Final answer:
The quotation should be placed before sentence 1, introducing Asclepius's relevance to medicine and setting the stage for the paragraph's focus on health and hygiene.
Step-by-step explanation:
The quotation should be placed before sentence 1 to effectively introduce the topic that will be developed in the paragraph. This positioning provides context for the subsequent sentences about Asclepius, his relevance to medicine, and his representation through the Rod of Asclepius, where the snake is a symbol of healing and medicine. Starting with the expert quote sets the stage for the historical and mythical discussion that follows. Additionally, it establishes the importance of Asclepius and his associated symbols in the realm of health and hygiene from the outset, making the paragraph's development more coherent and meaningful.
