Final answer:
The connections that justify the student registration system are: student takes classes, instructors teach students, and department offers courses.
Step-by-step explanation:
The connections that justify the student registration system are:
- Student takes classes: This connection is justified because the student registration system allows students to select and enroll in courses they want to take.
- Instructors teach students: This connection is justified because the student registration system assigns instructors to the classes that students have registered for.
- Department offers courses: This connection is justified because the student registration system lists the available courses offered by different departments, allowing students to choose from those options.
