<em>The best place to find reference sources for a scholarly essay is</em><em> A. the library. </em>
Explanation:
<u>Reference sources </u>provide general background information -facts, dates, definitions and more -to students and writers in general. These tools (that can be dictionaries, atlases, encyclopedias, etc.) are usually the first step to carry out a research, especially if the field is unfamiliar for the writer. Since the scholarly essay will be based on these sources, it is important that they are non-biased and reliable. The best place to find a reference source that meets with these requirements is the library.
