Question: Write an article that answers the following question: Which captives were freed?
Article: On 21 September, 2015, Canadians Robert Hall and John Ridsdel, as well as Norwegian Kjartan Sekkingstad, and Marites Flor; a Filipino woman, were abducted on Samai island near Davao. Ridsdel was beheaded by Abu Sayyaf on 25 April 2016 following a ransom deadline. ASG reportedly demanded more than $8.1 million for Ridsdel and the others. On 3 May, 2016, a video of the Ridsdel execution was released, along with new demands for the remaining hostages. A masked captor said, "Note to the Philippine government and to the Canadian government: The lesson is clear. John Ridsdel has been beheaded. Now there are three remaining captives here. If you procrastinate once again the negotiations, we will behead this all anytime". On 15 May, Hall appeared in a new video, announcing that he and Norwegian Kjartan Sekkingstad would be decapitated at 3pm on Monday 13 June absent a ransom of $16 million. Both hostages wore orange coveralls, similar to hostages in videos produced by ISIL, to which Abu Sayyaf had previously pledged allegiance. The deadline passed. Hall was beheaded. On 24 June, Abu Sayyaf released Filipina Marites Flor. She was subsequently flown to Davao to meet President-elect Rodrigo Duterte. Duterte said he directed negotiations with the Abu Sayyaf. He did not elaborate. On 17 September, 2016, remaining hostage Norwegian Kjartan Sekkingstad was released on Jolo island. Abu Ramie, an ASG spokesman, claimed $638,000 was paid as ransom.

Question: Write an article that answers the following question: How many years passed between the first Tatar raid and the last Tatar raid?
Article: The Crimean-Nogai raids were slave raids carried out by the Khanate of Crimea and by the Nogai Horde into the region of Rus' then controlled by the Grand Duchy of Moscow , by the Tsardom of Russia , by the Russian Empire and by the Grand Duchy of Lithuania . These raids began after Crimea became independent about 1441 and lasted until the peninsula came under Russian control in 1774. Their main purpose was the capture of slaves, most of whom were exported to the Ottoman slave markets in Constantinople or elsewhere in the Middle East. The raids were an important drain of the human and economic resources of eastern Europe. They largely inhabited the settlement of the "Wild Fields" - the steppe and forest-steppe land which extends from a hundred or so miles south of Moscow to the Black Sea and which now contains most of the Russian and Ukrainian population. The raids also played an important role in the development of the Cossacks. Estimates of the number of people involved vary: according to Alan W. Fisher the number of people deported from the Slavic lands on both sides of the border during the 14th to 17th centuries was about 3 million. Michael Khodarkhovsky estimates that 150,000 to 200,000 people were abducted from Russia in the first 50 years of the 17th century. The first major Tatar raid for slaves occured in 1468 and was directed into Galicia. Crimean Khan Devlet I Giray even managed to burn down Moscow during the 1571 campaign. The last raid into Hungary by the Crimean Tatars took place in 1717. In 1769 a last major Tatar raid, which took place during the Russo-Turkish War, saw the capture of 20,000 slaves.

Question: Write an article that answers the following question: Which team failed to get any first half field goals?
Article: With their MNF home win over the Jaguars fresh in their minds, the Texans flew to Lambeau Field for a Week 14 interconference duel with the Green Bay Packers. Houston shot early in the first quarter as QB Matt Schaub completed a 58-yard TD pass to wide receiver Kevin Walter. The Packers would respond in the second quarter with QB Aaron Rodgers completing a 20-yard touchdown pass to TE Donald Lee, yet the Texans would close out the half with a 30-yard field goal from kicker Kris Brown. Houston would get the third quarter's only points as Brown got a 41-yard field goal. Green Bay would answer in the fourth quarter as RB Ryan Grant got a 6-yard touchdown run, yet the Texans replied with Schaub completing an 11-yard touchdown pass and a 2-point conversion pass to wide receiver Andre Johnson. The Packers would tie the game as Rodgers completed a 9-yard touchdown pass to wide receiver Jordy Nelson. Fortunately, Houston got the last laugh as Brown nailed the game-winning 40-yard field goal.

Question: Write an article that answers the following question: How many years did the last naval war last for?
Article: The Vikings also fought several sea battles among themselves. This was normally done by binding the ships on each side together, thus essentially fighting a land battle on the sea. However the fact that the losing side could not easily escape meant that battles tended to be hard and bloody. The Battle of Svolder is perhaps the most famous of these battles. As Arab power in the Mediterranean began to wane, the Italian trading towns of Genoa, Pisa, and Venice stepped in to seize the opportunity, setting up commercial networks and building navies to protect them. At first the navies fought with the Arabs , but then they found themselves contending with Normans moving into Sicily, and finally with each other. The Genoese and Venetians fought four naval wars, in 1253-1284, 1293-1299,1350-1355, and 1378-1381. The last ended with a decisive Venetian victory, giving it almost a century to enjoy Mediterranean trade domination before other European countries began expanding into the south and west. In the north of Europe, the near-continuous conflict between England and France was characterised by raids on coastal towns and ports along the coastlines and the securing of sea lanes to protect troop-carrying transports. The Battle of Dover in 1217, between a French fleet of 80 ships under Eustace the Monk and an English fleet of 40 under Hubert de Burgh, is notable as the first recorded battle using sailing ship tactics. The battle of Arnemuiden , which resulted in a French victory, marked the opening of the Hundred Years War and was the first battle involving artillery. However the battle of Sluys, fought two years later, saw the destruction of the French fleet in a decisive action which allowed the English effective control of the sea lanes and the strategic initiative for much of the war.
