Final answer:
Hippocrates, the 'father of Western medicine,' is the historical figure who lived during the years 470-377 BC, known for believing diseases had natural causes.
Step-by-step explanation:
The historical figure who lived during the years 470-377 BC is Hippocrates. Hippocrates is renowned as the "father of Western medicine" and was an ancient Greek physician who believed that diseases had natural causes. This contrasts with Dr. John Snow, known as the father of epidemiology, who lived much later, from 1813 to 1858, and is famous for his work in tracing the source of a cholera outbreak in London during the 19th century. In the options provided, a) Dr. John Snow, b) John Graunt, and d) Emile Durkheim all lived in more recent times and are known for their contributions to public health, statistics, and sociology, respectively.
Therefore, the answer to the question, "Which historical figure lived during the years 470-377 BC?" is c) Hippocrates.
