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: In 1570 MacGill reluctantly accepted appointment as Provost of Edinburgh. In November 1571, during the War between Leith and Edinburgh when Mary's supporters held Edinburgh Castle, MacGill was sent with Robert Pitcairn, Commander of Dunfermline to negotiate with Henry, Lord Hunsdon at Berwick upon Tweed. MacGill was to ask for 8 cannons, 3000 footmen and pikemen, and support for 1000 Scots troops, in the cause of the "maintenance and protection of the true religion to the confusion of those that now goes about to disturb the same". MacGill had a particular interest in the siege as the "registers and records of the chief matters" were guarded by artillery at Edinburgh Castle, together with the Scottish Crown jewels. The forces holding Edinburgh Castle, known as the Castilians, in 1572 twice destroyed MacGill's stronghouses in Edinburgh, and while the siege lasted the Burgh Council met in exile at Leith. Regent Morton wrote to MacGill in 1575 asking him to re-negotiate a gold and silver mining contract with the Dutch engineer Cornelius de Vos. A portrait painter working in Scotland at this time, Arnold Bronckorst, was associated with Cornelius and Nicholas Hilliard. Morton also obtained passports for MacGill's sons, John and David, to travel to France to continue their studies. MacGill died on 16 October 1579. Alexander Hay succeeded him as Lord Clerk Register. His executors were his wife Janet Adamsoun and son, Master James Adamson.
Question: How many years after MacGill accepted appointed as Provot of Edinburgh was he sent to negotiate with Henry?
[EX A]: number

[EX Q]: Passage: By 1759, Alaungpaya had reunified all of Burma plus Manipur and Lan Na. However, his hold on Lan Na and Tenasserim coast was still nominal. The Siamese who originally were concerned about the rising power of Restored Hanthawaddy now actively supported the ethnic Mon rebels operating in the upper Tenasserim coast. In December 1759, Alaungpaya and his 40,000-strong armies invaded the Tenasserim coast. They crossed over the Tenasserim Hills, and finally reached Ayutthaya on 11 April 1760. But only five days into the siege, the Burmese king suddenly fell ill and the Burmese withdrew. The king died three weeks later, ending the war. The 1760 war was inconclusive. Although Burma had regained the upper Tenasserim coast to Tavoy, they still had to deal with Siamese supported rebellions in Lan Na  and at Tavoy . The warfare resumed in August 1765, when two Burmese armies invaded again in a pincer movement on the Siamese capital. The Burmese armies took Ayutthaya in April 1767 after a 14-months' siege. The Burmese armies sacked the city and committed atrocities that mar the Burmese-Thai relations to the present. The Burmese were forced to withdraw a few months later due to the Chinese invasions of their homeland. Burma however had annexed the lower Tenasserim coast.
Question: When did the second seige of Ayutthaya begin?
