Quizplus · Accepted Answer

The two types of sources for review are generally considered to be primary sources and secondary sources. Primary sources are original documents or data sources created at the time of the event or study, while secondary sources are interpretations or analyses of the primary sources created after the fact. Examples of primary sources include data sets, surveys, and original research articles, while secondary sources may include textbooks, review articles, and meta-analyses. While options A and B are also common types of sources, they are not the primary distinction between different types of sources for review. Option D is not a commonly used distinction in research methodology.
