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 Bears entered week 15 of the NFL season hoping to secure a first-round bye and home-field advantage throughout the NFC playoffs. The Bears led 24-3 with 5:22 left in the third quarter and were en route to winning their third straight. During the first quarter, the Bucs had only reached 80 yards in total offense. Coach Jon Gruden sent in back-up Tim Rattay, who completed 20 of 35 for 268 yards with 3 touchdowns and one interception as the Bucs battled back to tie the game up at 31 during the fourth quarter. A controversial move was made by Chicago Bears' head coach Lovie Smith as he decided to let time expire during the fourth quarter and thus send the game into overtime. Tampa Bay won the coin toss, and both teams had three possessions in overtime. After missing earlier in the overtime period, Robbie Gould connected on a 27-yard field goal with 3:37 remaining to give the Bears the victory, 34-31. This loss sent the struggling Buccaneers to 3-11 which secured last place in the NFC South standings.
How many more points did the Bears have at the end than Tampa Bay?

Passage: Hoping to snap their five-game losing streak, the Chiefs went home for a Week 11 interconference duel with the New Orleans Saints.  In the first quarter, Kansas City struck first as QB Tyler Thigpen completed a 6-yard TD pass to WR Dwayne Bowe.  The Saints would respond with kicker Garrett Hartley getting a 30-yard field goal.  In the second quarter, New Orleans took the lead as RB Deuce McAllister got a 1-yard TD run.  The Chiefs would answer with rookie kicker Connor Barth getting a 20-yard field goal.  The Saints closed out the half with Hartley making a 23-yard field goal. In the third quarter, New Orleans increased their lead with QB Drew Brees completing a 47-yard TD pass to WR Lance Moore.  Kansas City replied with Barth making a 21-yard field goal, yet the Saints answered with RB Pierre Thomas getting a 1-yard TD run.  In the fourth quarter, the Chiefs tried to rally as Thigpen hooked up with Bowe again on a 5-yard TD pass.  However, New Orleans pulled away with Hartley nailing a 35-yard field goal.
How long were each of Dwayne Bowe's touchdown receptions?

Passage: In February 1479, a Portuguese army commanded by Garcia de Meneses, Bishop of Évora, penetrated into Extremadura. His objective was to occupy and reinforce the strongholds of Mérida and Medellín, controlled by Beatriz Pacheco, Countess of Medellin and supporter of Afonso V. According to Palencia, the Portuguese army was composed of about 1,000 Knights , plus infantry. 180 Knights of the Order of Santiago marched alongside him, commanded by their treasurer, Alfonso de Monroy. On February 24, near the hill of Albuera, the army was challenged by Isabellian forces commanded by Alonso de Cárdenas, Master of the Order of Santiago. The army consisted of 500 Knights of the Order, 400 Knights of the Hermandad , and 100 infantrymen. The battle was heavily contested. The Isabellian infantry suffered a severe blow from the Juanist cavalry and became disorganized, but intervention by the Master of Santiago aided the panicked infantry. The Portuguese were forced to retreat, leaving significant spoils of war on the battlefield, as well as around 85 dead Knights. Only 15 Isabellian Knights were killed. The bulk of the Portuguese army was able to take refuge in Mérida and from there continued its march to Medellín, which they occupied. Supporters of King Ferdinand placed Medellín and Mérida under siege.

Approximately how many Portuguese knights were killed?
