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.

Input: Consider Input: 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?

Output: date

Input: Consider Input: Passage: The followers of Bokero's movement were poorly armed with spears and arrows, sometimes poisoned. However, they were numerous and believed that they could not be harmed because the Germans' bullets would turn to water. They marched from their villages wearing millet stalks around their foreheads. Initially, they attacked small outposts and damaged cotton plants. On 31 July 1905, Matumbi tribesmen marched on Samanga and destroyed the cotton crop as well as a trading post. Kinjikitile was arrested and hanged for treason. Before his execution, he declared that he had spread the medicine of the rebellion throughout the region. On 14 August 1905, Ngindo tribesmen attacked a small party of missionaries on a safari; all five, including Bishop Spiss were speared to death. Throughout August the rebels moved from the Matumbi Hills in the southern part of what is now Tanzania and attacked German garrisons throughout the colony. The attack on Ifakara, on 16 August, destroyed the small German garrison and opened the way to the key fortification at Mahenge. Though the southern garrison was quite small , their fortifications and modern weapons gave them an advantage. At Mahenge, several thousand Maji Maji warriors marched on the German cantonment, which was defended by Lieutenant Theodor von Hassel with sixty native soldiers, a few hundred loyal tribesmen, and two machine guns. The two attacking tribes disagreed on when to attack and were unable to co-ordinate. The first attack was met with gunfire from 1000 m; the tribesmen stood firm for about fifteen minutes, then they broke and retreated. After the first attack, a second column of 1,200 men advanced from the east. Some of these attackers were able to get within three paces of the firing line before they were killed.
Question: How many days passed between the Matumbi tribesmens march on Samanga and the attack on missionaried by the Ngindo?

Output: number

He established a camp around his red tent to the east of the island of Goa, the infantry distributed ahead of Benastarim and the artillery placed into position to counter-fire the Portuguese batteries. The artillery of Bijapur began battering the fort, which was constantly repaired during the night. Throughout the Portuguese lines by the river banks, the Viceroy ordered torches and bonfires be lit on isolated positions by night, to give the impression of readiness and encourage the enemy to waste ammunition firing on them.
