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.

Passage: The Ravens were facing the Tampa Bay Buccaneers, a team with an identical 7-3 record. However, the Ravens were considered favorites going into the game, given that they had never lost at home during the season, and all Tampa Bay wins were against teams with losing records. Still, they did not take this one lightly. After a scoreless first quarter, the Ravens scored first with a field goal. Tampa Bay later tied it, but Baltimore scored two touchdowns, including one on a 65-yard pass from Todd Heap, to have a 17-3 halftime lead. During a scoreless third quarter, a would be long TD-run from Ray Rice was negated by a controversial call of a penalty on Anquan Boldin. Though the Ravens would never score anymore in the game, they managed to hold off Tampa Bay and allow just one touchdown, enough to prevent their lead from being blown.
How long was Todd Heaps touchdown?

Passage: On 26 August 1643, during the minority of the former chief, "the Estates of the Kingdom passed an Act for the Committees of War in the shires of Scotland", and among the Commissioners for the Sheriffdom of Sutherland and a par of Inverness-shire, occurs the name of "Sir Robert Munro, tutour of Foulles"; and again on 24 July 1644, in a commission for a similar purpose and for the same Sheriffdom is found the name of "Sir Robert Monro, Tutor of Foullis". In 1649, the Scottish Parliament separated from the Sherriffdom of Inverness-shire the "lands eastward of Altnalait, Knockravock and the Royal Burgh of Tain", erected the Sherriffdom of Ross, and appointed the Marquiss of Argyll the Sherriff-Principal. Afterwards the commission was granted to Sir Robert Munro, who had been elected Member of Parliament for Inverness-shire in 1649 and for his own County of Ross after it was separated from the County of Inverness, 1649-50, to be Sheriff-Principal of the County of Ross. In 1651 Robert succeeded to the head of his house, upon the death of his cousin Sir Hector Munro, 2nd Baronet of Foulis who died at just 17 years of age, as already mentioned. Robert took up his residence in Foulis Castle.
How many days apart did the name "Sir Robert Munro, tutour of Foulles" occur in a commission?

Passage: By this time Hu Zongxian had almost collected his strength: Lu Tang had won a decisive victory in Taizhou south of Ningbo and came back to help deal with Xu Hai; while 6000 fresh aboriginal soldiers from Baojing and Yongshun were on its way to come to Hu Zongxian's aid. The imperial inspector Zhao Wenhua reiterated the emperor's wishes that surrender was not an option, so Hu Zongxian made a show of receiving Xu Hai's surrender while waiting for the opportune moment to strike. In the meantime Xu Hai had settled in the Shen Family Estate  of Pinghu, where he recruited up to 300 new followers by hosting banquets for his neighbours, adding to the thousand or more raiders still under his command and remnants of Chen Dong's group next to the estate. He grew increasingly recalcitrant, refusing an invitation to an official Mid-Autumn party and even killing an envoy from Hu Zongxian. In late September, reinforcements from Baojing and Yongshun arrived and began small-scale skirmishes around the Shen Family Estate. Before commencing the final attack, Hu Zongxian persuaded his captive Chen Dong to write a letter to his followers encamped next to Xu Hai's forces, warning them that Xu Hai was conspiring with government troops to wipe them out in a pincer operation. This provoked Chen Dong's men into attacking Xu Hai's group on September 27, upon which government forces entered the fray from all directions, killing indiscriminately. On September 29, the battle ended with up to 1600 marauders killed in the estate, and Xu Hai's body was found in a nearby stream. On October 10, Chen Dong, Ye Ma, and Xu Hai's hostage brother were all executed in Jiaxing, marking the end of the wokou invasion of 1556.

After Chen Dong's men turned on Xu Hai, how many days did the battle last?
