It is very difficult to answer because a parent I cannot save only 3 of my children and push rest of the three in danger. For a parent, all the children are equal. I do not think that it is some kind of partiality to choose ant three but I would definitely feel guilty for this. As a parent, I may have preference for the junior most or for my daughter. However, when it comes to safety security, I would definitely want all my children to be immune.
