Answer:
B. Bantu tribe members did not use relative size as a cue to depth
Explanation:
They found this out after telling members of the Bantu cultures to interpret a picture and compared it to the interpretation of picture made by European people.
The picture shows a hunter and an elephant that is far away from the hunter (which is why the elephant is drawn smaller). But as it turned out, the majority of Bantu people do not know that the size meant that the elephant is located far away. They just thought it's a small elephant.
