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: The Jurchens were a Tungusic-speaking group of semi-agrarian tribes inhabiting areas of northeast Asia that are now part of Northeast China. Many of the Jurchen tribes were vassals of the Liao dynasty , an empire ruled by the nomadic Khitans that included most of modern Mongolia, a portion of North China, Northeast China, northern Korea, and parts of the Russian Far East. To the south of the Liao lay the Han Chinese Song Empire . The Song and Liao were at peace, but since a military defeat to the Liao in 1005, the Song paid its northern neighbor an annual indemnity of 200,000 bolts of silk and 100,000 ounces of silver. In 1114, the chieftain Wanyan Aguda  united the disparate Jurchen tribes and led a revolt against the Liao. In 1115 he named himself emperor of the Jin "golden" dynasty . Informed by a Liao defector of the success of the Jurchen uprising, the Song emperor Huizong  and his highest military commander the eunuch Tong Guan saw the Liao weakness as an opportunity to recover the Sixteen Prefectures, a line of fortified cities and passes that the Liao had annexed from the Shatuo Turk Later Jin in 938, and that the Song had repeatedly but unsuccessfully tried to reconquer. The Song thus sought an alliance with the Jin against their common enemy the Liao.

A: How many areas did the Khitans rule over?

Q: Passage: Three star systems appear to have exoplanet. HD 9446 is a sun-like star around 171 light-years distant that has two planets of masses 0.7 and 1.8 times that of Jupiter, with orbital periods of 30 and 193 days respectively. WASP-56 is a sun-like star of spectral type G6 and apparent magnitude 11.48 with a planet 0.6 the mass of Jupiter that has a period of 4.6 days. HD 13189 is an orange giant of spectral type K2II about 2-7 times as massive as the sun with a planetary or brown dwarf companion between 8 and 20 times as massive as Jupiter, which takes 472 days to complete an orbit. It is one of the largest stars discovered to have a planetary companion.

A: How many of HD 9446's planetary companions are larger than Jupiter?

Q: Passage: Trying to snap a two-game losing streak, the Ravens flew to the Hubert H. Humphrey Metrodome for a Week 6 interconference duel with the Minnesota Vikings.  Baltimore would trail in the first quarter as Vikings quarterback Brett Favre completed a 19-yard touchdown pass to tight end Visanthe Shiancoe and a 4-yard touchdown pass to wide receiver Bernard Berrian.  Afterwards, the Ravens would snag the only points of the second quarter with kicker Steven Hauschka making a 29-yard field goal. In the third quarter, Minnesota would extend its lead as kicker Ryan Longwell nailed a 40-yard field goal. Baltimore would come right back into the game with running back Ray Rice's 22-yard touchdown run, but Longwell helped out the Vikings with a 22-yard field goal.  In a nerve-racking fourth quarter, Minnesota increased its lead with Favre finding Shiancoe again on a 1-yard touchdown run.  The Ravens would respond with quarterback Joe Flacco's 32-yard touchdown pass to wide receiver Mark Clayton.  After Longwell gave the Vikings a 29-yard field goal, Baltimore would take the lead as Flacco completed a 12-yard touchdown pass to wide receiver Derrick Mason and Rice getting a 33-yard touchdown run.  Minnesota would regain the lead as Longwell booted a 31-yard field goal.  Flacco would get the Ravens into scoring range, but Hauschka's 44-yard field goal attempt sailed wide left, preserving the Vikings' so-far perfect season. With the loss, Baltimore went into its bye week at 3-3. This also marked the first time that the Ravens defense allowed back-to-back 100-yard rushers since 2005 (Bengals' Rudi Johnson & Texans' Domanick Williams).

A:
How many field goals of at least 40 yards were made?
