What makes someone intelligent?

Intelligence is a word that can be defined as "quick to comprehend" or "able to have a good understanding of something." Being intelligent does not necessarily mean that you already know what makes the sky blue, but that you would understand and remember why it is if someone taught it to you. You are also able to judge a situation and figure out what is going on. I would consider my 5 year old niece to be intelligent. She does not know what 56 divided by 7 is. She doesn't know what the capital of Iowa is, either. Yet she is sharp as knife and notices everything. She can take in a situation and know what is going on. She will meet someone and remember their name without having to prompt you for it. Intelligence is not defined by what you know or how much about it, but by how you grasp things and how you perceive them.
