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: Trying to snap a two-game losing streak, the Raiders flew to Qualcomm Stadium for a Week 10 AFC West duel with the San Diego Chargers on Thursday night. Oakland trailed early in the first quarter as Chargers kicker Nick Novak got a 20-yard field goal, yet the Raiders answered with a 2-yard touchdown run from running back Michael Bush. Oakland added onto their lead in the second quarter with a 23-yard field goal from kicker Sebastian Janikowski, followed by quarterback Carson Palmer finding rookie wide receiver Denarius Moore on a 33-yard touchdown pass. San Diego began the third quarter with quarterback Philip Rivers completing a 30-yard touchdown pass to wide receiver Vincent Brown, yet the Raiders struck back with Palmer hooking up with Moore again on a 26-yard touchdown pass. Afterwards, the Chargers closed out the quarter with Rivers completing a 7-yard touchdown pass to fullback Jacob Hester. From there, Oakland's defense held on to preserve the victory. With the win, the Raiders improved to 5-4, and took the lead of the AFC West.

[Q]: 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).
[A]: How many more square miles is San Bernardino County than Kalawao County?

[Q]: Passage: The Russo-Circassian War involved a series of battles and wars in Circassia, the northwestern part of the Caucasus, in the course of the Russian Empire's conquest of the Caucasus. Fighting lasted approximately 101 years, starting in the reign of Empress Catherine the Great and finishing in 1864. Although the Russian conquest of the Caucasus started at least as early as the Russo-Persian Wars, the term Caucasian War commonly refers only to the period 1817-1864. Those who use the term Russian-Circassian War take its starting date as 1763, when the Russians began establishing forts, including at Mozdok, to be used as springboards for conquest. The Caucasian War ended with the signing of loyalty oaths by Circassian leaders on 2 June1864. Afterwards, the Ottoman Empire offered to harbour the Circassians who did not wish to accept the rule of a Christian monarch, and many emigrated to Anatolia, the heart of the Ottoman territory and ended up in modern Turkey, Syria, Jordan, Israel, Iraq and Kosovo. Different smaller numbers ended up in neighbouring Persia. Various Russian, Caucasus, and Western historians agree on the figure of ca. 500,000 inhabitants of the highland Caucasus being deported by Russia in the 1860s. A large fraction of them died in transit from disease. Some of those that remained loyal to Russia were settled into the lowlands, the left-bank of the Kuban River.
