Final answer:
Children dying is not proof of magic working for the Yanomamo people.
Step-by-step explanation:
The statement that children dying is proof to the Yanomamo that their magic works is false. It is important to note that correlation does not prove causation. The belief held by the Yanomamo does not necessarily mean that their magic is responsible for the deaths of children. Other factors could be at play, such as disease or natural causes. It is vital to approach such cultural beliefs with sensitivity and respect, and to consider multiple perspectives and explanations.
