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.

Example 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?
Example Output: span

Example Input: Passage: On 15 August 1919, German border guards  massacred ten Silesian civilians in a labour dispute at the Mysłowice mine . The massacre sparked protests from the Silesian Polish miners, including a general strike of about 140,000 workers, and caused the First Silesian Uprising against German control of Upper Silesia. The miners demanded the local government and police become ethnically mixed to include both Germans and Poles. About 21,000 Germans soldiers of the Weimar Republic's Provisional National Army , with about 40,000 troops held in reserve, quickly put down the uprising. The army's reaction was harsh; and about 2,500 Poles were either hanged or executed by firing squad for their parts in the violence. Some 9,000 ethnic Poles sought refuge in the Second Polish Republic, taking along their family members. This came to an end when Allied forces were brought in to restore order, and the refugees were allowed to return later that year.
Question: What year were Polish refugees allowed to return after the First Silesian Uprising?
Example Output:
date
