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: AH-1 Cobras were in use by the Army during the Tet offensive in 1968 and through to the end of the Vietnam War. Cobras provided fire support for ground forces, escorted transport helicopters and other roles, including aerial rocket artillery (ARA) battalions in the two Airmobile divisions. They also formed "hunter killer" teams by pairing with OH-6 Cayuse scout helicopters. A team featured one OH-6 flying slow and low to find enemy forces. If the OH-6 drew fire, the Cobra could strike at the then revealed enemy. On 12 September 1968, Capt. Ronald Fogleman was flying an F-100 Super Sabre when the aircraft was shot down and he ejected 200 miles north of Bien Hoa.  Fogleman became the only pilot to be rescued by holding on to an Army AH-1Gs deployed gun-panel door. Bell built 1,116 AH-1Gs for the U.S. Army between 1967 and 1973, and the Cobras chalked up over a million operational hours in Vietnam; the number of Cobras in service peaked at 1,081. Out of nearly 1,110 AH-1s delivered from 1967 to 1973 approximately 300 were lost to combat and accidents during the war.  The U.S. Marine Corps used AH-1G Cobras in Vietnam for a short time before acquiring twin-engine Bell AH-1 SuperCobra.
[EX A]: Approximately how many of the 1110 AH-1s delivered from 1967 to 1973 were lost per year on average?

[EX Q]: Passage: The Jets' seventh game was an interconference duel with the Packers. Punter Steve Weatherford made the game's most controversial decision in the first quarter, opting to attempt a fake punt and run for the first down on 4th and 18. Weatherford was stopped a yard short of the first down, giving the Packers ideal field position which eventually led to an early 3-0 Packers lead. "He does it on his own," Ryan said. "(The Packers) were caving that side down. This was something Steve did on his own. I don't think he realized we'd just been sacked. We told him before that it needed to be a manageable situation, not fourth-and-20 or whatever it was.". In a game where defense ruled, the Packers lead 3-0 at halftime.  The Jets challenged a Brad Smith fumble, and lost due to his knee not being down before losing the ball.  However, the Jets second challenge went to a jump ball, called an interception after Packers cornerback Tramon Williams ripped the ball out of Jerricho Cotchery's hands while they were both on the ground.  The play was controversially upheld, despite the fact that the receiver appeared to be down by contact.  With no challenges left, Mark Sanchez threw a ball to Dustin Keller that was ripped out of his hands and ruled an interception in the 4th quarter. The replay showed that Keller made the catch and was also down before losing possession, but with no challenges left the Jets were left with nothing. Green Bay took a 6-0 lead after the turnover. The Jets had two more chances to take the lead but had drives halted on 4th and longs. The Packers added on another field goal late to finalize a 9-0 win in the New Meadowlands Stadium. This marked the first time since 2006 the Jets were shut out.
[EX A]: How many interceptions did the Jets throw?

On the night of 3 to 4 January 1684 the Moldavian allies betrayed the Cossacks and left the Cossack camp. In this situation Kunitsky with the Cossack cavalry  broke through the enemy ring and crossed the Prut. The Cossack infantry  under Andrey Mogila also broke out and crossed the Prut near Boyanova, but suffered heavy losses. By 10 January only five thousand Cossacks reached Jassy.
