The correct answer is C. A good reader attempts to distinguish between essential and nonessential details
Step-by-step explanation:
In texts, the supporting details refer to statement or pieces of evidence such as examples, quotations, statistics or reasons that help the author to explain and prove the main point or claim of a text. Additionally, during text analysis supporting details are kay as they allow the reader to know the reasons and information the author provides and whether these are logical and strong enough to prove the claim. Additionally, while analyzing a text ideally the reader should determine which details are essential and which ones are not as only essential details support effectively the claim of an author. Therefore, the statement that is true about supporting details is that "a good reader attempts to distinguish between essential and nonessential details".
