How can text features help a reader analyze an author's argument?

A. They show where the most important information about the argument is located.
b. They reveal the main points and show how factual support for the argument is organized
c. They include examples and reasons that support the argument not found in the main text.
d. They highlight opposing claims and evidence that might counter the argument

All of the options mentioned can help a reader analyze an author's argument, but option B is the most accurate. Text features, such as headings, subheadings, bullet points, and bolded or italicized text, can reveal the main points of an argument and show how the factual support for the argument is organized. This can help the reader understand the structure and organization of the argument, as well as identify the key points being made by the author.
