Which of these is a primary source about the discovery of the new world? a book written and researched by a noted historian an article written by an archaeologist who excavated in the caribbean a journal written by christopher columbus on one of his voyages a document sent to new world miners by a spanish official

The answer would be: C. A journal written by Christopher Columbus on one of his voyages!

This is because a primary source, is an artifact, book, article, etc. that was created at the time of a study or case. In this problem it was a journal that was written by Christopher Columbus, in his time! All of the other information was written after, and was information that had been researched!

I hope this helps some of you guys! Thanks

besides, if a global health system is established the quality levels will fall down because of the standardized of the health. the access to care will increase but the quality will be low because it depends on the money invested.
