Answer to Question 1

FALSE

Answer to Question 2

Inconsistent values are different forms of the same data value. For example, in a database of dog owners and their dogs, we might find a border collie listed as b. collie, collie, border, and border collie. This will create query problems. For example, a query for border collie will not return the dogs listed in the other formats. Or, alternatively, we would have to write a query that includes all possible (or at least known) variations of border collie, and that would be a real pain.
