Answer and Explanation:
Brian learns things that are very valuable for his survival and lives in general. First, he learns to remain calm even in adverse situations. That's because, Brian can understand that if he panics, he won't be able to reason properly and this will limit his chances of survival. He also learns that he must protect his food while watching the animals, and he learns that his shelter must be very safe and strong, so it must be well built and established.
