4 before 6 because of the hole in 4.

2 and 3 at the same time.

The line is blocked between 2-3, so 3,6,&7 don’t get anything.

even if there’s no floor, they will all fill eventually. it may cause another noah’s ark situation, but what matters is that all the containers will be filled.

3/6/7 can’t be filled, the hole between 2>3 is plugged.
