1. What does superposition mean?

A particle has a fixed position
A particle can exist in multiple states at once
A particle disappears

2. What is quantum entanglement?

Particles merging together
Particles moving very fast
Two particles affecting each other instantly over distance

3. What happens when a quantum system is measured?

Nothing changes
It randomly explodes
It settles into one definite state

4. Why did Einstein call entanglement "spooky"?

Because it involves ghosts
Because it allows instant connections across distance
Because it is invisible

5. What does quantum physics suggest about reality?

It is always fixed and predictable
It is probabilistic and not fully defined until observed
It does not exist
