question: 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.

Game SummaryThe San Diego Chargers got out to a fast start from Darren Sproles' 89-yard opening kickoff return for a touchdown. After a later field goal, Sproles would follow up with a 45-yard punt return for a touchdown in the first quarter. He became only the second player in NFL history, and first since 1958, to return a kickoff and a punt for touchdowns in the opening quarter. San Diego failed on the subsequent two-point conversion to lead 16-0. With 8:47 left in the second quarter, LaDainian Tomlinson rushed for a four-yard touchdown to give the Chargers a 23-0 advantage. Peyton Manning would lead the Colts down the field and capped the drive with an 8-yard TD pass to receiver Reggie Wayne. Later, in the fourth quarter, Manning threw a 7-yard score to running back Kenton Keith. Twenty-five seconds later, linebacker Gary Brackett recovered a fumble in the endzone for a touchdown. The Colts attempted a rush for the two-point conversion to tie the game 23-23, but were held short. With a 23-21 lead, the Colts got the ball back with only a few minutes left in the game. They marched down the field into San Diego territory. On fourth down with 1:31 remaining, Adam Vinatieri was put in for a 29-yard field goal try. Vinatieri, despite being known for his clutch kicks and having over a 95% success rate in field goals under 30yards, missed wide to the right. Vinatieri missed an earlier 42yard try at the end of the half, going 0-2 in the game. It was the first time since 2001 Vinatieri was 0-2 kicking field goals. The Colts would get the ball back, but Manning would seal a Chargers win by throwing an interception with no time remaining. Manning struggled in the game, throwing a career-high 6 interceptions. The mark is also a Colts franchise record. Chargers cornerback Antonio Cromartie had three interceptions in the game, becoming one of only 11 Chargers to have three picks in a single game. The Colts were heavily injured on both sides of the ball. Receivers Marvin Harrison and Anthony Gonzalez, left tackle Tony Ugoh, and tight end Dallas Clark missed the game. In perhaps the biggest blow to the Colts, Dwight Freeney injured his left foot and was carted off the field. Three days later, it was confirmed that Freeney had suffered a season-ending Lisfranc fracture. By the end of the game, a total of nine Colts on their 53-man roster either did not play due to injury or were injured in the game. The Colts dropped to 7-2, remaining in first place in the AFC South division. Meanwhile, the Chargers moved to 5-4 and clear first in the AFC West.

By the end of the game, how many Colts were left from the roster that could play?
A: 44

Problem: In December 1774, a Siamese supported rebellion broke out at Lampang in Lan Na, and soon spread. On 15 January 1775, the rebels took Chiang Mai, and overthrew the Burmese installed government. In November 1775, two Burmese armies of 35,000 were to invade Lan Na and Siam. But because of a mutiny by a senior commander, the southern army lost a significant portion of the troops. The remaining Burmese armies fought their way in. The northern army managed to capture Chiang Mai, albeit at a great cost, and the southern army took Sukhothai and Phitsanulok in central Siam. However, the invasion forces were too small to overcome the Siamese defences, and were bogged down. The armies withdrew in June 1776 after Hsinbyushin died. Hsinbyushin's successor Singu stopped the war with Siam, and demobilised much of the army. The decision was well received by the war-torn country. The people had grown tired of constant conscriptions to fight in "ever-lasting wars" in remote regions they had never heard of. But the king had unwittingly given up Chiang Mai, which proved to be the end of two centuries of Burmese rule there. Likewise, Singu took no action in 1778 when Vientiane and Luang Prabang stopped paying tribute, and came under Siam's sphere of influence.

How many years passed since a Siamese supported rebellion broke out and the rebels took Chiang Mai?
