The correct answer to this question is: TRUE.
The section written in all caps is a <em>conclusion</em> of the previous explanation, therefore, <em>it expresses the main idea in the text</em>. A conclusion consists of a recapitulation of the introduction, which usually expresses the main idea in a text. The first sentence wrote, "When the sun and moon are near the horizon, we notice that they are distorted from a circular form into ovals, and are usually of a reddish color" tells the reader what is the main information or idea the writer is trying to convey. All that follows is an explanation of the reasons why that phenomenon happens. In the end, the section written in all caps resumes the introduction and adds a summary of the information given. Thus, this section can be considered an example of the main idea presented in the beginning.
