One compartment of your multi-compartment tank vehicle is only partly filled while the others are full. What should you expect?

Pick an answer

1. A partly filled compartment behaves identically to a full one in every way, since each compartment is sealed off from its neighbors
2. No compartment can surge unless the entire tank is partly filled
3. Multi-compartment tanks eliminate surge entirely regardless of fill levels
4. That compartment can still surge on its own, even though the fully loaded compartments have little room for the liquid to move
