Why do baffles have openings rather than being solid dividers across the entire tank?

Pick an answer

1. Openings let liquid pass through slowly and let the tank be loaded, unloaded, and cleaned as a single unit
2. Openings exist purely by manufacturing accident with no intended purpose
3. Openings are required only for tanks carrying food-grade liquids
4. Solid dividers would improve surge control more than baffles with openings, which is why some older tanks used them instead
