A social worker reads an article in Time magazine about student intolerance of conservative political speakers. Which type of source is this?

The correct answer is secondary source. A secondary source provides interpretation, analysis, or commentary on primary data or original content. The article in Time magazine discusses a specific event or phenomenon—student intolerance of conservative political speakers—but it does so by summarizing, analyzing, or synthesizing information from primary sources such as interviews, original research, or direct accounts.

In research, primary sources are original materials that provide direct evidence or firsthand accounts, such as interviews, surveys, or original studies. Tertiary sources compile and summarize primary and secondary sources, such as encyclopedias or textbooks. Peer-reviewed sources are academic articles that have undergone a rigorous review process by experts in the field, ensuring high quality and credibility. A magazine article like the one mentioned would typically not be peer-reviewed but would serve as a secondary source by interpreting and discussing the events surrounding the topic.
