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: Persia attempted to ratify the Treaty of Constantinople , by demanding that the Ja'fari, also known as the Imamiyyah was to be accepted as a fifth legal sect of Islam. In 1743, Nader Shah declared war on the Ottoman Empire. He demanded the surrender of Baghdad. The Persians had captured Baghdad in 1623 and Mosul in 1624, but the Ottomans had recaptured Mosul in 1625 and Bagdad in 1638. The Treaty of Zuhab in 1639 between the Ottoman Empire and the Safavid Empire had resulted in peace for 85 years. After the fall of the Safavid Dynasty, Russia and the Ottoman Empire agreed to divide the northwest and the Caspian region of Persia, but with the advent of Nader Shah, the Russians and the Turks withdrew from the region. Nader Shah waged war against the Ottomans from 1730 to 1736 but it ended with a stalemate. Nader Shah afterwards turned east and declared war on the Moghul Empire and invaded India, in order to refund his wars against the Ottomans.
Question: How many years did Nader Shah wage war against the Ottomans?

Output: number
