The correct responses are:

1. The Paleolithic inhabitants sealed off the cave once all the walls and ceilings had been painted.
2. The Paleolithic inhabitants covered their artwork with a layer of animal fat to protect the paintings.

The correct response is: the Paleolithic inhabitants sealed off the cave once all the walls and ceilings had been painted.

Explanations:
- The Paleolithic inhabitants of Altamira sealed off the cave where the artwork was located in order to preserve it. They did this by blocking the entrance to the cave once they had finished painting all the walls and ceilings.
- By sealing off the cave, they created a protective environment that helped protect the artwork from natural elements, such as weathering, and also from human interference.
- This protective measure allowed the paintings to remain undisturbed for thousands of years, until their rediscovery in the late 19th century.

It's important to note that the other options presented, such as covering the artwork with animal fat or the natural/intentional collapses, are not the reasons that preserved the art of Altamira until modern day.
