Input: In 1970, seagoing pilots became retrospectively insurable, and gained full social security as members of the Non-Manual Workers Insurance Institute. That same year, a special regulation came into force for District Master Chimney Sweeps, making them fully insurable under the Craftsmans Insurance Scheme. An increase was made in tax-free allowances for children, which enabled 1,000,000 families to claim an allowance for the second child, compared to 300,000 families previously. The Second Modification and Supplementation Law (1970) increased the allowance for the third child from DM 50 to DM 60, raised the income-limit for the second child allowance from DM 7,800 to DM 13,200; subsequently increased to DM 15,000 by the third modification law (December 1971), DM 16,800 by the fourth modification law (November 1973), and to DM 18,360 by the fifth modification law (December 1973). A flexible retirement age after 62 years was introduced (1972) for invalids and handicapped persons, and social assistance was extended to those who previously had to be helped by their relatives. From 1971, special subventions were provided to enable young farmers to quit farming "and facilitate their entry into the non-agricultural pension system by means of back payments."

Question: How many more DM was in the fifth modification than the fourth?

Input: Ali Pasha, one of Murad's most favoured commanders, left Uskup in June 1444 with an army of 25,000-40,000 troops and headed in Albania's direction. Having brought together an army of 15,000 men from the League of Lezhe, Skanderbeg exhorted to his soldiers the importance of the upcoming campaign. Orders were given for the distribution of soldiers' pay and for religious services to be held. Afterwards, Skanderbeg and his army headed towards the planned place of battle in Lower Dibra, which is thought to be the Plain of Shumbat, then called the Plain of Torvioll, north of Peshkopi. On the way there, he marched through the Black Drin valley and appeared at the expected Ottoman entry point. Skanderbeg had chosen the plain himself: it was 11.2 kilometres long and 4.9 kilometres wide, surrounded by hills and forests. After camping near Torvioll, Skanderbeg placed 3,000 men under five commanders, Hamza Kastrioti, Muzaka of Angelina, Zecharia Gropa, Peter Emanueli, and John Musachi, in the surrounding forests with orders to attack the Ottoman wings and rear only after a given signal. While Skanderbeg was preparing his ambush, the Ottoman Turks under Ali Pasha arrived and encamped opposite his forces. The night before the battle, the Ottomans celebrated the coming day, whereas the Albanians extinguished all their campfires and those who were not on guard were directed to rest. Parties of Ottomans made approaches to the Albanian camp and provoked Skanderbeg's soldiers, but they remained quiet. Skanderbeg sent out a scouting party to obtain information about the Ottoman army and ordered his cavalry to engage in small skirmishes.

Question: What was the name of the plain was chose for battle at the time of the battle?

Input: With the rest of Week 16's games being played on Christmas Eve, the Jets, due to losses by Jacksonville and Cincinnati, controlled their own playoff destiny with two victories. The game was played in a driving rainstorm as both teams struggled to move the ball early. With 49 seconds remaining in the first quarter, Mike Nugent was ready to attempt a 34-yard field goal, but holder Ben Graham could not handle the snap in the slippery conditions, and the Jets were denied. It was the second straight week Graham had flubbed a snap, but this one could be blamed on the wet conditions. The two teams would trade punts for the rest of the half. In the third quarter, Dolphins coach Nick Saban inserted backup quarterback Cleo Lemon into the game, replacing an ineffective Joey Harrington. Finally, the Jets went on a drive with 6:15 left in the third quarter, with Chad Pennington scrambling for 15 yards and moving into the Dolphins' red zone when Yeremiah Bell was flagged for pass interference. Nugent knocked in a 22-yard field goal for the first points of the game. But Lemon rallied Miami, completing two long passes to Randy McMichael and Ronnie Brown picking up a long run before Lemon tossed a 7-yard touchdown pass to McMichael, and the Dolphins led 7-3 with 13:26 left in the game. Pennington showed poise in leading the Jets back to take the lead, completing key passes to Brad Smith and Leon Washington before finding Cotchery on a 31-yard completion to the Miami 1-yard line, but the Jets challenged, saying that Cotchery was brought down after he broke the plane of the end zone, and the referee agreed, giving the Jets a 10-7 lead with 8:04 remaining in the game. Miami was then forced to punt, but caught a break when Donnie Jones' kick bounced off the elbow of Jets linebacker Brad Kassell, and long snapper John Denney recovered at the Jets' 42-yard line. Lemon led Miami downfield, completing key passes to Derek Hagan and Sammy Morris before Mare tied the game with a 25-yard field goal. With 2:09 to play, the Jets' biggest play of the season took place. Pennington flipped a short screen pass to Washington, who found a hole and scampered 64 yards down to the Miami 16-yard line. After three runs by Kevan Barlow, Nugent kicked a 30-yard field goal with 10 seconds to play, and the Jets had their biggest win of the year.

Question:
how many yards did Mare tie the game with?
