Question: Who produced the film that Martino appeared in that was shown on BBCOne on Christmas Eve 2018? Passage 1:Despite the weakness of the Song military, they managed to slow the Mongol Empire advance for decades. The Song resistance led to the death of Möngke Khan, in 1259, at Diaoyu Fortress. The resulting withdrawal of the Mongol forces, for the customary kurultai to select a new Khan, ultimately led to the Toluid Civil War which divided the Mongol Empire. Möngke's brother, Kublai Khan, who already controlled Mongolia and China's northern territories, formerly part of the Jin Empire, declared himself Emperor of China and founded the Yuan dynasty. Kublai renewed the Mongol campaign against the Song eventually capturing the fortified cities of Fancheng, and Xiangyang during the Battle of Xiangyang in 1273, allowing his armies to advance deep into Song territory and seize its capital. On 19 March 1279, the Song chancellor Lu Xiufu committed suicide with the eight-year-old Zhao Bing after the defeat of the remaining Song forces at the Battle of Yamen bringing an end to the Song Dynasty and marking the beginning of a century of Mongolian rule over China before the establishment of the Ming Dynasty by the House of Zhu and a return to Han rule.

 Passage 2:Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15. Here, US 6 joins I-84 West and Route 67 continues to the southeast becoming a 2-lane road once again. After intersecting Route 188, it enters Oxford, where it has a junction with the west end of Route 42. In Seymour, it passes the western end of Route 313 before crossing the Naugatuck River. On the east shore of the river, it meets the Route 8 expressway at Exits 21 & 22. It then passes the northern end of Route 115 before heading into Woodbridge, where Route 67 ends at Route 63. 
 Passage 3:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

Question: Which location now has the largest population, where McCulloch was born or where he died? Passage 1:Meanwhile, the motto frappez fort, frappez vite (French, strike hard, strike fast) was carried out at once by the regular forces. On 19 July, Cromwell made the final arrangements at Berwick-on-Tweed. Major-General Thomas Harrison, a gallant soldier and an extreme English Independent, a Fifth Monarchist, was to command the regular and auxiliary forces left in England, and to secure the Commonwealth against Royalists and Presbyterians. Cromwell took with him Lieutenant-General Charles Fleetwood and Major-General John Lambert, and his forces numbered about 10,000 foot and 5,000 horse. His opponent David Leslie (his comrade of Marston Moor) had a much larger force, but its degree of training was inferior, it was more than tainted by the political dissensions of the people at large, and it was, in great part at any rate, raised by forced enlistment. On 22 July, Cromwell crossed the river Tweed. He marched on Edinburgh by the sea coast, through Dunbar, Haddington and Musselburgh, living almost entirely on supplies landed by the fleet which accompanied him, for the country itself was incapable of supporting even a small army, and on 29 July, he found Leslie's army drawn up and entrenched in a position extending from Leith to Edinburgh.
 Passage 2:Surgical tape or medical tape is a type of pressure-sensitive adhesive tape used in medicine and first aid to hold a bandage or other dressing onto a wound. These tapes usually have a hypoallergenic adhesive which is designed to hold firmly onto skin, dressing materials, and underlying layers of tape, but to remove easily without damaging the skin. They allow air to reach the skin ("breathable"). Some breathable tapes such as Kinesiology Tape, and other elastic bandages with adhesive are made of cotton. Surgical tape is often white because it contains zinc oxide, which is added to help prevent infections. Tapes made of microporous material, such as 3M Micropore, are widely used.
 Passage 3:McCulloch was born in Bonnybridge, Stirlingshire, Scotland, to Agnes (née Morrison) and Thomas McCulloch. He left school at an early age to work as a coal miner, and then later enlisted in the British Army. He served in Africa and Europe during World War I, holding the rank of battalion sergeant major, and was both mentioned in despatches and awarded the Military Medal. After the war's end, McCulloch returned to coal mining. He emigrated to Western Australia in 1928, and settled in Kalgoorlie, working as a truck driver and municipal employee. He served as secretary of the local trades hall from 1943 to 1949. McCulloch entered parliament at the 1949 Hannans by-election, caused by the death of David Leahy. He was re-elected at the 1950 and 1953 state elections. He left parliament when his seat was abolished prior to the 1956 election, and died in Perth in March 1971, aged 77. McCulloch had married Agnes Burt Montgomery in 1921, with whom he had two children.
