What text structures does the author use?

How effective is the text structure in sharing important ideas?

Explanation:

The organizing of information in a text is what is referred to as a text structure. The organization, therefore, determines the significant ideas in the book and identities them quickly to the reader. The text thus can be organized in chronological sequence through contrast and comparison.

When the reader develops the interest of evaluating the text, merely the reader is trying to weigh the quality of the structure and its effectiveness to the audience. Therefore the text structure should always be active and communicate significant ideas.
