3. In Unity C#, what is a Coroutine used for? → Pausing execution and resuming it over multiple frames without blocking the main thread
4. Which Unity physics method should be used to move a Rigidbody in a physics-safe way each fixed frame? → MovePosition() in FixedUpdate()
5. Why is client-side prediction used in multiplayer games? → Hide latency by simulating locally before server confirms
6. Which component must be attached to a GameObject to enable Unity's physics simulation on it? → Rigidbody
7. What does the [SerializeField] attribute do in Unity? → Makes a field visible in the Inspector even if it is private
8. When you click this button, what method gets called? → AudioSource.Play
9. How should you manage test anxiety? → Use preparation, deep breathing, positive self-talk, and arrive early to feel in control

12. The animation window's graph view displays animations: → Curve Editor
13. What is paper trading? → Practicing trading with simulated money to test strategies without financial risk
14. In Unity, what does the 'Constraints' section in the Rigidbody component allow you to do? → Freeze specific axes of position or rotation to restrict physics movement
15. What does a Particle System's 'Emission Rate over Time' property control? → How many particles are spawned per second
16. What is the purpose of the 'static' keyword on a Unity C# field? → It makes the field shared across all instances of the class rather than per-instance

29. In Unity's Animator, what is an 'Avatar' used for? → Mapping a humanoid skeleton to Unity's standard bone structure for retargeting animations
30. In Unity scripting, what is the purpose of the 'DontDestroyOnLoad()' method? → Preserves a GameObject across scene loads so it isn't destroyed when a new scene is loaded
