Final answer:
For increasing brand awareness, minor details like regulatory information or company address are the least important to include in promotions, as they do not contribute significantly to differentiating the product or brand.
Step-by-step explanation:
The goal for Salina in creating greater brand awareness for her company's new line of personal digital assistants would involve emphasizing features that make the product unique, the value it provides to customers, and how it stands out in the marketplace. In terms of promotions, the least important information to include would be any minor details that do not directly contribute to the brand or product identity, such as the standard regulatory information that does not differentiate the product (unless it is a key selling point).
For example, technical compliance marks or the address of the company headquarters might be necessary on product packaging or in certain documents, but they would not typically be focal points for a marketing campaign aimed at increasing brand awareness.
