Which of the following does not need to be considered when you are determining a sources credibility

There are no answer choices, but you don't need to know the author/publishers birthdate or favorite where they live. Just when they did it, who published it, the year they published, etc.

Since there are no choices ... What you DO need to have to know credibility is who the author is, the author's credentials, where the piece was published, the date of the piece (things change over time), how official the piece sounds ...
