Each quiz has 10 multiple-choice questions.

3 rules

4 rules

2 rules

5 rules

Several steps can be directly linked to a immediate succeeding transition through:

AND-junction

structural parallelism

sequence selection

AND-convergence

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

True

False

A source transition does not have any immediate preceding step.

True

False

When a transition is enabled and the associated condition is true, the transition is not cleared.

True
