Lesson Activity Completion shows "partners"

I had to assign several Lessons in Unit 5 for homework. For some students, the green dots have an icon that says “worked with a partner”. Is there a way for me to see which parts of the lesson each partner completed? I’m concerned that one student did the lesson and then the other 2 may have copied and pasted his code.
