The authors employ these details to 'strengthen their ideas and opinions' and convey them with more efficacy and clarity. These details may include the facts, comparison, statistics or quotation that would serve to enhance the validity of the author/speaker's claim or idea and make it more illustrative and clear for the audience to accept, believe, and elicit the desired response.
