(C) There was no strong religious tradition in Andean culture, compared with the Maya. (D) The Andeans had a system of writing, but the Maya did not.Explanation: There was little to no north-south traffic in the Americas, and certainly not among indigenous peoples between Mesoamerica and South America.
