  • Philippe Beauchamp thinks this is interesting:

23.  In a Class diagram, what does a line with an arrow from one class to another denote?
A. Attribute visibility
B. Class visibility
C. Method visibility
D. Global visibility

Note

What is this question getting at? Visibility isn't mentioned in this chapter in terms of attribute versus method/global... and an arrow like this in a class diagram usually denotes a relationship between classes. Not the attribute visibility that is apparently the correct answer...
