What types of materials were commonly found among the California Indians?

The correct answer encompasses a broad range of materials commonly utilized by California Indians, reflecting their diverse lifestyles and the natural resources available to them. Subsistence agricultural implements were vital as many California tribes practiced forms of agriculture, growing native crops and managing landscapes to support their communities. Money, often in the form of trade goods or resources, was also an important aspect of their economies, facilitating exchanges between tribes. Furthermore, musical instruments played a key role in cultural practices, including ceremonies and celebrations, indicating the significance of music in their social and spiritual life.

While agricultural tools and musical instruments are present in other options, they do not represent the full spectrum of materials used by California Indians. The inclusion of money illustrates an economic system, and subsistence agricultural implements underscores their reliance on farming. The other choices focus more narrowly on specific categories and do not capture the comprehensive array of materials that were integral to the way of life for California Indians.
