Answer:
Extraneous details.
Explanation:
Extraneous details are referred to as something that is coming from outside(external) and does not contain relevance to the content or context. These details are not pertinent and not properly belonging to the text. Thus, these details are elaborated as pieces of information that are not significant to the meaning or purpose of the author. These details are deliberately introduced by the author to the text in order to fill up the gaps and not to signify something.
