D) Generalization

Q12 (2 points) What is the difference between aggregation and composition?

A) There is no difference

B) In composition, the part cannot exist without the whole; in aggregation, it can

C) Aggregation is stronger than composition

D) Composition is only used for inheritance

Q13 (2 points) In a use case diagram, what does the <> relationship indicate?

B) A filled black circle

C) A circle within a circle

D) A diamond shape

Q19 (2 points) What is a "swimlane" in an activity diagram?

A) A type of decision node

B) A way to group activities performed by the same actor or in a single thread

C) The final state of the diagram

D) A type of message
