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.

[EX Q]: Passage: Spanish Town is the site of an early cast-iron bridge, designed by Thomas Wilson and manufactured by Walker and Company of Rotherham, England. Spanning the Rio Cobre, the bridge was erected in 1801 at a cost of £4,000. Its four arched ribs are supported on massive masonry abutments. After the abutments deteriorated, endangering the structure, it was listed in the 1998 World Monuments Watch by the World Monuments Fund. A restoration project began in 2004, with funding provided by American Express through World Monuments Fund. Progress was slow until 2008, when a renewed restoration effort was made. A first phase of restoration was completed in April 2010, when the repair of the abutments allowed the bridge to be reopened for the public. More recently, violence in the area has prevented the bridge from achieving the status of a UNESCO World Heritage Site.
[EX A]: How many years after being built was it before the bridge restoration began?

[EX Q]: Passage: The Dolphins began their 2007 campaign on the road against the Washington Redskins. After a scoreless first quarter, the Redskins made the first move with kicker Shaun Suisham getting a 31-yard field goal three minutes into the second quarter. Miami took the lead before the end of the half with a one-yard touchdown pass from Trent Green to tight end Justin Peelle as time expired. Washington took a 10-7 lead on a 19-yard Clinton Portis touchdown run with just under 12 minutes remaining in the third quarter.  Dolphins kicker Jay Feely tied the game at 10 later in the quarter on a 20-yard field goal, and each team notched another field goal in the fourth quarter. With four seconds remaining and the ball on the Washington 43-yard line, Redskins quarterback Jason Campbell launched a last-second Hail Mary pass that was batted by Dolphins defensive end Jason Taylor in the end zone. Redskins wide receiver Antwaan Randle El caught the ball at the six but was tackled at the three-yard line before he could score the winning touchdown. The Redskins won the coin toss to begin overtime and promptly mounted a 10-play, 62-yard drive that included just two passes. Suisham made his third field goal of the game, this time from 39 yards out, to win the game 16-13 and hand Miami their first loss of the season as they started out 0-1 and 0-1 against NFC Opponents.
[EX A]: How many field goals did both teams score in the fourth quarter?

[EX Q]: Passage: The Lithuanian Civil War of 1432-1438 was a conflict over the succession to the throne of the Grand Duchy of Lithuania, after Vytautas the Great died in 1430 without leaving an heir.  The war was fought on the one side by Švitrigaila, allied with the Teutonic Knights, and on the other by Sigismund Kęstutaitis, backed by the Kingdom of Poland. The war threatened to sever the Union of Krewo, the personal union between Poland and Lithuania. Švitrigaila's alliance with the Grand Master of the Teutonic Order, Paul von Rusdorf, launched the Polish-Teutonic War  but failed to secure victory for Švitrigaila. When Sigismund captured power in Lithuania by staging a coup in 1432, Lithuania split into two opposing camps, and there began three years of devastating hostilities. To prevent the Knights from continuing their support of Švitrigaila, Poland backed a Hussite invasion of Prussia in 1433. The war ended in a decisive defeat for Švitrigaila and his ally, the Livonian branch of the Teutonic Knights, at the Battle of Pabaiskas in September 1435. Švitrigaila eventually surrendered in 1437; Sigismund Kęstutaitis ruled Lithuania for only eight years before he was assassinated in 1440.
[EX A]:
How many years after Vytautas the Great died did the Lithuanian Civil War start?
