Final answer:
The rhetorical strategy is pathos, which appeals to the audience's emotions to generate sympathy or guilt by highlighting the struggles of families if teenage children cannot work after 7:00 pm.
Step-by-step explanation:
The rhetorical strategy being employed when reading letters from families that would be adversely affected by their teenage children's inability to work outside of the home after 7:00 pm is known as pathos. This strategy appeals to the audience's emotions, aiming to elicit feelings such as sympathy or guilt from the reader.
By sharing the struggles and hardships of the families depicted in the letters, the author seeks to generate an emotional response that may influence the reader's opinion on the subject. Other examples that illustrate the use of pathos include discussing the impacts of not being able to work on the student's ability to support their family.
The difficulty of keeping up with educational demands due to exhaustion, and the lack of parental support and resources. The powerful storytelling encapsulates the everyday struggles of working-class families, framed in a way to make a compelling argument against the restriction of work hours for teenagers.
