How I would recommend setting up the paper:
Paragraph #1: first selected chapter = accurate description (i.e., “The first chapter I found interesting is….”)
Paragraph #2: first selected chapter = detailed application (i.e., “How I could use ‘Chapter X’ in my this career is…)
Paragraph #3: second selected chapter = accurate description
Paragraph #4: second selected chapter = detailed application
Paragraph #5: third selected chapter = accurate description

Paragraph #6: third selected chapter = detailed application

The three chapter is (1)Physical activity and society (2) current trends and Kinesiology career (3) evidence base practice in Kinesiology

1800 words at least, double space.
