Textual evidence is the facts that are present in a text and that constitute the support for the theses or claims in the text.
On the other hand, the Inflection can have two different connotations, both important when reading. First, inflection can be the uprise or lowering of the tone of the voice when reading. Second, it can refer to the change of form that words undergo to mark case, gender, number, tense, person, mood, or voice.. Inflections also include changes in ending and changes within the root of the word, for example: he - him - his
So, to answer the question in the most logical way, I would say that:
Textual evidence and inflection are important both when reading by yourself and listening.
