Which of the following is an example of secondary research?

Secondary research involves the analysis and interpretation of data that has already been collected by others. A critical analysis of a poem fits this definition as it involves examining, interpreting, and drawing conclusions based on a poem that exists as a primary source. This kind of analysis relies on previously published works and the ideas and interpretations of the analysis author, thereby classifying it as secondary research.

Other options involve primary research methods. Conducting a survey of user opinions collects new data directly from participants, while a direct interview with an author also gathers firsthand information. A transcript of a speech represents primary data since it records speaker's direct communication. All these options focus on gathering and presenting original information rather than analyzing existing sources.
