Correct answer to question 17 (Tank Vehicles): A quick lane change can start a side-to-side surge that is hard to control

Why

A sharp lane change sets the liquid rocking side to side, and that surge can keep building after the maneuver is done, which is why the movement itself needs to be gradual.
