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: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.

SOLUTION: How many months did it take them to build The Lines of Communication?

PROBLEM: Passage: In the second meeting of the year with the Washington Redskins, the Eagles tried an onside kick to start the game. This backfired when the Redskins running back Quinton Ganther recovered the kick and returned it 25 yards to the Eagles 24-yard line. Four plays later, Redskins quarterback Jason Campbell ran for a two-yard touchdown to score the game's first touchdown, as the Redskins took the lead 7-0. After a holding penalty on Eagles tight end Brent Celek, the Eagles had to settle for a 29-yard field goal by kicker David Akers. On the following drive by the Eagles, quarterback Donovan McNabb found wide receiver DeSean Jackson wide open in the end zone for a 35-yard touchdown to bring the Eagles up 10-7. On the ensuing drive by the Redskins, Campbell threw a 4-yard touchdown pass to Santana Moss to take the lead 14-10. Late in the second quarter, after both teams punting the ball away after three unsuccessful drives, Eagles cornerback Asante Samuel intercepted a Jason Campbell pass that was intended for Santana Moss. The Eagles could not convert a third down with 10 to go, and David Akers kicked a 24-yard field goal to get the Eagles within a point of the Redskins, 14-13. The Redskins received the ball again and Campbell threw a second straight interception to Samuel, who returned it for 17 yards. The Eagles ended the first half with a second straight field goal to take the lead 16-14. The Eagles got the ball to start the second half, but the drive ended with a Sav Rocca punt. Jason Campbell threw a 10-yard touchdown to tight end Fred Davis to take the lead once again, 21-16. After two straight punts for each team, the Eagles got the ball back in the fourth quarter and Donovan McNabb threw an intended pass to Reggie Brown, but the pass was intercepted by Redskins cornerback Justin Tryon. The Redskins scored on a 25-yard field goal by Shaun Suisham, to increase their lead 24-16. The Eagles started their drive on their own 10-yard line after a penalty on the kick return by Dimitri Patterson. The Eagles went 90 yards to score on an Eldra Buckley one-yard touchdown run. Since they were losing by two points, the Eagles decided to go for a two-point conversion. The two-point conversion was successful after rookie running back LeSean McCoy ran in the end zone on a shovel pass from McNabb. The score was tied, 24-24. The Redskins could not score on the next drive, and therefore had to punt to the Eagles. The Eagles scored on a 32-yard field goal by David Akers to take the lead, 27-24. The Eagles got the ball back on downs, and kneeled the ball to run out the clock and win 27-24.

SOLUTION: How many field goals were kicked in the game?

PROBLEM: Passage: The Black Sea Fleet  is the fleet of the Russian Navy in the Black Sea, the Sea of Azov and the Mediterranean Sea. The fleet is considered to have been founded by Prince Potemkin on May 13, 1783. In 1918, the fleet was inherited by the Russian SFSR then the Soviet Union in 1922, where it became part of the Soviet Navy. Following the collapse of the Soviet Union in 1991, the Black Sea Fleet and most of its vessels were inherited by the Russian Federation. The Black Sea Fleet's official primary headquarters and facilities are located in the city of Sevastopol, which is de jure part of Ukraine but de facto part of Russia . The remainder of the fleet's facilities are based in various locations on the Black Sea and the Sea of Azov, including Krasnodar Krai, Rostov Oblast and Crimea. The current commander is Admiral Aleksandr Viktorovich Vitko, who has held the position since April 2013.

SOLUTION:
How many seas does the Black Sea Fleet reside in?
