Answer:
3.)primary
4.)secondary
Explanation:
Historical sources constitute the raw material of History. They include all the documents, testimonies or objects that transmit us significant information regarding the events that have taken place, especially in the past. Within them, and considering the value that others also have, the written sources are the basic support to build history. The sources are classified as:
• Primary sources. They are those that have been developed practically at the same time as the events we want to know. They come to us without being transformed by any person; that is, as they were done at the time, without being subject to any subsequent modification.
• Secondary sources. They are also called historiographic. They are those that are made from primary sources: books, articles, etc.
