A writer wants to arrange reasons by logic, audience concerns, and importance. Audience: a computer science curriculum committee. Thesis: computer science majors should take a course in technology ethics. Possible reasons: I. case discussions can help students recognize consequences beyond code correctness; II. ethical reasoning prepares graduates to make responsible choices in professional settings; III. the course can be paired with existing project work rather than added as an unrelated requirement; IV. students will design systems that affect privacy, access, and public trust. Which order should the writer choose?
