This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What controlled comparison will help you use visible test evidence to infer that unseen agents can move between surfaces?
Getting the simulation ready…
1Change one thing
2Say what will happen, then run it
3Finish: say what you found
What counts as evidence
Select the measured comparison that directly addresses the prediction.
Name the changed condition, cite one result, and connect it to this goal: Use visible test evidence to infer that unseen agents can move between surfaces.
Your controlled comparison, measured result, revised model, and transfer claim become inspectable scientific evidence.
