The correct answer is: Both A and B.
The Cave of Lascaux was closed to the public in 1963 due to both the erosion of the cave floor and the development of colonies of algae and a calcite veil on the cave walls.
To arrive at this answer, we need to understand the reasons behind the closure of the cave.
First, the erosion of the cave floor was a problem. Constant foot traffic by visitors caused the delicate cave floor to become eroded. This posed a risk to the preservation of the cave and its precious artworks.
Second, colonies of algae and a calcite veil were developing on the cave walls. These naturally occurring formations happen due to the presence of moisture and mineral-rich water. They were beginning to cover the prehistoric paintings, jeopardizing their visibility and long-term preservation.
Lastly, unintentional smudging of the artwork by visitors also played a role in the decision to close the cave. The oils and moisture from human touch can cause irreversible damage to the ancient paintings.
Considering these factors, the French authorities decided to close the Cave of Lascaux to protect its delicate environment and preserve the invaluable prehistoric art for future generations.
