The correct answer is D) cosmic events.
An important part of Mayan culture was religion, which related stories about the gods and revolved around cosmic events.
The Mayas were great astronomers. They had great temples and observatories in their main cities such as Palenque, Uxmal or Chichen Itza, in the nowadays Mexican states of Chiapas and Yucatan.
They are the creators of the diverse Mayan calendars such as the Haab, a 365-day solar calendar that is divided into 18 months of 20 days each. The other calendar is the Tzolkin or divine calendar. A 280-day calendar with 20 periods of 13 days. The last calendar is called the Long Count, that is used to track longer astronomic events.
