Question

question 8 of 10
a historical source is most likely to be credible if:

a. nobody else has ever written about its conclusions.

b. the author has consistently written truthful material.

c. its conclusions are backed up by official government sources.

d. it was written by an author with a high level of education.

Explanation:

• Option A: If nobody else has written about its conclusions, it may lack verification or consensus, so it's not a sign of credibility.
• Option B: An author's consistent truthful writing is a strong indicator of credibility as it shows reliability over time.
• Option C: While government sources can be credible, a historical source's credibility isn't solely dependent on being backed by them (and some government sources may not be accurate).
• Option D: A high level of education doesn't guarantee the author's work is credible; they could still produce inaccurate or biased content.

Answer:

B. the author has consistently written truthful material.
