           │ > Consider the transition systems of two traffic lights for nonintersecting (i.e., parallel) roads. It is assumed that the traffic lights switch completely independent of each other. For         │
           │ example, the traffic lights may be controlled by pedestrians who would like to cross the road. Model a parallel composition of two traffic lights. Model each traffic light as a simple transition │
           │ system with two states, one state modeling a red light, the other one modeling a green light.  In principle, any form of interlocking of the "actions" of the two traffic lights is possible. For  │
           │ instance, in the initial state where both traffic lights are red, there is a non-deterministic choice between which of the lights turns green. Note that this nondeterminism is descriptive, and   │
           │ does not model a scheduling problem between the traffic lights (although it may seem so). Use the variable names red1, green1, red2 and green 2.                                                   │

           │ > Consider the transition systems of two traffic lights for nonintersecting (i.e., parallel) roads. It is assumed that the traffic lights switch completely independent of each other. For         │
           │ example, the traffic lights may be controlled by pedestrians who would like to cross the road. Model a parallel composition of two traffic lights. Model each traffic light as a simple transition │
