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: The Oakland Raiders traveled to INVESCO Field at Mile High for Sunday Night Football on October 15. The Raiders arrived in Denver 0-4 while the Broncos began the game tied for first place in their division at 3-1. This game was again primarily a defensive struggle. Oakland had two turnovers deep in Broncos territory, one an interception thrown by Andrew Walter that was picked off by Champ Bailey, and another a fumble by LaMont Jordan. Neither team was able to do much on offense, with just 1 touchdown scored in the entire game (a run by Tatum Bell) and a total of 274 yards produced by the Raiders and 246 yards by Denver. The only turnover of the game by Denver came on a Darrent Williams fumble on a punt return early in the second half. Jason Elam succeeded on kicks from 51 and 22 yards, while Sebastian Janikowski scored the only points for Oakland on a 47-yard field goal in the third quarter. Randy Moss had 86 yards receiving, while Javon Walker had 75 yards. Both had 1 50+ yard catch to put their teams in scoring position. Tatum Bell was the leading rusher with 83 yards. With the win, the Broncos improved to 4-1. The Broncos by this point had only allowed 1 touchdown in 52 opponent possessions. In this game they became the first team since the 1934 Detroit Lions to go five games while allowing only one touchdown to be scored against them.
How many more yards did Randy Moss have than Javon Walker?
