TASK DEFINITION: This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
PROBLEM: Passage: The Greek Navy was relatively modern, strengthened by the recent purchase of numerous new units and undergoing reforms under the supervision of a British mission. Invited by Prime Minister Venizelos in 1910, the mission began its work upon its arrival in May 1911. Granted extraordinary powers and led by Vice Admiral Lionel Grand Tufnell, it thoroughly reorganized the Navy Ministry and dramatically improved the number and quality of exercises in gunnery and fleet maneuvers. In 1912, the core unit of the fleet was the fast armoured cruiser Georgios Averof, completed in 1910 and, at that time, the fastest and most modern warship in the combatant navies. It was complemented by three rather antiquated battleships of the Hydra class. There were also eight destroyers built in 1906-1907, and six new destroyers that were hastily bought in summer 1912 as the imminence of war became apparent. Nevertheless, at the outbreak of the war, the Greek fleet was far from ready. The Ottoman battlefleet retained a clear advantage in number of ships, speed of the main surface units and, more importantly, in the number and caliber of the ships' guns. In addition, as the war caught the fleet in the middle of its expansion and reorganization, fully a third of the fleet  only reached Greece after hostilities had started, forcing the navy to reshuffle crews, who consequently suffered from lacking familiarization and training time. Coal stockpiles and other war stores were also in short supply, while the Georgios Averof had arrived with barely any ammunition, and would remain so until late November.
Question: What is the latter year when eight destroyers were built?

SOLUTION: date

PROBLEM: Passage: In Imielin (4-5 September), 28 Poles were killed; in Kajetanowice (5 September), 72 civilians were massacred in revenge for two German horses killed by German friendly fire; Trzebinia (5 September), 97 Polish citizens; Piotrków Trybunalski (5 September), Jewish section of the city was set on fire; Będzin (8 September), two hundred civilians burned to death; Kłecko (9-10 September), three hundred citizens executed; Mszadla, Łódź Voivodeship (10 September), 153 Poles; Gmina Besko (11 September), 21 Poles; Kowalewice, Łódź Voivodeship (11 September), 23 Poles; Pilica (12 September); 36 Poles, 32 of them Jewish; Olszewo, Gmina Brańsk (13 September), 13 people (half of the village) from Olszewo and 10 from nearby Pietkowo including women and children stabbed by bayonets, shot, blown up by grenades, and burned alive in a barn; Mielec (13 September), 55 Jews burned to death; Piątek, Łódź Voivodeship (13 September), 50 Poles, seven of them Jews. On 14-15 September about 900 Polish Jews, mostly intelligentsia, were targeted in parallel shooting actions in Przemyśl and in Medyka; this was a foreshadowing of the Holocaust to come. Roughly at the same time, in Solec Kujawski (14 September), 44 Poles killed; soon thereafter in Chojnice, 40 Polish citizens; Gmina Kłecko, 23 Poles; Bądków, Łódź Voivodeship, 22 Poles; Dynów, two hundred Polish Jews. Public executions continued well beyond September, including in municipalities such as Wieruszów County, Gmina Besko, Gmina Gidle, Gmina Kłecko, Gmina Ryczywół, and Gmina Siennica, among others.

PROBLEM: Passage: Sunday Night Football featured a Divisional Playoff rematch from 2015 as the Seattle Seahawks faced the Carolina Panthers in CenturyLink field.

This was the first time that Seattle had scored 40 points in a regular season game since the 2013 season. Seattle improved their record to 8-3-1 of season. The win was not without cost, however, as star safety Earl Thomas broke his leg early in the second quarter, knocking him out for the rest of the season.
