The purpose of speech is to pass knowledge down through generations and to commuinicate to others
The correct answer to this open question is the following.
The three practical examples from your own cultural background that demonstrate the assertion that culture is dynamic and socially created, are the following.
1.- Family traditions. We value family traditions. The Mother is the most important figure of the family and through the pass of time, although women have been playing a more prominent role in society, women are still considered the pillar of the family institution.
2.- Honoring the ancestors. People show so much respect for the elderly and our ancestors. We believe that they pass knowledge from one generation to the other. And this is something that young people still honors, no matter they think differently. Young people and children are taught to follow this belief system that has adjusted through times, but the core of the teaching still exists.
3.- Rites. Songs and dances. Our folklore is still so alive. Today, our music and dances are not so ceremonial as they used to. We have incorporated modern music, rhythms, and styles to sing about our roots. In the past, we used traditional instruments and chants but today we use electric guitars, keyboards, and modern sounds to keep telling our stories that are shared with other people that do not belong to our culture.
