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: Coming off their dominating road win over the Jaguars, the Eagles went home for their Week 4 NFC East duel with the Washington Redskins, as quarterback Donovan McNabb made his highly anticipated return to Philadelphia. The Eagles trailed in the first quarter as Redskins running back Ryan Torain got a 12-yard touchdown run, followed by McNabb's 31-yard touchdown pass to tight end Chris Cooley.  Philadelphia answered in the second quarter with kicker David Akers making a 49-yard field goal, but Washington came right back with kicker Graham Gano's 26-yard field goal.  Afterwards, the Eagles closed out the half with Akers' 23-yard field goal.  After a scoreless third quarter, Philadelphia tried to rally in the fourth quarter as quarterback Kevin Kolb hooked up with tight end Brent Celek.  However, the Redskins' defense prevented any further progress.
answer:
How many field goals did Akers make?


question:
Passage: The Broncos' defense forced a three-and-out on the Patriots' first offensive drive, however, it was all downhill for the Broncos after that. The Patriots capitalized on four blunders by the Broncos' special teams. First, Isaiah McKenzie muffed a punt, giving the Patriots a short field. Then, Patriots' return specialist Dion Lewis returned a kickoff 103 yards for a touchdown. The Patriots also blocked a punt, and a defensive penalty on a Patriots' punt resulted in a first down as well as another touchdown. Patriots' quarterback Tom Brady threw for 266 yards and three touchdown passes. Offensively, the Broncos had to settle for three Brandon McManus field goals and achieved only one touchdown &#8212; a 7-yard pass from Brock Osweiler to wide receiver Demaryius Thomas.
answer:
How many touchdowns did the Broncos score?


question:
Passage: By 1208, the Germans were strong enough to begin operations against the Estonians, who were at that time divided into eight major and several smaller counties led by elders with limited co-operation between them. In 1208-27, war parties of the different sides rampaged through the Livonian, Northern Latgallian, and Estonian counties, with Livonians and Latgallians normally as allies of the Crusaders, and the Principalities of Polotsk and Pskov appearing as allies of different sides at different times. Hill forts, which were the key centres of Estonian counties, were besieged and captured a number of times. A truce between the war-weary sides was established for three years  and proved generally more favourable to the Germans, who consolidated their political position, while the Estonians were unable to develop their system of loose alliances into a centralised state. The Livonian leader Kaupo was killed in battle near Viljandi  on 21 September 1217, but the battle was a crushing defeat for the Estonians, whose leader Lembitu was also killed. Since 1211, his name had come to the attention of the German chroniclers as a notable Estonian elder, and he had become the central figure of the Estonian resistance. The Christian kingdoms of Denmark and Sweden were also greedy for conquests on the Eastern shores of the Baltic. While the Swedes made only one failed foray into western Estonia in 1220, the Danish Fleet headed by King Valdemar II of Denmark had landed at the Estonian town of Lindanisse  in 1219. After the Battle of Lyndanisse the Danes established a fortress, which was besieged by Estonians in 1220 and 1223, but held out. Eventually, the whole of northern Estonia came under Danish control.
answer:

How many times did the Estonians besiege a fortress established by the Danes?
