question: The 365-day and the 260-day calendars identified and named the days, but not the years. The combination of a solar year date and a 260-year date was enough to identify a specific date to most people's satisfaction, as such a combination did not occur again for another 52 years, above general life expectancy. To measure dates over periods longer than 52 years, the Mesoamericans devised the Long Count calendar. This calendar system was probably developed by the Olmecs and later adopted by the Maya. The use of the long count is best attested among the classic Maya, it is not known to have been used by the central Mexican cultures. The Long Count calendar identifies a date by counting the number of days from August 11, 3114 BCE in the proleptic Gregorian calendar or September 6 3114 BCE in the Julian Calendar . Rather than using a base-10 scheme, like Western numbering, the Long Count days were tallied in a modified base-20 scheme. Thus 0.0.0.1.5 is equal to 25, and 0.0.0.2.0 is equal to 40.
Answer this question: Who did the Mayans probably adopt the calendar system from?
answer: the Olmecs

question: In week 4, the Lions traveled south to Arlington, Texas to take on the Dallas Cowboys. The Cowboys dominated the first half, putting the Lions in a big hole for the second straight week. First came a 25-yard touchdown catch by Dez Bryant. In the second quarter, Bryant scored again on a 6-yard touchdown catch. Dallas added more points with a 41-yard field goal by Dan Bailey. The Lions then got their only points of the first half with a 33-yard field goal by Jason Hanson. The Cowboys responded with a 35-yard field goal just before halftime. After the break, Dallas added more points with a 1-yard touchdown pass to Jason Witten, putting them up 27-3. The Lions responded with two consecutive defensive touchdowns: first a 34-yard interception return by Bobby Carpenter, then a 56-yard pick-6 by Chris Houston. The Cowboys scored their final points of the game with a 23-yard field goal late in the third quarter. In the fourth quarter, the Lions continued their comeback with a 23-yard touchdown catch by Calvin Johnson. They made it a three-point game with a 51-yard field goal by Jason Hanson, then Romo threw an interception to Stephen Tulloch, and took their first lead of the game late in the final quarter when Calvin Johnson caught his second touchdown of the game from 2 yards out to become only the second player in NFL history to record at least two touchdown catches in 4 straight games (the other to do so is former Vikings receiver Cris Carter). The Lions defense held off Dallas for the win. Like the previous week, the Lions came back and won it in the final moments of the game after being down by a large margin at halftime. This was also the largest comeback the Dallas Cowboys have ever allowed, and it is the largest comeback by a road team in NFL history as the Cowboys were up by 24 in the 3rd quarter. It was the first time the Lions started 4-0 since 1980. This also was its franchise-record fifth straight road win. Ironically, their last game at Dallas saw the Lions lose their franchise-record 26th straight road game.
Answer this question: How many Touchdowns did Calvin Johnson catch?
answer: 2

question: The coastal areas of the Andaman Sea are characterized by mangrove forests and seagrass meadows. Mangroves cover between more than 600 km2  of the Thai shores of Malay Peninsula whereas seagrass meadows occupy an area of 79 km2 .:25-26 Mangroves are largely responsible for the high productivity of the coastal waters - their roots trap soil and sediment and provide shelter from predators and nursery for fish and small aquatic organisms. Their body protects the shore from the wind and waves, and their detritus are a part of the aquatic food chain. A significant part of the Thai mangrove forests in the Andaman Sea was removed during the extensive brackish water shrimp. Mangroves were also significantly damaged by the 2004 tsunami. They were partly replanted after that, but their area is still gradually decreasing due to human activities.:6-7 Other important sources of nutrients in the Andaman Sea are seagrass and the mud bottoms of lagoons and coastal areas. They also create a habitat or temporal shelter for many burrowing and benthic organisms. Many aquatic species migrate from and to seagrass either daily or at certain stages of their life cycle. The human activities which damage seagrass beds include waste water discharge from coastal industry, shrimp farms and other forms of coastal development, as well as trawling and the use of push nets and dragnets. The 2004 tsunami affected 3.5% of seagrass areas along the Andaman Sea via siltation and sand sedimentation and 1.5% suffered total habitat loss.:7
Answer this question: How many more acres, in km2, of mangrove forests than seagrass meadows occupy the Thai shores of the Malay Peninsula?
answer:
521
