* Primary information is original, firsthand data collected directly from the source. This could be through experiments, interviews, surveys, or direct observation.
* Secondary information is information that has been compiled or analyzed from primary sources. It's a reinterpretation or summary of existing data.
A brochure is created to present information about a product, service, or event. It draws upon and summarizes information that was originally collected elsewhere (likely through primary research). Therefore, the information within it is considered secondary.
