Which of the following is an example of cultural diffusion?

Cultural diffusion refers to the process through which cultural beliefs, practices, or items are spread from one group or society to another. The correct answer, which highlights the introduction of tacos into North American cuisine, exemplifies this idea perfectly. Tacos, originating from Mexican culture, have been embraced and adapted within various North American contexts, showcasing how one culture can influence another through the sharing and incorporation of food traditions. This blend of culinary influences illustrates the dynamic nature of culture and how it evolves through interaction with different societies.

The other options do not illustrate cultural diffusion in the same way. Adopting a new language while losing a mother tongue focuses more on language shift rather than the spread of cultural practices. Engaging with local customs enhances cultural exchange, but choosing not to engage suggests a lack of cultural interaction that does not align with the concept of diffusion. Lastly, maintaining traditional farming practices without change indicates cultural stasis rather than diffusion, as there is no exchange or influence from other cultures occurring in that scenario.
