Organizational structures refer to the way the content in a text is displayed and organized which allows the author to develop ideas properly depending on the topic and focus of the text. Most common organizational structures include sequence, chronological, spatial, problem and solution, the order of importance and compare and contrast. In the case of compare and contrast organization, this type of text organization analyzes the differences and similarities between two or more topics for example places,animals, technological devices, programs or sports by analyzing first the aspects of one element and then the other element or by comparing and contrasting certain aspects of both elements at the same time. Because of this, this type of organization is suitable if the topic contains two or more elements as this allows the author to analyze the elements individually and relate it features to the other element or elements. Considering this, for a writing assignment describing swimming and gymnastics compare and contrast is the most logical organizational structure as this allows the author to create a text in which both elements are equally important and relate to the other through differences or similarities.
I’ve never read the book but if you have this may help. Figurative language and the use of imagery makes the book come alive.

Imagery is using the 5 senses (taste ,touch ,hear ,smell , & sight) to give the audience a vivid picture of the story they are reading.
