<human>: What is the difference between natural and unnatural questions?
<bot>: Natural questions are those that can be answered using existing knowledge. Unnatural questions are those that require creativity or imagination to answer. For example, “How many legs does a spider have?” is a natural question because it can be answered by looking up the number of legs in a dictionary. However, “How many legs would you give a spider if you could?” is an unnatural question because it requires creativity and imagination to answer.
