Final answer:
In 'The Witch of Blackbird Pond,' Mercy manages the children with kindness and empathy. Mercy is not the answer to the second question about Franklin's thirteen virtues; the correct answer is C. mercy, which is not one of his virtues.
Step-by-step explanation:
In "The Witch of Blackbird Pond," Mercy's trait that enables her to manage the children effectively is kindness and empathy. Mercy is characterized by her gentle disposition, as well as her ability to understand and share the feelings of others; these qualities endear her to the children and allow her to teach and guide them with compassion.
Her manner contrasts with an approach based on discipline and strictness or authority and assertiveness. Instead, Mercy exhibits warmth and patience, which are key to her interactions with and management of the children in the story.
As for the second question regarding Franklin's thirteen virtues, mercy is not one of Benjamin Franklin's thirteen virtues as listed in his autobiography.
Franklin's virtues include temperance, silence, order, resolution, frugality, industry, sincerity, justice, moderation, cleanliness, tranquility, chastity, and humility. Therefore, the correct answer to the multiple-choice question is C. mercy.
