Final answer:
The provided information does not contain any clear reference to Susan Hummel or how she settled an argument.
Step-by-step explanation:
The question relates to a scenario involving Susan Hummel, however, there is no direct reference to a person by this name in the provided excerpts.
Therefore, it is unclear how Susan Hummel settled the argument, as the information is insufficient to determine a specific event or action taken by such a person.
The excerpts themselves appear to be from different literary sources, including a mention of a courtroom situation and a domestic dispute, but none contain explicit mention of Susan Hummel or her method of resolving an argument.
