What undermines the credibility of this argument?

Question

The author supports the argument with a figure that is outdated.
The author demonstrates a clear bias against electronic books.
The author cites a magazine that does not appear to be credible.

Answer 1

The figure being outdated undermines the credibility of the argument, as it may no longer reflect accurate information or data. The bias against electronic books also undermines credibility, as it suggests a lack of objectivity and potential manipulation of information to support personal preferences. Additionally, citing a magazine that is not seen as credible decreases the argument's credibility, as the information presented may not be trustworthy or reliable.
