Answer:
I would say that the answer is the third option: "how one's culture is often determined by where they live on Earth".
Explanation:
Culture encompasses many aspects of one's life including their language, traditions, beliefs, and even what they eat and wear. Since living in a rocky terrain will result in the masses of people having a diet consisting of grapes and olives, they'll naturally pass down whatever recipes they've accumulated, from generation to generation.
Hope this makes sense. This is a more simplified version of my answer, so if you need more clarification please let me know.
