Given the task definition and input, reply with output. 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.

Passage: On Thanksgiving, the Chiefs played their modern-day rivals, the Denver Broncos. The game was broadcast on the NFL Network as part of the NFL's new "Thanksgiving Tripleheader" tradition, set to kick off the NFL Network's broadcasts of Thursday and Saturday Night Football. The game also aired on Denver and Kansas City local television--KDVR-Fox 31 in Denver and WDAF-Fox 4 in Kansas City at 7pm Kansas City time. The game was broadcast on Westwood One radio. The game marked the first time in NFL history that the league played a triple-header on the holiday, and it was also the first Thanksgiving prime-time game. After John Fogerty played at halftime, the Chiefs showed their own explosive firepower. A big gain by Samie Parker for 31-yards set up another field goal by Lawrence Tynes from 34yards out. The Broncos fought back on their next possession. It appeared the Plummer threw his second interception of the game when Patrick Surtain intercepted a ball intended for Javon Walker, but a penalty on Lenny Walls reversed the call. The Chiefs led 13-10. A defensive battle ensued in the fourth quarter, as the Broncos and Chiefs' defense held each other from scoring again. At the 30-yard line, a pass from Trent Green was intercepted by Darrent Williams, intended for Samie Parker. The Chiefs regained possession at 8:00 left in the game. The Chiefs secured the win The game ball was given to Chiefs founder Lamar Hunt, who lobbied for 37-years to put a Thanksgiving game in Kansas City. The 74-year-old Hunt, who missed only a handful of games since founding the franchise, was admitted to a Dallas-area hospital on Wednesday, bitterly disappointed he would not see Kansas City's inaugurating the NFL's new Thanksgiving tripleheader. Making the night even more festive was an in-house standing-room-only crowd of 80,866, the largest since 1972 (the year Arrowhead Stadium opened).
How many points were the Chief's ahead by at the beginning of the 4th quarter?
