True or False: In practice, there is always a perfectly clear-cut distinction between fault repair, environmental adaptation, and functionality addition, with no overlap between the categories.

Correct Answer

False

Explanation

In practice, there is no clear-cut distinction between these types of maintenance. When you adapt a system to a new environment, you may also add functionality to exploit new environmental features, and fixing a fault discovered through unanticipated use may also involve accommodating a new way of working.
