Which of the following describes an advantage that secondary sources have over primary sources for historians?

Primary sources provide a first-hand account of an event or time period and are considered to be authoritative. They represent original thinking, reports on discoveries or events, or they can share new information.

On the other hand, secondary sources often use generalizations, analysis, interpretation, and synthesis of primary sources.

Therefore, primary sources provide the most accurate information. If you need simple, unaltered information about an event, use a primary source.
