Questions and Answers

What is the purpose of auxiliary variables in a model?

  • To represent processes that cause stocks to increase or decrease
  • To measure inflow and outflow
  • To define the boundaries of the model
  • To add model transparency and detail (correct)

Which statement is true about the net flow in a model?

  • Net flow equals inflow minus outflow (correct)
  • Net flow is always equal to the inflow
  • Net flow is unrelated to stocks
  • Net flow is measured in units of length

What do state variables represent in a model?

  • Rates that cause stock changes
  • Memory integrals
  • The current state of the system (correct)
  • Processes that can't be quantified
