What is a another title that helps let the audience know what the section is about

Hello. You did not enter the text to which the question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.

There are only two titles in a text, when one of them is placed as a subtitle, which presents itself as a secondary title that complements the first title and that expands the perception on the subject that the text will address.
