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.

Other 67s were scored in the 1980s, 1990s and 2010s. His most recent 67 at Augusta was his opening round in 2010. His US Open low score is a 65. He scored 65 in 1987 and 2003, 66 in 1993 and he first shot 67 in 1975. At the British Open, Watsons low score is a 64 in 1980. 65s were scored in 1977 (twice), 1994 and 2009 (all 65s at the Open were scored at Turnberry). Finally at the PGA Championship, Watsons low score of the 1970s was a 66 in 1979. In the 1980s he scored a 67 in 1980, 1983, 1985, and 1989. His low PGA score is a 65 in 1993 & 2000.

Q: Passage: In Caleb Hanie's first NFL start, he threw three interceptions in the first half, but was able to rally by completing 18 of 36 passes for 254 yards, two touchdowns and a 56.9 passer rating. However, Raiders kicker Sebastian Janikowski's six field goals would put the game away. Late in the fourth quarter, with the Bears down 25-20, Hanie attempted to rally the Bears from their own 4-yard line. When the Bears reached their own 46-yard line with less than ten seconds in the game, Hanie dropped back and looked around as if he was going to throw before spiking, drawing an intentional grounding penalty. Since intentional grounding penalties have a ten-second runoff, the game ended in defeat for Chicago.

A:
How many points did the Raiders win by?
