A: 11

Q: After a few years of peace, the Ottoman Empire attacked the Habsburg Empire again. The Turks almost captured the Empire's capital of Vienna, but king of Poland John III Sobieski led a Christian alliance that defeated them in the Battle of Vienna, which shook the Ottoman Empire's hegemony in south-eastern Europe. A new Holy League was initiated by Pope Innocent XI and encompassed the Holy Roman Empire , joined by the Venetian Republic and Poland in 1684 and the Tsardom of Russia in 1686. Ottomans suffered two decisive defeats against the Holy Roman Empire: the second Battle of Mohacs in 1687 and the Battle of Zenta a decade later, in 1697. On the smaller Polish front, after the battles of 1683 , Sobieski, after his proposal for the League to state a major coordinated offensive, undertook a rather unsuccessful offensive in Moldavia in 1686, with the Ottomans refusing a major engagement and harassing the army. For the next four years Poland would blockade the key fortress at Kamenets, and Ottoman Tatars would raid the borderlands. In 1691, Sobieski undertook another expedition to Moldavia, with slightly better results, but still with no decisive victories. The last battle of the campaign was the Battle of Podhajce in 1698, where Polish hetman Feliks Kazimierz Potocki defeated the Ottoman incursion into the Commonwealth. The League won the war in 1699 and forced the Ottoman Empire to sign the Treaty of Karlowitz. The Ottomans lost much of their European possessions, with Podolia returned to Poland.
