If a teacher discusses the history of a church, what means of communication is he using?

When a teacher discusses the history of a church, the means of communication they are using is primarily categorized as communication through material culture. This form of communication encompasses the physical objects, artifacts, and structures that convey meaning and significance about a particular culture or society. In the context of a church, the buildings themselves, as well as associated artifacts like religious texts, architectural styles, and art within the church, provide historical insight and convey the values, beliefs, and practices of that religious community.

Material culture effectively embodies the ideas and history of a society, allowing for a deeper understanding of the context surrounding the church's development and its role within the community. This communication is not just verbal or written; it includes the tangible items and structures that tell the story of the church's evolution and significance over time.

The other options mentioned, such as communication by visual symbol, communication through the arts, and communication through printed words, do not encompass the same breadth of meaning provided through the tangible aspects of material culture, which includes various objects and structures that visually and physically communicate historical narratives.
