Build the SIR chain
The middle is fixed. Place the two missing compartments until the model flow becomes visible.
I Infectious People who can pass the disease on.
Exactly right.
In the SIR chain, people move from S to I and then to R. The key model assumption is permanent immunity: once someone is in R, they stay there.

What is the effect of mitigation?
One answer fits the model.
Ready.
Exactly.
Mitigation reduces risky encounters. This pushes the effective reproduction rate down, resulting in a flatter wave.

Which statement belongs to which component?
Ready.
Perfect.
You have mastered the levers. While and duration define the biological frame, mitigation is our active tool to control the wave.

In MiniLab 1, you have:
- grasped the fundamental logic of the SIR model
- discovered how individual cases escalate into an outbreak wave
- seen firsthand how a "contact brake" can flatten the curve
- learned why real outbreaks are more complex than a simplified model
- realized why these simulations are vital for public health authorities
