P: John Graunt noted that in London over a 35-year period in the 17th century (1628–62), the birth sex ratio was 1.07; while Koreas historical records suggest a birth sex ratio of 1.13, based on 5 million births, in 1920s over a 10-year period. Other historical records from Asia too support James hypothesis. For example, Jiang et al. claim that the birth sex ratio in China was 116–121 over a 100-year period in the late 18th and early 19th centuries; in the 120–123 range in the early 20th century; falling to 112 in the 1930s.
Answer this: How many points did London's birth sex ratio differ from Korea's?

A: .06

P: Following two consecutive losses to Dallas and San Diego, Philadelphia went to Chicago to take on the Chicago Bears, who were 4-5, on Sunday Night Football. The Eagles dominated the first quarter as Philadelphia took a two score lead on a 25-yard field goal by David Akers and a 13-yard touchdown from Donovan McNabb to Jason Avant on a wide receiver screen pass. Down 10-0 at the start of the second quarter, Chicago drove within one point as Bears kicker Robbie Gould successfully made a 45-yard field goal, as well as a pair of 28-yard field goals, to make the score 10-9 at the half. In the second half, the Bears took the lead as Robbie Gould kicked his fourth field goal, a 49-yarder that put Chicago up 12-10. However, it took only 30 seconds for the Eagles to take the lead as Donovan McNabb passed to DeSean Jackson for a 48-yard touchdown to give the Eagles a 17-12 lead. Ironically, the 48-yard touchdown catch was the shortest touchdown scored by Jackson thus far in the season. Chicago again took the lead in the third quarter as struggling quarterback Jay Cutler, who had already missed several wide open targets in the game, passed to tight end Kellen Davis for a 15-yard score. The Bears converted the 2-point conversion attempt as running back Matt Forte scored on the pass from Cutler to put the Bears back on top 20-17. In the fourth quarter, both defenses fought back and forth but the only points of the final period were scored by Eagles running back LeSean McCoy on a 10-yard, game-winning touchdown run to put the Eagles up 24-20, the game's final score. With the win, the Eagles improved to 6-4. Ironically, the Eagles win came by the same score (24-20) in the same city (Chicago) at the same time and venue (Sunday Night Football on NBC) as when they had lost in week 4 of the 2008 season.
Answer this: How many yards longer was Robbie Gould's longest field goal of the first half compared to David Aker's only field goal of the first half?
