Input: Consider Input: Process:  -Fuel mixes with air -Mix gets inducted into cylinder -Piston compresses the mix -Spark plug emits a spark that ignites it causing combustion -Combustion gases expand -Pushes piston during power stroke -Exhaust valve opens to vent exhaust out tail pipe.
 Question: What is the effect of the engine valves do not get stuck on less power being generated by the engine.?

Output: against


Input: Consider Input: Process:  -Air enters the nose or mouth and travels through the windpipe into the lungs -The lungs have a series of smaller and finer tubes and sacs -Air reaches the smallest and finest air sacs called alveoli -Oxygen travels from the alveoli into the blood -Oxygen-rich blood is carried to the heart -Oxygen-rich blood is pumped throughout the body by the heart -Cells take in the oxygen rich blood and release carbon dioxide rich blood -The carbon dioxide rich blood travels to the lungs -Carbon dioxide travels through the throat and is exhaled.
 Question: What is the effect of deep freeze in area on a greater amount of oxygen being delivered to the blood stream.?

Output: none


Input: Consider Input: Process:  -Water in the clouds becomes very cold -The cold water forms ice crystals -The ice crystals grow by absorbing surrounding water droplets -Form snowflakes -The snowflakes fall to the ground.
 Question: What is the effect of people begin to die off from greenhouse effects so there is less human activity on less snow.?
