input: Please answer the following: Process:  - Fluid - Waste enters the kidneys - A processing moment in the kidneys let waste and fluid pass - Prevents larger molecules to pass - Fluid goes back to the bloodstream - Bad waste is removed - The final product is turned into urine.  Perturbation hypothesis: suppose you eat fruit happens, how will it affect things would run smoother.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


input: Please answer the following: Process:  - Iron is exposed to oxygen - Is exposed to air - A chemical reaction occurs - The iron starts to oxidize - The iron starts to rust.  Perturbation hypothesis: suppose safe environment for mother bird happens, how will it affect iron is exposed to oxidization.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: no


input: Please answer the following: Process:  - The thermostat senses that the temperature has dropped - A signal is sent to the heating system - Heating oil travels from the tank to the burner - The oil becomes a fine mist mixed with air - The oil/air combination is injected into the burner - The burner is ignited in the combustion chamber - The furnace heats the air - The blower sends the heated air through the ducts - The heated air comes out the vents and into the room.  Perturbation hypothesis: suppose thermostat does not sense tempertaure dorp happens, how will it affect oil travels from tank.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


input: Please answer the following: Process:  - Networks of trees start forming - The trees die off - The dead material provides nutrients for more trees - The rising trees provide shelter - And more organisms begin to thrive - The ecosystem known as a forest is made.  Perturbation hypothesis: suppose less forest formation happens, how will it affect MORE forest formation.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output:
yes
