Q: Passage: The exact origin of the 260-day count is not known, but there are several theories. One theory is that the calendar came from mathematical operations based on the numbers thirteen and twenty, which were important numbers to the Maya. The numbers multiplied together equal 260. Another theory is that the 260-day period came from the length of human pregnancy. This is close to the average number of days between the first missed menstrual period and birth, unlike Naegele's rule which is 40 weeks  between the last menstrual period and birth. It is postulated that midwives originally developed the calendar to predict babies' expected birth dates. A third theory comes from understanding of astronomy, geography and paleontology.  The mesoamerican calendar probably originated with the Olmecs, and a settlement existed at Izapa, in southeast Chiapas Mexico, before 1200 BCE. There, at a latitude of about 15° N, the Sun passes through zenith twice a year, and there are 260 days between zenithal passages, and gnomons , were found at this and other sites. The sacred almanac may well have been set in motion on August 13, 1359 BCE, in Izapa.

Q: Passage: Week 10 featured the top-ranked defenses (by yardage against) in each conference, as the Lions hosted the Dolphins. Detroit got off to a quick start. Matt Prater kicked a 26-yard field goal on the opening drive of the game. Later in the first quarter, Calvin Johnson, playing in his first game since Week 5, caught a 49-yard TD pass from Matthew Stafford for a 10-0 lead. Miami managed a 23-yard Caleb Sturgis field goal before halftime, making the score 10-3. The Dolphins took the lead in the third, starting with a 50-yard Stugis field goal. Next, Earl Mitchell blocked Prater's 42-yard field goal attempt, and Dion Jordan returned the ball to the Lions 3-yard line. On the next play, Ryan Tannehill connected with Mike Wallace for the touchdown, putting Miami ahead, 13-10. Prater made good on a 50-yard field goal early in the fourth quarter to knot the score at 13-13, but Sturgis' 20-yarder put Miami back on top by 3. As in the previous two games, the Lions had to rally on their final drive to win the game. Starting at their own 26 with 3:13 left in the game, the drive culminated with Stafford's 11-yard touchdown pass to Theo Riddick, putting the Lions ahead for good, 20-16. This was the third straight game in which the Lions trailed at the two-minute warning, then went ahead on their final drive. It was the second time in a month that Miami had lost a game in the final seconds, following a Week 7 loss to Green Bay in which the final touchdown was scored with 3 seconds remaining. According to STATS Inc., this is the first time Detroit has started a season 7-2 since 1993.

In the second half Jason Campbell threw a four-yard touchdown pass to Antwaan Randle El and the Redskins took the lead at 10-6.  In the fourth quarter Steve Smith scored on an 8-yard pass from Jake Delhomme to give Carolina a 13-10 lead.  Later in the fourth quarter Jason Campbell threw to Chris Cooley for a 66-yard touchdown giving the Redskins the lead for good.  Carolina threatened near the end of the game, but a Jake Delhomme pass was intercepted in the endzone by Redskins Safety Sean Taylor.  With the 17-13 victory, the Redskins record stood at 4-7.
