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.

[EX Q]: 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 former year when eight destroyers were built?
[EX A]: date

[EX Q]: Passage: Trying to snap a two-game skid, the 49ers stayed at home for a Saturday night interconference battle with the Cincinnati Bengals.  With QB Trent Dilfer out with an injury, back-up Shaun Hill would be making his first career start. After a scoreless first quarter, the Niners drew first blood in the second quarter as Hill got a 3-yard TD run.  However, the Bengals would take the lead as kicker Shayne Graham managed to get a 24-yard field goal, while QB Carson Palmer completed a 52-yard TD pass to WR Chris Henry.  The Niners would end the half as Hill completed a 17-yard TD pass to TE Vernon Davis. In the third quarter, San Francisco increased their lead with kicker Joe Nedney managing to get a 29-yard and a 38-yard  field goal.  In the fourth quarter, Cincinnati tried to mount a comeback as Graham kicked a 35-yard field goal.  Fortunately, the Niners' defense held on for the impressive victory. With the win, the 49ers improved to 4-10.  With the Rams' loss to the Packers, the Niners now sit in 3rd place in the NFC West.

[EX Q]: Passage: The Knights, under the leadership of Heinrich von Plotzke, agreed to aid Bogusza, and a force of 100 knights and 200 supporters, led by Günther von Schwarzburg, arrived at the castle around August. While historians agree that the castle as well as the adjacent town were in the hands of the Teutonic Knights by late November 1308 the number of casualties and the extent of destruction is debated. Peter Oliver Loew writes that for a long time German historians accepted the version of events given by Teutonic Knights, and didn't accept a high number of people murdered, with the number given between 60 and 100 victims Błażej Śliwiński, based on several sources argues that the number of murdered was very high, even if not 10,000. According to Peter Oliver Loew the exact numbers can never be established, however he agrees that all available data confirms that the city was destroyed during the conquest.
