Explanation:
A: The whole purpose of an expert system is to look at the data it has to work with and what the user presents to it and to come up with new or different solutions. It basically performs data-mining activities, identifies patterns and relationships the user cant see, and provides solutions. This is the same reason you would go to a human expert. You would give her your information, and she would combine it with the information she knows and give you a solution or advice, which is not necessarily the same data you gave her.
