Final answer:
Harriet Tubman logically explains the consequences of a runaway returning to the plantation, employing logos to persuade her followers.
Step-by-step explanation:
The passage from Harriet Tubman: Conductor on the Underground Railroad that exemplifies Tubman's use of logos is: "She tried to explain to them why none of them could go back to the plantation. If a runaway returned, he would turn traitor, the master and the overseer would force him to turn traitor." In this excerpt, Tubman employs logical reasoning to persuade her followers that returning to the plantation poses a risk not only to themselves but also to the entire Underground Railroad operation. By logically presenting the consequences of a runaway's return, she evokes a reasoned understanding among those she seeks to protect and lead to freedom.
