Answer to Question 1

A sequence diagram represents the interaction between objects, or between actors and objects ordered in time. A sequence diagram is composed of a timeline, objects that interact across this timeline, and the messages that they exchange. A sequence diagram is basically a space-time matrix for interactions. Two axes contain the diagram: the vertical axis is a timeline, or a chronology of events; the horizontal access identifies the space and the actions that take place within the space. Movement on the timeline axis is one way, but movement on the space axis is bidirectional.

Answer to Question 2

D
