Final answer:
The purpose of the local ice cream shop's advertisement is to persuade customers to purchase their birthday sundae special by highlighting the natural ingredients and the local accolade of being the tastiest in town.
Step-by-step explanation:
The author's purpose of the ice cream shop advertisement, which highlights that their ice cream is made from all-natural ingredients and was voted the tastiest in town, is to persuade. The goal is to convince the audience to choose their ice cream shop for the birthday sundae special. In marketing and advertising, persuasion is often used to influence customers' decisions, encouraging them to purchase a product or service.
In persuasive writing, a central component is the thesis statement, which clearly articulates the author's position and provides reasons for it. This can be seen in advertisements, where the enticing qualities of a product are presented in a compelling way. The ice cream ad aims to persuade by highlighting their product's natural ingredients and local acclaim, two factors that can sway customers towards choosing their ice cream over competitors'.
