Answer:
C. Education
B. Biased
Step-by-step explanation:
In order to stablish 100% credibility of a source, you should keep in mind to:
Consider the author’s scholarly education: Within each field, there are a handful of scholarly thinkers considered the giants of the discipline. For example in literary theory, Jacques Lacan, Jacques Derrida, and Michel Foucalt are three towering figures whose work provides the bedrock of the discipline.
Avoid self-published material at all costs: If an author is unable to convince a publisher to house their ideas, it’s likely because their ideas carry little weight. Never cite an author who self-published their work.
