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: Coming off their home win over the Bengals, the Texans flew to the Hubert H. Humphrey Metrodome for a Week 9 interconference duel with the Minnesota Vikings. In the first quarter, Houston trailed early as Vikings RB Adrian Peterson got a 1-yard TD run. The Texans responded with CB Jacques Reeves returning an interception 44 yards for a touchdown. In the second quarter, Minnesota answered with QB Gus Frerotte completing an 8-yard TD pass to WR Sidney Rice and a 49-yard TD pass to WR Bernard Berrian. In the third quarter, Houston tried to rally as QB Sage Rosenfels completed a 3-yard TD pass to WR David Anderson. In the fourth quarter, the Vikings replied with Frerotte completing a 25-yard TD pass to TE Visanthe Shiancoe. The Texans tried to come back as Rosenfels completed a 14-yard TD pass to WR Andre Johnson. However, the Vikings' defense stiffened for the win. QB Matt Schaub (21/29 for 224 yards and 1 interception), who started the game, left after the first half with a sprained left knee.
[EX A]: How many incomplete passes did Matt Schaub throw?

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

[EX Q]: Passage: In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on the Tigris and Euphrates rivers and a canal system for irrigation. Ploughs appear in pictographs around 3,000 BC; seed-ploughs around 2,300 BC. Farmers grew wheat, barley, vegetables such as lentils and onions, and fruits including dates, grapes, and figs. Ancient Egyptian agriculture relied on the Nile River and its seasonal flooding. Farming started in the predynastic period at the end of the Paleolithic, after 10,000 BC. Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. Agriculture in India, wheat, barley, and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle, sheep and goats were domesticated in Mehrgarh by 8,0006,000 BC. Cotton was cultivated by the 5th-4th millennium BC. There is archeological evidence of an animal-drawn plough from 2,500 BC in the Indus Valley Civilization. Agriculture in China, from the 5th century BC there was a nationwide granary system and widespread sericulture. Water-powered grain mills were in use by the 1st century BC, followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron ploughshares and mouldboards. These slowly spread westwards across Eurasia. Asian rice was domesticated 8,20013,500 years ago in China, with a single genetic origin from the wild rice Oryza rufipogon. Agriculture in ancient Greece and Roman agriculture, the major cereals were wheat, emmer, and barley, alongside vegetables including peas, beans, and olives. Sheep and goats were kept mainly for dairy products.
[EX A]:
How many years difference is there between the earliest and latest estimate of when Asian rice was domesticated?
