What is the main purpose of using System Sequence Diagrams (SSDs) in use case realization?

To visualize the sequence of events that occur during system functionality implementation (correct)
To represent specific object instances and their relationships
To define the preconditions and postconditions of a method
To identify the classes and objects needed for implementing the system functionality

What do preconditions specify in an operation contract?

The conditions that must be true before the operation is executed (correct)
Constraints on the state of the system during method execution
The specific instances of objects and their relationships
The expected state of the system after the method has executed

Which OOA artifact defines the behavior of a method or operation of a class?

Operation Contracts (correct)
Unified Process
State Models
Object Diagrams
