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 most extensive county or county-equivalent is the Yukon-Koyukuk Census Area, Alaska, with a land area of 145,505 square miles (376,856 km2). All nine of the most extensive county-equivalents are in Alaska. The most extensive county is San Bernardino County, California, with a land area of 20,057 square miles (51,947 km2). The least extensive county is Kalawao County, Hawaii, with a land area of 11.991 square miles (31.058 km2). The least extensive county-equivalent in the 50 states is the independent city (United States) Falls Church, Virginia, with a land area of 1.999 square miles (5.177 km2). If U.S. territories are included, the least extensive county-equivalent is Kingman Reef, with a land area of 0.01 square miles (0.03 km2).
How many more square miles is San Bernardino County than Kalawao County?

Passage: In the first period, before 1648, we are dealing mostly with raids and defensive measures. Before 1507 raids were into the Polish Ukraine extending as far as Belarus. After 1507 raiding into the Ukraine continued but most raids were in the region south of Moscow. There was a tendency for population, fortifications and raiding to shift south from Moscow and east from the Polish/Ukrainian area. After 1648 we are dealing with large armies - Tatars, Turks, Poles, Russians and large numbers of Ukrainian Cossacks. Most fighting was in the western Ukraine . This drove the Slavic population to the Left Bank and probably allowed Russian population to expand southward north of Ukraine. Fighting weakened the Polish Commonwealth, but Russia continued to grow southward until it annexed Crimea in 1783. Note that this list does not include raids before 1480, raids further east, most Cossack raids on Crimea and petty raiding between different groups of Nogais, which was considerable. The main underlying theme of the period is the southward expansion of Russian population and the eastward expansion of Ukrainian population. If we had population figures for this the history of the period would be much clearer.
How many years after raids were well into the Polish Ukraine as far as Belarus did Russia annex Crimea?

Passage: The 49ers' 8th match was an Interconference duel with the Broncos at Wembley Stadium. In the first quarter the 49ers took the lead as kicker Joe Nedney got a 34-yard field goal. They soon trailed in the third quarter when QB Tim Tebow scrambled 1 yard for a touchdown; followed in the fourth quarter by kicker Matt Prater hitting a 32-yard field goal. They soon went on a scoring rally to take the lead with QB Troy Smith scrambling a yard for a touchdown, followed by his 28-yard TD pass to WR Michael Crabtree. Then RB Frank Gore got a 3-yard TD run to put the 49ers up 24-10. The lead was narrowed when QB Kyle Orton made a 1-yard TD pass to WR Brandon Lloyd (with a failed PAT). With the win, the 49ers went into their bye week at 2-6.

How long were each of the field goals in the game?
