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: 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?

Output: span


Input: Consider Input: Passage: The 49ers' 8th match was an Interconference duel with the Broncos at Wembley Stadium. In the first quarter the 49ers took the lead as kicker Joe Nedney got a 34-yard field goal.

Input: Consider Input: Passage: For about three centuries, the Qing dynasty had enforced—albeit with mixed success—a policy of segregating the non-Han peoples  on the frontier from Han Chinese. By the end of the 19th century, however, China faced the prospect of being parcelled out among the Western powers and Japan, each competing for its own sphere of influence in the country. On the northern frontier, Russian Empire was viewed by the Qing court as posing the greatest threat to its territorial integrity. In response, the Qing government adopted a different policy, the "New Administration" or "New Policies" , which called for the sinification of Mongolia through Chinese colonisation, the exploitation of Mongolia's natural resources , military training, and education. Many Mongols regarded the "New Policies" as a major threat to their traditional way of life, as was agreed to be preserved when they recognised authority of the Qing emperors, and began to seek independence. In July 1911 a group of Khalkha nobles persuaded the Jebtsundamba Khutuktu, the head of Mongolian Buddhism , that Mongolia must declare its independence from the Qing dynasty. They agreed to send a small delegation to Russia to obtain its assistance in this undertaking. In October 1911 revolution broke out in China, with one province after another declaring its independence from the Qing government. On 1 December 1911 Outer Mongolia declared independence, and established a theocracy under the Khutuktu. On 29 December he was installed as the Bogd Khaan  of Mongolia. This ushered in the Bogd Khaan era, which lasted from 1911 to 1919.
Question: How many months after revolution broke out in China did Outer Mongolia declare independence?
