Iam takings a pre-test, and stuck on this question.

answer: b: supported by key details

explanation:

[why it's not a] - fantasy books exist, and are not supported by history

[why it's b] - why would you write a story about something and give no details about it? if its the central idea of the text, it there will be details about it, whether it's dragons or chemistry.

[why it's not c] - plenty of texts are biased, fact based pieces, such as scientific papers, which are not allowed to have bias.

[why it's not d] - sometimes but not always is the central idea in the title. it often has a piece of the ideas in there, but it near impossible to fit everything you want to say in your text into just the title.
