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.

[Q]: 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?
[A]: span

[Q]: Passage: In November 1656, De Bitter was made Vice-Commandeur, under Commandeur Adriaan Roothaas, of a fleet sent to blockade the Portuguese ports on the coast of Malabar. In the spring of 1657 he returned to Batavia; in August that year he again served under Roothaas on a flotilla blockading Goa. De Bitter's flagship Terschelling captured the Santa Cruz loaded with spices. De Bitter embezzled some of the cargo, for which he would later be lightly punished. The flotilla having been joined by the main force of Colonel Rijcklof van Goens in November, it was decided to split off a large part of the fleet to attack the remaining Portuguese possessions on Ceylon. De Bitter was also used for this expedition, now commanding a larger ship, the Salamander. This ship and the Naarden had the mission to mislead the Portuguese by first sailing to the north and only afterwards rejoin the main force leaving for Ceylon. This ruse failed, however, because adverse winds drove the vessels towards the Maldives. De Bitter only reached Colombo on 17 February 1658, too late to contribute to the capture of Manaar. However he participated in the fall of Jaffnapatnam on 21 June. Again he was used as a messenger to the Council. On 19July 1659, De Bitter, still serving under Roothaas, departed on a fleet of thirteen headed for Goa, on the yacht Tholen. Blockading the port De Bitter confiscated an English vessel, the Constantinople Merchant, on accusations of carrying contraband.
Question: In what years did De Bitter help blockade Goa?
[A]:
