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.

Q: Passage: After their road win in Miami, the Patriots returned home to face the Steelers, who the Patriots had not lost to since 2004. On the opening kickoff, Patriots linebacker Vince Redd forced a fumble of Carey Davis at the Steelers' 20-yard line that Davis eventually recovered; an unnecessary roughness penalty by the Steelers' Keyaron Fox meant the Steelers would begin their first drive from their own 10-yard line. Four plays in, Vrabel intercepted Steelers quarterback Ben Roethlisberger and returned it 5 yards to give the Patriots the ball at the Steelers' 14-yard line. After a Welker reception moved the ball to the Steelers' 2-yard line, Morris ran in for a 2-yard touchdown to give the Patriots a 7-0 lead. The Steelers' ensuing possession went three-and-out, but a holding penalty by Aiken on the punt moved the Patriots back to the Steelers' 20-yard line. A 27-yard Moss catch on the next play would help the Patriots reach midfield, but a third-down sack of Cassel set up a Patriots punt, which was returned by the Steelers' Santonio Holmes for 29 yards. Following a 21-yard reception by tight end Heath Miller to begin the drive, the Steelers moved further into Patriots territory on two Nate Washington catches of 15 and 16 yards, both on third down. The Steelers then failed to score from the Patriots' 2-yard line on third down, setting up a 20-yard Jeff Reed field goal to cut the Patriots' lead to 7-3. Three plays into the Patriots' next drive, Moss dropped a pass after he beat his defender inside the Steelers' 35-yard line, eventually setting up another Patriots punt on the final play of the quarter. An exchange of three three-and-outs began the second quarter, leading to Patriots drive that began from their own 40-yard line. A fourth down conversion put the Patriots in the Steelers' red zone, but the Patriots were unable to reach the end zone and settled for a 29-yard Gostkowski field goal that extended their lead to 10-3. Following a 31-yard Gary Russell kick return that gave the Steelers the ball at their own 37-yard line, the Steelers moved 63 yards on 9 plays, capping their drive with a 19-yard Holmes touchdown catch to tie the game at 10 with just under two minutes left in the half. Two plays later, the Patriots found themselves in Steelers' territory again following a 41-yard Faulk run; 35 seconds remained in the first half by the time the Patriots reached the Steelers' 9-yard line on a first down. The Patriots' next three plays would be Cassel pass attempts to Moss; the second of which was dropped by a leaping Moss in the back of the end zone. On fourth down, Gostkowski's 27-yard field goal attempt was no good to keep the game tied at 10 going into halftime. Following a 23-yard defensive pass interference penalty on Steelers cornerback Ike Taylor to begin the second half, the Patriots moved into Steelers' territory, but another sack of Cassel forced a Patriots punt. Starting from their own 14-yard line, the Steelers responded by embarking on a 14-play, 79-drive that reached the Patriots' 7-yard line on a second down but no further; a 25-yard Reed field goal gave the Steelers their first lead of the game, 13-10. With Hobbs, the usual kick returner, on the sidelines vomiting and suffering from cramps, Slater took the ensuing kickoff; the rookie muffed the catch and the fumble was recovered by Fox at the Patriots' 8-yard line. Two plays later, Roethlisberger hit wide receiver Hines Ward for an 11-yard touchdown reception to extend the Steelers' lead to 20-10. Faulk stepped in as kick returner for the next kickoff, which he returned to the Patriots' 29-yard line. However, on the next play, Cassel was strip-sacked by Steelers linebacker James Harrison; the fumble was recovered by linebacker LaMarr Woodley at the Patriots' 26-yard line. Despite a 19-yard Miller catch to begin the Steelers' possession, the Patriots forced the Steelers to kick a field goal; Reed's 20-yard kick gave the Steelers a 23-10 lead. Hobbs came back to return the next kickoff, which began the Patriots' drive from their own 35-yard line. Three plays in, Welker was hit from behind by Steelers safety Ryan Clark after a Cassel pass attempt was tipped; Clark was called for a 15-yard unnecessary roughness penalty to move the Patriots in Steelers' territory. On 3rd-and-11 from the Steelers' 48-yard line, Cassel was again strip-sacked by Harrison; this time linebacker James Farrior recovered the fumble at the Patriots' 47-yard line. The Steelers next drive began on the final play of the third quarter and reached as far as the Patriots' 22-yard line, where Reed missed a 40-yard field goal to give the Patriots the ball back at their own 30-yard line. The Patriots proceeded to move into Steelers' territory, but on 3rd-and-13 from the Steelers' 43-yard line, a Cassel pass intended for Watson was intercepted by safety Troy Polamalu at the Steelers' 11-yard line and returned for 23 yards in the Patriots' fourth turnover of the second half. Three plays later, a 31-yard Willie Parker moved the Steelers to the Patriots' 28-yard line; they would get as far as the Patriots' 22-yard line before Reed kicked a 45-yard field goal to extend the Steelers' lead to 26-10. With less than six minutes remaining in the game, the Patriots began their next series from their own 44-yard line after Reed's kick was returned from the Patriots' 30-yard line. On the first play of the drive, Cassel found Gaffney open inside the Steelers' 25-yard line, but the wide receiver dropped the pass; Taylor threw the ball back toward Gaffney after the play, drawing a 15-yard unsportsmanlike conduct penalty that moved the Patriots into Steelers' territory. Seven plays later, on a first down from the Steelers' 14-yard line, Cassel was intercepted by linebacker Lawrence Timmons, who returned it 89 yards before being tackled at the Patriots' 1-yard line by Watson. Two plays later, Russell ran in for a 1-yard touchdown that gave the Steelers a 33-10 lead with less than three minutes to go in the game. The Patriots could not score on their next possession, ending the game and dropping the Patriots' record to 7-5.

Q: Passage: After their success in the Morea, the Ottomans moved against the Venetian-held Ionian Islands. They occupied the island of Lefkada , which the Venetians had taken in 1684, and the fort of Butrinto opposite the city of Corfu. On 8 July 1716, an Ottoman army of 33,000 men landed on Corfu, the most important of the Ionian islands. Despite an indecisive naval battle on the same day, the Ottoman land army continued its disembarkment and advanced towards the city of Corfu. On 19 July, after capturing the outlying forts of Mantouki, Garitsa, Avrami and of the Saviour, the siege began. The defence was led by Count Johann Matthias von der Schulenburg, who had roughly 8,000 men at his command. The extensive fortifications and the determination of the defenders withstood several assaults. After a great storm on 9 August—which the defenders attributed to the intervention of Corfu's patron saint, Saint Spyridon—caused significant casualties among the besiegers, the siege was broken off on 11 August and the last Ottoman forces withdrew on 20 August.

A: How many days after a great storm was the siege broken off?

Q: Passage: By 2011 fewer than 7% of employees in the private sector belonged to unions. The UAW's numbers of automobile union members are representative of the manufacturing sector: 1,619,000 active members in 1970, 1,446,000 in 1980, 952,000 in 1990, 623,000 in 2004, and 377,000 in 2010 . By 2014, coal mining had largely shifted to open-pit mines in Wyoming, and there were only 60,000 active coal miners.  The UMW has 35,000 members, of whom 20,000 were coal miners, chiefly in underground mines in Kentucky and West Virginia. By contrast it had 800,000 members in the late 1930s. However it remains responsible for pensions and medical benefits for 40,000 retired miners, and for 50,000 spouses and dependents.

A:
How many cities had underground mines?
