Final answer:
Tasha should eliminate the topic of Front Office Sales, as it is less relevant to the role of a medical administrative assistant.
Step-by-step explanation:
Based on the information provided, Tasha needs to eliminate the topic of Front Office Sales from her list of ideas. This is because the other three topics - Customer Service Representatives, Medical Secretary, and Certification - are all directly related to the role of a medical administrative assistant. Front Office Sales, on the other hand, seems to be more focused on sales and may not be as relevant to the job description of a medical administrative assistant.
