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.

Question: Passage: Following a preliminary bombardment, the battle for Cebu City began on March 26, 1945, when the Allies launched Operation Victor II. Staging out of Leyte, where they had conducted rehearsal landings two days earlier, a large flotilla of cruisers and destroyers from the United States Seventh Fleet's Task Force 74 escorted the Cebu Attack Group to the island. Under the leadership of Major General William H. Arnold, the forces assigned to the operation consisted of the Americal Division's 132nd and 182nd Infantry Regiments, totaling about 5,000 men, were landed on Cebu island at Talisay Beach, 4 miles  southwest of Cebu City. The 182nd came ashore southwest of the city, while the 132nd landed at a wide gravel beach to the northeast opposite a palm grove. Meeting no Japanese opposition, the U.S. forces nevertheless suffered heavily from mines and booby traps as they crossed the beach.

Answer: How many infantry regiments did Major General William H. Arnold lead?


Question: Passage: In week two, the Bears donned their 1940s alternate uniforms against rival Minnesota, in the second home game of the season, marking the first time since 1999 that the Bears hosted the first two games of the regular season. During the two games played between the rivals last season, the Bears won the first game 28-10, while the Vikings won the second 21-14. Since 2001, the Bears led the series 16-10. ESPN writes that the Bears could capitalize on the Vikings' tendency to turn the ball over, as they gave away the ball to the Detroit Lions four times in week one. Chicago's defense should also prevent NFL MVP Adrian Peterson, who had been struggling when playing the Bears at Soldier Field. Since 2009, Peterson has been able to record only 73 rushing yards per game. The Bears fell behind early after Cordarrelle Patterson's 105-yard kickoff return for a touchdown. Devin Hester attempted to respond on the ensuing kickoff, but was pushed out of bounds at the Vikings' 32-yard line. The Bears fought back with a one-yard touchdown pass by Jay Cutler to Martellus Bennett, which Chicago added to with Cutler's touchdown pass to Brandon Marshall. In the second quarter, Jared Allen stripped the ball from Cutler, and Brian Robison returned the fumble 61 yards for a touchdown with 7:34 to go in the half. Afterwards, Hester returned the kickoff 80 yards to Minnesota's 23-yard line. The Bears offense later reached Minnesota's one-yard line, but Cutler had his pass intercepted by Kevin Williams in the end zone for a touchback. The Vikings failed to capitalize on the turnover after Tim Jennings intercepted Christian Ponder and scored on a 44-yard interception return. Minnesota retaliated with Ponder's 20-yard touchdown pass to Kyle Rudolph with 1:11 remaining, and the half ended with the Bears settling for a field goal. In the second half, the Vikings scored two field goals from Blair Walsh to take the 30-24 lead. However, the Bears scored on Cutler's 16-yard touchdown pass to Bennett, and ultimately prevailed after recovering a fumbled squib kick. The win marked the second time in franchise history that the Bears won their first two games after trailing in the fourth quarter, the first being in 1971. During halftime, the team honored the 1963 Bears, two days following the death of running back Rick Casares, who was the team's leading rusher until Walter Payton surpassed him. When asked about Casares, defensive end Ed O'Bradovich stated, "Oh my God, I think when you talk to my fellow teammates over here, what was all right, true and good about professional football was embodied in Rick Casares. Nobody loved the game more than him.".

Answer: How many touchdowns did Jay Cutler throw?


Question: Passage: In the early 2000s, Flash was widely installed on desktop computers, and was commonly used to display interactive web pages, online games, and to playback video and audio content. In 2005, YouTube was founded by former PayPal employees, and it used Flash Player as a means to display compressed video content on the web. Between 2000 and 2010, numerous businesses used Flash-based websites to launch new products, or to create interactive company portals. Notable users include Nike, Hewlett-Packard, Nokia, General Electric, World Wildlife Fund, HBO, Cartoon Network, Disney and Motorola. After Adobe introduced hardware-accelerated 3D for Flash , Flash websites saw a growth of 3D content for product demonstrations and virtual tours. In 2007, YouTube offered videos in HTML5 format to support the iPhone and iPad, which did not support Flash Player. After a controversy with Apple, Adobe stopped developing Flash Player for Mobile, focussing its efforts on Adobe AIR applications and HTML5 animation. In 2015, Google introduced Google Swiffy to convert Flash animation to HTML5, a tool Google would use to automatically convert Flash web ads for mobile devices. In 2015, YouTube switched to HTML5 technology on all devices, however it will preserve the Flash-based video player for older web browsers.

Answer:
How many years after YouTube was created did it offer videos in HTML5 format as opposed to Flash only?
