Identify two ways in which early man used tools

Because of the lack of answer choices, I have to improvise. Caveman find rock. Caveman find walnut. Caveman smack walnut with rock to open. Caveman, after his successful meal, carves a stick to make it sharp. Caveman use sharp stick to stab things. Caveman pokes bear with stick. Caveman doesn't have the best odds. Caveman goes hungry tonight, but the bear does not.
