Explanation:

Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research.

Primary sources help students develop knowledge, skills, and analytical abilities. When dealing directly with primary sources, students engage in asking questions, thinking critically, making intelligent inferences, and developing reasoned explanations and interpretations of events and issues in the past and present.

Secondary sources provide good overviews of a subject, so are particularly useful if you need to find about an area that's new to you. They are also helpful because you can find keywords to describe a subject area, as well as key authors and key references that you can use to do further reading and research.

Have a great day! :)
