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.

[EX Q]: Passage: Persia attempted to ratify the Treaty of Constantinople , by demanding that the Ja'fari, also known as the Imamiyyah was to be accepted as a fifth legal sect of Islam. In 1743, Nader Shah declared war on the Ottoman Empire. He demanded the surrender of Baghdad. The Persians had captured Baghdad in 1623 and Mosul in 1624, but the Ottomans had recaptured Mosul in 1625 and Bagdad in 1638. The Treaty of Zuhab in 1639 between the Ottoman Empire and the Safavid Empire had resulted in peace for 85 years. After the fall of the Safavid Dynasty, Russia and the Ottoman Empire agreed to divide the northwest and the Caspian region of Persia, but with the advent of Nader Shah, the Russians and the Turks withdrew from the region. Nader Shah waged war against the Ottomans from 1730 to 1736 but it ended with a stalemate. Nader Shah afterwards turned east and declared war on the Moghul Empire and invaded India, in order to refund his wars against the Ottomans.
Question: How many years did Nader Shah wage war against the Ottomans?

[EX Q]: Passage: Coming off their home win over the Raiders, the Texans flew to the University of Phoenix Stadium for the first time ever for a Week 5 interconference duel with the Arizona Cardinals.  Houston would trail in the first quarter as Cardinals running back Tim Hightower got a 1-yard touchdown run in the first quarter, followed by quarterback Kurt Warner completing a 9-yard and a 26-yard touchdown pass to wide receiver Larry Fitzgerald.  Afterwards, the Texans began to rally as running back Chris Brown got a 1-yard touchdown run in the third quarter.  Then, quarterback Matt Schaub would hook up with wide receiver Andre Johnson on an 11-yard and a 17-yard touchdown pass in the fourth quarter.  However, Arizona would strike on two key plays.  First, Cardinals cornerback Dominique Rodgers-Cromartie would intercept a pass from Schaub and return it 49 yards.  Second, Arizona's defense held Houston's offense 1 yard out of the endzone three times.
Question: how many yards did hightower get?

[EX Q]: Passage: Upon becoming commercial station WCBW  in 1941, the pioneer CBS television station in New York City broadcast two daily news programs, at 2:30 and 7:30 p.m. weekdays, anchored by Richard Hubbell. Most of the newscasts featured Hubbell reading a script with only occasional cutaways to a map or still photograph. When Pearl Harbor was bombed on December 7, 1941, WCBW , took to the air at 8:45 p.m. with an extensive special report. The national emergency even broke down the unspoken wall between CBS radio and television. WCBW executives convinced radio announcers and experts such as George Fielding Elliot and Linton Wells to come down to the Grand Central studios during the evening and give information and commentary on the attack. The WCBW special report that night lasted less than 90 minutes. But that special broadcast pushed the limits of live television in 1941 and opened up new possibilities for future broadcasts. As CBS wrote in a special report to the FCC, the unscheduled live news broadcast on December 7 "was unquestionably the most stimulating challenge and marked the greatest advance of any single problem faced up to that time." Additional newscasts were scheduled in the early days of the war. In May 1942, WCBW  sharply cut back its live program schedule and the newscasts were canceled, since the station temporarily suspended studio operations, resorting exclusively to the occasional broadcast of films. This was primarily because much of the staff had either joined the service or were redeployed to war related technical research, and to prolong the life of the early, unstable cameras which were now impossible to repair due to the wartime lack of parts.
Question: Why was there a special report on WCBW on December 7, 1941?
