What was the primary reason The Twins wanted Zoë to stay with them?

The primary reason The Twins wanted Zoë to stay with them was to help her remember her mom. This reflects their understanding of the emotional and psychological support that memories can provide during times of grief and transition. They believed that by keeping Zoë close, she could maintain a connection to her mother, even in her absence. This choice illustrates the importance of family bonds and the role that memories play in a child's emotional development.

While the other choices present plausible scenarios, they do not capture the essence of The Twins’ intentions as effectively. The desire to give Denny a break, provide financial support, or bond with grandchildren, while meaningful, were not the driving motivations for wanting Zoë to stay with them. The focus on preserving Zöe's memories of her mother is what truly emphasizes the depth of familial love and the responsibility The Twins felt in nurturing her during a difficult time.
