The provided passages do not detail the specific evidence the author of "Lives" by Plutarch provides within the text. The description states that the book contains "Character studies comparing statesmen and generals of pre-Christian Greece and Rome" [Passage 1]. This indicates the *type* of content, but not the evidentiary basis for those character studies.
Therefore, it is not possible to answer what evidence the author provides based on the given passages. The passages describe the subject matter of the book but do not offer any information about the author's methods or the evidence used to support their character studies.
