Step-by-step explanation:
According to the SMCRE model of communication, the environment of a speaking occasion can be best described through the contextual elements of a rhetorical situation. This encompasses the genre or mode of communication, audience, purpose, context, and culture. Regarding social media as a familiar example, the genre involves different mediums such as messages or posts, while the audience could be real or anticipated. The purpose can range from seeking a good grade to gaining attention or persuading others on online platforms.
The stance represents your viewpoint on the matter being communicated. Context is particularly significant as it refers to the setting which can be influenced by various social, political, or economic factors. Lastly, culture pertains to the shared commonalities among groups that influence communication strategies, considering values, beliefs, and potential cultural conflicts.
