Explanation:
1. Sacred/ritual calendar: Tzolkin
Civil calendar: Haab
2. (see document c)
3. The Tzolkin was the sacred calendar, set aside for special rituals, and religious practices and events. It was used alongside the Haab, the civil calendar used for predicting solar events and tracking the movements of the sun, moon, and even planets. The two calendars coincided every 52 years, inscripted onto stone wheels that turned, revolving for everyday.
4. Haab, both the civil and solar calendar would be the most likely option. It was quite accurate and advanced for its time, and the Mayans likely used it for certain seasons. Its system has been studied for centuries, with a year of 365 days in total, it isn't too different from our gregorian calendar.
5. As mentioned in the previous question, the Mayan calendar was the most modern and accurate of its time. It was studied and used to analyze the movements of stars and planets, with it also identifying harvest seasons and part of what led to our own calendar.
I hope this helped, even if I wasn't able to help you with question 2.
