Final answer:
Bronislaw Malinowski found that Trobriand Islanders use magic in situations beyond their control, such as long and dangerous sailing voyages, which is true.
Step-by-step explanation:
Bronislaw Malinowski proposed that when people cannot control matters such as wind, weather, and fish supply, they turn to magic. This is a true statement. Malinowski's fieldwork among the Trobriand Islanders revealed that they relied on magic and rituals to reduce anxiety for events beyond their control, especially before undertaking hazardous activities like long sailing voyages for the kula ring exchanges. These exchanges were not only vital for enhancing social status and reinforcing trade relationships but were also fraught with dangers that could not be planned for or avoided. Malinowski's comprehensive studies on the Trobrianders in his ethnography 'Argonauts of the Western Pacific' showcase this relationship between magic, religion, and the human need to make sense of and control the environment.
