Expertise or official status in a field is called what?

• A. Authority
• B. Credibility
• C. Trust
• D. Evidence

Answer: (A)

Authority is the term for expertise or official status in a field. It means the person is recognized as knowledgeable in that area because of credentials, position, or a proven track record, so audiences tend to accept what they say about that topic. This differs from credibility and trust, which relate to how believable a source seems or how confident you feel about them in general, and from evidence, which are the actual data or facts used to back a claim. For example, a doctor’s statements about health topics carry authority because of medical training and licensing, whereas a celebrity’s opinion on medicine might be influential but doesn’t automatically carry authoritative status unless they have relevant qualifications.
