Final answer:
The item stored closest to the ground would be Fish.
Step-by-step explanation:
If all of the following items were stored on the same rack on the same wall, the item stored closest to the ground would be Fish. This is because gravity pulls objects downwards, and in this case, the weight of the fish is not counteracted by any other forces that would cause it to be higher up on the rack. The other items like Beef, Pork, Chicken, Lamb, and Fish would be stored above the fish.
