input: Please answer the following: Process:  - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split - The rocks are now in smaller pieces.  Perturbation hypothesis: suppose more holes in rock surface happens, how will it affect more melting points.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


input: Please answer the following: Process:  - The blood sugar drops in a body - Cells in the pancrease release glucagon - The liver in response turns the glucagon into glucose - And releases it into the blood - The blood sugar levels are restored.  Perturbation hypothesis: suppose eggs are available happens, how will it affect the liver turns more glucagon into glucose.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: no


input: Please answer the following: Process:  - The diaphragm contracts - The lungs expand - Air is pulled from outside the body, into the lungs - The membranes in the lungs collect oxygen molecules - Oxygen is transferred to red blood cells - Red blood cells distribute oxygen throughout the body -   Perturbation hypothesis: suppose "the air isnt breathable" happens, how will it affect there is no breathable air.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


input: Please answer the following: Process:  - Human industry produces chemical compounds - Chemical compounds rise into the air - Chemical compounds mix with elements in clouds - The affected rain falls to the earth - The affected rain can harm natural and man-made objects because of its acidic content.  Perturbation hypothesis: suppose more time occurs happens, how will it affect there are more factories.  Does the supposed perturbation have an effect (direct or indirect) on the process?

output:
no
