Child Keeper Safety

Im not asking for paragrapha nswers just a thought or two on each question cuz i read the book and i have no idea about these questions
Please help!

1. On page 122, Julia says, “Even if the law says that no one is responsible for anyone else, helping someone who needs it is the right thing to do.” Who understood better how to “help” Kate, Sara or Anna? Explain

2. What is the metaphorical relevance of Brian’s profession as a fire chief?

3. On page 142, Brian says that when rescuing someone from a fire, that “safety of the rescuer is of a higher priority than the safety of the victim. Always.” How does this apply to his role in h is own family?

4. Do you feel that it’s ethical to conceive a child that meets specific genetic requirements?
If not, do you believe that there should be specific exceptions, such as the purpose of saving another person’s life, or is this just a “slippery slope?”
