instruction:
This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
question:
Passage: Hoping to beat the defending Super Bowl champs, the Ravens returned home. New Orleans struck first with an 18-yard pass from Drew Brees to Jimmy Graham, but Baltimore quickly answered with Flacco throwing a 34-yard pass to Ed Dickson. The Ravens then followed with two touchdowns, both by Ray Rice, one rushing (10&#160;yards) and one passing (17&#160;yards), to bring the score up 21-7. At the close of the half, the Saints scored on a 1-yard pass to Graham to bring the halftime score to 21-14. The Saints kicked a field goal to enter the third quarter to make it 21-17, but the Ravens quickly answered that with a field goal to make it 24-17. The Saints tied it in the fourth quarter on a 15-yard touchdown pass to Lance Moore in the corner of the end zone, a play that was challenged by Baltimore but not overturned. The Ravens managed to get ahead with a Billy Cundiff field goal with 10:03 remaining 27-24.The Saints had the ball in the final minutes backed up near their own end zone when Drew Brees threw an interception to Cory Redding to give Baltimore a chance to run off the clock. Though there was not enough time to run off the entire clock, Baltimore managed to leave just 9&#160;seconds as they kicked a field goal to make it 30-24. The Saints had one last chance on their kickoff return in which they pitched it around in hopes of a touchdown, but they were stopped. They were also called for a moot penalty for a forward pass that would have rendered any drive at this point null. Overall, the game was highlighted by Ray Rice's 153&#160;yards rushing and two touchdowns, Billy Cundiff's two field goals, and the Redding interception that virtually ended the game. With the win, the Ravens went to 10-4, nearly clinching a playoff berth.
answer:
How many first half touchdowns were scored?


question:
Passage: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.
answer:
How many days did the worst terrorist attack and the world's deadliest terrorist attack at sea overlap?


question:
Passage: In 1863, as raids continued between the Navajo and the New Mexican militia, the New Mexico District Military Governor, General James Henry Carleton, told 18 Navajo chiefs that they must surrender by July 20, 1863, and move to Fort Sumner, at the Bosque Redondo. In July, under orders from Gen. Carleton, Col. Kit Carson began a simultaneous campaign against the Mescelaro Apache and Navajo. In a series of raids and skirmishes Carson's troops began rounding up Navajo and Apache and sending them to Bosque Redondo. Between September 1863 and January 1864, Carson and his men chased the Navajo, killing and capturing a few. Crops were burned, stock was confiscated, hogans were burned. Carson attempted to capture a Navajo stronghold in the Battle of Canyon de Chelly. Although the army missed destroying the entire force, they destroyed much Navajo property.
answer:

Across how many months did Carson and his men chase the Navajo?
