Step 1: Apply the relevance-plus-realism checklist to both arguments regarding mandatory internships.
Step 2: Argument I - relevant, since it addresses a direct consequence of making internships mandatory; realistic, since uneven availability of internships across different fields is a genuine, practical obstacle that could delay graduation. It passes.
Step 3: Argument II - relevant, since it addresses the direct intended benefit of the mandatory policy; realistic, since improved employability from practical experience is a real and substantial gain colleges care about. It also passes.
Step 4: Both arguments raise genuine, policy-relevant considerations that clear the checklist.
Correct option: (3) Both arguments are strong.
