Which is a primary source? a. a journal entry from a young bride traveling west b. an article in a current encyclopedia c. data on weather and climate d. a book about the people of ancient china

Hi! A primary source is something written from someone who experiences an event first hand. Encyclopedias and books about ancient China are not primary sources, because it was not written by people who experienced the even first hand. B and D are not the answers. Data on weather and climate can be current or in the past, but it's not really much about history or anything like that, so we can eliminate C. The only answer that makes sense is A, because journals are primary sources written by people who experienced it first hand. The answer is A.
