In the articles “Elephants can lend a helping trunk” by Virginia Morell, “Elephants know when they need a helping trunk in a cooperative task” by Joshua M. Plotnik, and “Elephants console each other” by Virginia Morell they talk about how elephants played a task where they had to pull a rope with a partner to get food. In the article they describe it as a platform tied to a rope on both sides and the elephants have to pull the rope together to get the platform with food to get closer. But if one elephant pulled it alone on one side then the rope would get shorter on the other so they NEEDED to pull together. They had different types of this task for example they had it where it was to short for one elephant to reach so the other didn't bother
