Which of the following would not be considered an artifact by historians studying early Mesoamerican and South American cultures?

A piece of ancient pottery
A letter written by a 15th century Spanish conquistador
A rope bridge
A modern scholarly article

Respuesta :

A modern scholarly article, the first three are primary sources (Text or items from the time period being investigated) and the last one is a secondary source which was written by someone investigating that time period, therefor it is not an artifact
