Final answer:
The letter's organizational pattern is topical, focusing on distinct aspects of the overall topic.
Explanation:
Topical Pattern: The letter from the new dentist office that includes headings like 'Our Dentists,' 'Our Services,' and 'Payment Options' utilizes a topical organizational pattern. In this pattern, main points are developed based on different aspects or subtopics within an overall topic, and the order of presentation doesn't necessarily follow a strict chronological or sequential order.
Example: If you were giving a speech about the services available at your college, such as the library, student development office, and financial aid, organizing it topically allows flexibility in the order of presentation.
