The correct answer is:
2. Stone with red writing
Step-by-step explanation:
With this image, it is possible to think that a written language would normally represent the association of some symbols with a spoken language. Nowadays, the writing instruments or symbols used to interpret language are considered a representation and it is also important to take into account that the written language is not considered a natural manifestation in human beings as the spoken language is. Therefore, the image of the stone with red writing could be an evidence that the Neanderthals had already the capacity of communicating with a spoken language.
