SECTION I Indicate whether the following statements are true (T) or false (F). Each question is worth 2 points. 1. 'Dynamic Systems' are systems that are mobile and energetic. 2. System dynamics is an approach based on examining complex systems as a whole and the behavior of these systems over time, focusing mainly on the dynamics existing within the system itself. 3. It is necessary to choose the value of At as high as possible, in order to get more accurate results from the simulation. 4. Negative feedback loops make the model more stable. 5. If z affects y negatively, y affects negatively and affects a negatively, then these three variables form a positive feedback loop. SECTION II For the false statements in the previous section, explain why they are false and what the true from should be. This section is worth 10 points
