Answer:
Luis is demonstrating Object Permanence .
Explanation:
Object Permanence is a term that describes how a child understands that an object is existing even though the child can no longer see or hear it.
Usually, infants at a certain age do get upset and cry whenever an object has been hidden from them because they are yet to attain the understanding that an object continues to exist even when they can no longer see or hear from it.
On his part, eleven-month-old Luis has reached a stage where he understands that his mom is somewhere close to him even though he can't see or hear from her.
A virtue is a desirable trait that between kindness and cowardice an ethic is like a rule or a decision. To make good or cowardly decisions is what an virtue ethic is. A bad ethic can ruin somebodies with fact that these ethical decisions are made when somebody is in trouble or pain. Good ethics are extreme decsions in protecting the harmed even when it means killing or injuring yourself. My best example would be from the true story turned movie about RED Navy Seals sent to kill an Isis leader and they came across villagers and decided not to kill them because they were young and that cost 3 out of the four men their lives. In the process of dying they saved the fourth dude while aware they were about to kill themselves doing so. Best movies ever! Called Lone Survivor. If there is anything that resembles virtue ethics its what the Arabian guy and his village did to help the lone soldier, putting his life in danger. Hopefully you can summarize off of what I said.
