Please answer with T for True and F for False:

1)One way to design adding the primitive objects (e.g. a Line object in the example introduced during the lecture) to the composite is through the composite constructor

2)When using the Decorator design pattern, one primitive object (e.g. a Line object in the example introduced during the lecture) can only be decorated once.

3)The design of Decorator and Composite introduced during the lecture primarily replies on inheritance (subclasses) to achieve their objectives.

4)Sequence diagrams are used to model certain design decisions related to object call sequences. They model the dynamic perspective on a software system as object diagrams do.
