input question: Process: - You breathe oxygen into your body through the nose or mouth - The oxygen travels to the lungs through the windpipe - The air sacs in the lungs send the oxygen into the blood stream - The carbon dioxide in the blood stream is transferred to the air sacs - The lungs expel through the nose or mouth back into the environment.  Question: suppose there is less competition for food happens, how will it affect windpipe is blocked.  - A: more - B: less - C: no effect???
output answer: C

input question: Process: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps - The temperature rises even faster.  Question: suppose less rock carves through the rock happens, how will it affect a GREATER greenhouse effect.  - A: more - B: less - C: no effect???
output answer: C

input question: Process: - Plants and animals long ago died - They are buried under layers of soil - Pressure builds over time - The remains liquefy - The carbon atoms rearrange to become a new substance.  Question: suppose the wind has been blowing more than it ususally does so more sediment has been moved happens, how will it affect more animals and plants die.  - A: more - B: less - C: no effect???
output answer: C

input question: Process: - Coal is burned - Sulfur in the coal combines with oxygen to form sulfur oxides - The sulfur oxides are released into the atmosphere - The sulfides combine with oxygen in the atmosphere to form sulfur trioxide - The sulfur trioxide reacts with water in the atmosphere to form sulfuric acid, a very strong acid - The sulfuric acid makes the rain acidic -   Question: suppose there is less coal available happens, how will it affect LESS acid rain.  - A: more - B: less - C: no effect???
output answer:
A
