The correct answer to this open question is the following.
Although there are no options attached we can comment on the following.
Some limitations that historians studying Mesoamerican cultures face when trying to get information is that these Mesoamerican civilizations such as the Aztecs, the Toltecs, the Olmecs, the Mayas, or the Zapotecs registered their stories and events in the form of "codices," which are a series of drawings or pictographs that are not easy to understand or to translate.
In the case of the Mayas, just a little bit is known about them because anthropologists and archeologists haven't been able to understand and translate their codices and teh Mayan stelae.
These Mesoamerican civilizations did not have an alphabet as we know it today. They sculped and craved in stones a series of codices, figures, and representations that must be translated and interpreted.
