This question is about "Once Upon a Time"
Answer and Explanation:
1. The blame for the calamity that happened to the child can be placed on the child's parents. That's because parents were driven by racism and irrational fear within the community. They tried so hard to protect their children that they forgot to start protecting them by explaining the dangers that the fence presented, that is, in the hope of protecting, the parents took the danger into the house and did not instruct the child to protect themselves, so we can blame them.
2. The phrase "You have been warned" means that the danger was warned, but the parents ignored it. This is because all the safety devices triggered the alarm, calling the attention of the parents, who ignored and did not pay attention to what was happening.
