Chapter 23, Problem 12PQ
CASE STUDY A person in Franklin’s time may have been able to provide the same advice we came up with in Example 23.2. However, an 18th-century person may have had a different reason for his or her advice. What part of that person’s explanation would be the same as ours? What would be different?
