Final answer:
The author includes details at Megan's home in paragraphs 5 and 7 to support the main point or theme of the text.
Step-by-step explanation:
The most likely reason the author includes details at Megan's home in paragraphs 5 and 7 is to provide a specific and tangible example that supports the main point or theme of the text. Including details about Megan's home helps to create a sense of realism and allows the reader to better understand the character or situation being described. For example, the author may describe Megan's messy room to emphasize her disorganized and chaotic lifestyle, or describe her comforting and welcoming home to highlight her nurturing and caring nature.
