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: Coming off of their dominant home win over the Steelers, the Ravens flew to Paul Brown Stadium for an AFC North rematch with the Cincinnati Bengals, trying to win the division and a playoff berth on this Thursday Night fight.  After a scoreless first quarter, the Ravens trailed early as Bengals kicker Shayne Graham kicked a 23-yard and a 27-yard field goal.  In the third quarter, things went from bad to worse for Baltimore as QB Carson Palmer completed a 40-yard flea-flicker TD pass to WR T. J. Houshmandzadeh for the only score of the period.  In the fourth quarter, the Ravens valiantly tried to fight back, as QB Steve McNair completed a 36-yard TD pass to WR Derrick Mason.  However, a failed onside kick spelled Baltimore's doom.  With the loss, the Ravens fell to 9-3.
Question: How many wins did the Ravens have after this game?

Example Input: Passage: In July 1449 Esen Tayisi  of the Mongols launched a large-scale, three-pronged invasion of China with his puppet khagan Toqtaq-Buqa. He personally advanced on Datong  in August. The eunuch official Wang Zhen, who dominated the Ming court, encouraged the 22-year-old Zhengtong Emperor to lead his own armies into battle against Esen. The size of Esen's army is unknown but a best guess puts it at some 20,000 men. The Ming army of about 500,000 was hastily assembled; its command was made up of 20 experienced generals and a large entourage of high-ranking civil officials, with Wang Zhen acting as field marshal. On August 3 Esen's army crushed a badly supplied Chinese army at Yanghe, just inside the Great Wall. The same day the Emperor appointed his half-brother Zhu Qiyu as regent. The next day he left Beijing for Juyong Pass. The objective was a short, sharp march west to Datong via the Xuanfu garrison, a campaign into the steppe and then a return to Beijing by a southerly route through Yuzhou. Initially the march was mired by heavy rain. At Juyong Pass the civil officials and generals wanted to halt and send the emperor back to Beijing, but their opinions were overruled by Wang Zhen. On August 16, the army came upon the corpse-strewn battlefield of Yanghe. When it reached Datong on August 18, reports from garrison commanders persuaded Wang Zhen that a campaign into the steppe would be too dangerous. The "expedition" was declared to have reached a victorious conclusion and on August 20 the army set out back toward China proper.
Question: When was the Zhengtong Emperor born?
Example Output: date

Example Input: Passage: The 767 has been involved in six hijackings, three resulting in loss of life, for a combined total of 282 occupant fatalities. On November 23, 1996, Ethiopian Airlines Flight 961, a 767-200ER, was hijacked and crash-landed in the Indian Ocean near the Comoros Islands after running out of fuel, killing 125 out of the 175 persons on board; survivors have been rare among instances of land-based aircraft ditching on water. Two 767s were involved in the September 11 attacks on the World Trade Center (1973-2001) in 2001, resulting in the Collapse of the World Trade Center. American Airlines Flight 11, a 767-200ER, crashed into the North Tower, killing all 92 people on board, and United Airlines Flight 175, a 767-200, crashed into the South Tower, with the death of all 65 on board. In addition, more than 2,600 people were killed in the towers or on the ground. A foiled 2001 shoe bomb plot involving an American Airlines 767-300ER resulted in passengers being required to remove their shoes for scanning at US security checkpoints.
Question: Which 767 airplane has the least amount of deaths during a hijacking, Ethiopian Airlines Flight 961 or United Airlines Flight 175?
