Why do baffles reduce, but not fully eliminate, the effects of liquid surge?

Pick an answer

1. Baffles completely stop all liquid movement inside the tank, turning it into several fully sealed sections
2. Baffles have no actual effect on liquid movement at all
3. Liquid can still move through the openings in the baffles, just more slowly than in an unbaffled tank
4. Surge is entirely unrelated to whether baffles are present
