Answer:
The correct answer is A. One advantage a primary source has over a secondary source is that a primary source is typically free of outside interpretation.
Step-by-step explanation:
A primary source is a source and therefore information that comes directly from people who are involved in a particular event, person or time span. The information itself therefore comes from the period under discussion and was not compiled or learned from second hand later. However, primary is by no means a synonym for superior and primary sources may not always be seen as more valuable over secondary sources because the personal involvement often results in strong "coloring" of the information given, through the use of euphemisms, omission of unwelcome facts exaggeration of facts of which one is proud or an excess of admiration or dislike of others involved.
