When we're writing a paragraph (about the theme of a text, for example), we can use the PIE structure. Each of these letters stands for one part of the paragraph:
P - point - the main idea (the theme);
I - information/illustration - information that supports (illustrates) the point (like quotes in the given example);
E - explanation - explanation about how the illustration supports the point.
Based on the given information, we can see that the given paragraph doesn't contain the explanation. We have the theme and examples that illustrate it, but there is no explanation that connects them.
