🧠 WHY THESE QUESTIONS ARE TRICKY

They test whether you:

✔ Trust data, not appearance
✔ Use conservative decisions
✔ Understand integrity ≠ visual condition
✔ Follow code logic under pressure

🚀 FINAL EXAM RULE

If confused, choose answers that:

✔ Verify
✔ Reassess
✔ Investigate
✔ Use conservative logic

NOT:
❌ Assume
❌ Ignore
❌ Accept blindly
