Step-by-step explanation:
Paleolithic Sculptures
The question pertains to the number of sculptures from the Paleolithic period that have been discovered. During the Paleolithic, or Old Stone Age, which ranges from around 30,000 BCE to 10,000 BCE, early humans created some of the first examples of representational art, which include sculptural works mainly in the form of figurines, beads, and decorative utilitarian objects. Notably, these works were constructed with a variety of materials such as stone, bone, ivory, clay, and wood.
In terms of known discoveries, there are over two hundred caves across Europe and Asia, particularly in regions such as southern France and northern Spain, where these sculptures and other artworks have been found. This includes the well-known Venus or Woman figurines, which exhibit common stylistic features and are believed to represent ideas of fertility or motherhood. The most famous example is the Woman of Willendorf.
Considering the evidence, the answer to the question of how many sculptures from the Paleolithic period have been found is (d) Exact number unknown, as it is challenging to pinpoint an exact figure due to various factors such as the movement of artifacts from original contexts and incomplete archaeological records.
