Question

You live 200,000 years ago, in a time known as the Stone Age. A local toolmaker has offered to teach you his skill. You will watch carefully as he strikes two black rocks together. A small piece flakes off. You try to copy him but the rocks just break. Finally, you learn to strike the rock just right. You have made a sharp stone knife!

Question: How will you use your new skill?

Answer 1

You learned how to use two resources to make one important resource

Answer 2

To survive?
Or you just took two elements to make one tool so you can definitely do that with other materials
