10. Diffusion means:
a. cultural traits are expressions of our biology.
b. the environment is responsible for culture change.
c. cultures borrow ideas, material items, and concepts from each other.
d. people are often unwilling to move to new locations.
The correct answer is c. cultures borrow ideas, material items, and concepts from each other.
Diffusion refers to the process in which cultural traits, such as ideas, material items, and concepts, spread from one culture to another. It occurs when cultures come into contact with each other and exchange or adopt elements of each other's culture. This can happen through various means, like trade, migration, conquest, or technological advancements.
To arrive at this answer, you can analyze the given options and determine which one accurately describes diffusion. In this case, options a and b do not reflect the concept of diffusion since they focus on different aspects of culture change, such as biology and the environment, respectively. Option d is unrelated to diffusion as it refers to the willingness of people to relocate.
By process of elimination, option c remains as the only choice that actually defines diffusion – the borrowing or exchange of cultural traits among different cultures.
