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 Dolphins headed to Foxboro to face the Division rival New England Patriots. Little did New England know that they would be a test for an offensive formation concocted as the Dolphins coaching staff wanted to put running backs Ricky Williams and Ronnie Brown onto the field at the same time. David Lee thus revealed the Wildcat to the NFL. Ronnie Brown would take direct snaps and keep it himself or hand it of to another back. The Dolphins decimated the Patriots all day with the Wildcat offense for a 38-13 victory as they put a dent in the Patriots' 21-game regular season winning streak and went on their bye week at 1-2.
[A]: How many points did the Dolphins win by?

[Q]: Passage: In April 1920 Poland launched the large-scale Kiev Offensive in hopes to capture Ukraine. Initially successful, the Polish Army started retreating after Russian counterattacks in early June 1920. Soon the Soviet forces began to threaten Poland's independence as they reached and crossed the Polish borders. On July 9, Polish Prime Minister Wadysaw Grabski asked the Allied Powers in the Spa Conference for military assistance in the war with the Soviets. The conference proposed that the Polish forces would withdraw behind the Curzon Line, the Soviet forces would stop 50km to the east of the line, the Lithuanian forces would take control of Vilnius, and all other disputes would be settled via negotiations in London. Grabski opposed the transfer of Vilnius, but under pressure of British Prime Minister Lloyd George, agreed to the resolution on July 10. At the same time Soviets and Lithuanians negotiated the Soviet-Lithuanian Peace Treaty, which was signed on July 12, 1920. Russia recognized Lithuanian independence and withdrew any territorial claims. The treaty drew the eastern border of Lithuania, which the Lithuanians continued to claim as their de jure state border until World War II. Vilnius Region, including Brasau, Hrodna, Lida, and Vilnius, was recognized to Lithuania. On August 6, after long and heated negotiations, Lithuania and Soviet Russia signed a convention regarding withdrawal of Russian troops from the recognized Lithuanian territory. However, the troops began to retreat only after the Red Army suffered a heavy defeat in Poland.
