Q: 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: In a game that saw the return of Alex Smith to the Bay Area, the Niners prevailed in a see-saw game, 22-17, on the strength of five Phil Dawson field goals. Kansas City took an early lead on a Smith to Travis Kelce touchdown pass, but Colin Kaepernick hit Stevie Johnson with a TD pass just before halftime for a 13-10 lead. Smith struck again in the third quarter with a 17-yard scoring pass to De'Anthony Thomas, but Dawson hit three more field goals to give the Niners the win. The Niners outgained the Chiefs 357-264, and had a 36:04-23:56 time of possession advantage, but they only scored one touchdown in four trips into the red zone, continuing their season-long problem in that area.
A:
How many less overall yards did the Chiefs have?
