TASK DEFINITION: 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.
PROBLEM: Passage: Coming off their commanding road win over the Browns, the Cowboys played their Week 2 home opener under the MNF spotlight.  In the last MNF game at Texas Stadium, Dallas would duel with their NFC East foe, the Philadelphia Eagles.  In the first quarter, the Cowboys trailed early as Eagles kicker David Akers got a 34-yard field goal.  Dallas would answer in their first possession with QB Tony Romo completing a 72-yard TD pass to WR Terrell Owens.  Philadelphia replied with Akers kicking a 44-yard field goal, yet the 'Boys immediately added to their lead with rookie RB Felix Jones returning a kickoff 98 yards for a touchdown. The Eagles would take the lead with QB Donovan McNabb completing a 6-yard TD pass to RB Brian Westbrook, along with LB Chris Gocong recovering a Romo fumble in the Cowboys' endzone for a touchdown.  Dallas immediately responded with Romo and Owens hooking up with each other again on a 4-yard TD pass. On Philadelphia's next drive, the referees made two suspect decisions. The first was a non-call on a very obvious facemask on Brian Westbrook that would have given the Eagles a first down. The next call in question was a 40-yard passing interference penalty on Anthony Henry. Replays showed that it was Greg Lewis who grabbed Henry's jersey and pulled him down, not the other way around. With that decision, the Eagles were awarded a first down on the 1-yard line. Westbrook immediately ran it in for a 1-yard TD. On their next possession, Akers' hit a 22-yard field goal. To make the game the highest scoring half ever on MNF, the Cowboys ended the half with kicker Nick Folk getting a 51-yard field goal, bringing the total points for both teams to 54. In the third quarter, the 'Boys regained the lead with Romo's 17-yard TD pass to RB Marion Barber. In the fourth quarter, the Eagles once again took the lead with Westbrook's 1-yard TD run.  Afterwards, the Cowboys rallied with Folk nailing a 47-yard field goal and Barber getting a 1-yard TD run. The Eagles had a chance for a game-winning drive, but Dallas' defense stiffened for the victory, sacking the very elusive McNabb twice. In a game that had 9 lead changes, it also set different point records, including most first half points in MNF history (54) and most combined points in the rivalry's history (78). Also, Terrell Owens (3 receptions for 89 yards and 2 touchdowns) reached 132 career touchdown catches, placing him 2nd on the NFL's all-time touchdown receptions list (behind only Jerry Rice's record of 197).

SOLUTION: How long were each of Tony Romo's touchdown passes?

PROBLEM: Passage: In week 16, the Lions flew back to Florida, this time to play the Miami Dolphins. The Lions took an early lead with a 39-yard field goal by Dave Rayner. The Dolphins tied it up with a 40-yard field goal by Dan Carpenter. In the second quarter, the Lions took the lead when Brandon Pettigrew caught a 20-yard touchdown pass. The Dolphins tied it up with a 4-yard rush by Lousaka Polite. Miami took the lead with a 13-yard TD catch by Davone Bess. After halftime, the Lions tied it back up with a 5-yard TD rush by Maurice Morris. The Dolphins responded with a 1-yard TD run by Ronnie Brown. Miami added to their lead with a 28-yard field goal. The Lions then scored 17 unanswered points. First Jahvid Best caught a 53-yard TD pass. Then Dave Rayner kicked a 47-yard field goal. They sealed their win when DeAndre Levy intercepted a Chad Henne pass and ran it back 30 yards for a touchdown. With the win not only did the Lions improve to 5-10, but it was their first back-to-back road victories since 2004, and first three-game winning streak since 2007.

SOLUTION: How many TD passes over 50 yards were thrown?

PROBLEM: Passage: The median lethal dose (LD50) for acute radiation exposure is about 4.5 Sievert. The committed effective dose equivalent (CEDE) 210Po is 0.51 µSv/Becquerel if ingested, and 2.5 µSv/Bq if inhaled. So a fatal 4.5 Sv dose can be caused by ingesting , about 50 nanograms (ng), or inhaling , about 10 ng. One gram of 210Po could thus in theory poison 20 million people of whom 10 million would die. The actual toxicity of 210Po is lower than these estimates because radiation exposure that is spread out over several weeks (the biological half-life of polonium in humans is 30 to 50 days) is somewhat less damaging than an instantaneous dose. It has been estimated that a median lethal dose of 210Po is , or 0.089 micrograms, still an extremely small amount. For comparison, one grain of salt is about 0.06 mg  60 μg.

SOLUTION:
How many more micrograms is a median lethal dose of 210Po than a grain of salt?
