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.
question:
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?
answer:
date


question:
Passage: On the morning of September 11, 2001, nineteen men hijacked four airliners all bound for California. Once the hijackers assumed control of the airliners, they told the passengers that they had a bomb on board and would spare the lives of passengers and crew once their demands were met - no passenger and crew actually suspected that they would use the airliners as suicide weapons since it had never happened before in history, and many previous hijacking attempts had been resolved with the passengers and crew escaping unharmed after obeying the hijackers. The hijackers - members of al-Qaeda's Hamburg cell - intentionally crashed two airliners into the Twin Towers of the World Trade Center in New York City. Both buildings collapsed within two hours from fire damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington County, Virginia, just outside Washington D.C. The fourth plane crashed into a field near Shanksville, Pennsylvania, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington D.C., to target the White House or the U.S. Capitol. None of the flights had any survivors. A total of 2,977 victims and the 19 hijackers perished in the attacks. Fifteen of the nineteen were citizens of Saudi Arabia, and the others were from the United Arab Emirates , Egypt, and Lebanon. On 13 September, for the first time ever, NATO invoked Article 5 of the North Atlantic Treaty. On 18 September 2001, President Bush signed the Authorization for Use of Military Force Against Terrorists passed by Congress a few days prior.
Question: Which happened first, the collapse of the Twin Towers or the plane hitting the Pentagon?
answer:
span


question:
Passage: Dunstable, New Hampshire was a town located in Hillsborough County, New Hampshire. It has been divided into several current cities and towns, including Nashua, Hollis, Hudson, Litchfield, and Merrimack. The town was originally part of a larger town of Dunstable, Massachusetts, when Massachusetts stretched from Rhode Island up to Maine. The original tract of land was bisected by the Merrimack River, an important route for the lucrative fur and log trade. Dunstable was incorporated as a township in 1673. On July 3, 1706, during Queen Anne's War, tribes of the Wabanaki Confederacy raided the town, killing nine while seven of the natives were killed. When the New Hampshire-Massachusetts border was surveyed and adjusted in 1741, the northern part of the town was determined to be in New Hampshire, and was incorporated as a New Hampshire town in 1746. Both the northern New Hampshire half and the southern Massachusetts half prospered, and various villages were formed along the Merrimack, but also along Salmon Brook, the Nashua River, Pennichuck Brook, and the Souhegan River, which also ran through the tract. Over the years, other towns were formed from parts of the original area on both sides of the state line, and in 1836 the remaining part that still bore the name of "Dunstable, New Hampshire" was renamed "Nashua", after the name of the river that flowed into the Merrimack at the location then referred to as "Indian Head". Six years later Nashua split into "Nashville" and "Nashua", but in 1853 they rejoined and became the "City of Nashua". The name Nashville is preserved in the city's Nashville Historic District, and the name Dunstable can still be found in the streets "New Dunstable Road", "Main Dunstable Road", and "East Dunstable Road" .
Question: What name was the area given first, Dunstable or Nashua?
answer:

span
