Good day, the lack of details also made me hesitate in the answer, it was always in my mind that the children were together and in the same place, space.

So it made me hesitate to pick one specifically but obviously the final answer was to grab the first one and then I come back for the second one.

Sometimes the lack of preparation for these events as @galenkp mentions is not so personal, a person prepared for natural disasters or any accident acquires what he has in his environment, that is to say there are nations that have by culture the education of this type and that seems excellent to me, sometimes we are ignorant because of the lack of preparation that comes from our culture. But it is not nice to label people for that either.

The interesting part of the question is with preparation or not, the answer is the same, save the first one you meet.

I liked your comment very much @zeraton
