In this task you will be given a process, and a question. The process contains a sequence of steps that happen in order. The question asks about the effect of a certain event on another event. If the first event has a positive effect on the second event, answer with "for", if it has a negative effect, answer with "against". If there's no causal relationship between the two, answer with "none".

Input: Consider Input: Process:  -Bats and other animals produce a high-pitched tone -The sound travels in waves, as sound does -The sound "bounces" off of a nearby object -The sound wave returns to the bat -The bat hears the echoed sound -Folds in the bat's ear and adaptations in the bat's brain enable it to determine the size, shape, and position of the other object via the properties of the returned sound waves -Other animals use echolocation in generally similar ways -
 Question: What is the effect of the air is in an enclosed airtight area on bats produce a high-pitched tone.?

Output: none


Input: Consider Input: Process:  -Oxygen enters the body through the mouth or nose -The oxygen travels into the lungs -The oxygen binds to hemoglobin proteins within erythrocytes (red blood cells) -The erythrocytes are pumped through the body by the heart -All cells receive the oxygen.
 Question: What is the effect of cells will receive more oxygen on "more oxygen being brought to the bodys cells".?

Output: for


Input: Consider Input: Process:  -A male and female bird mate -The female lays eggs -The eggs are incubated by the parents, by sitting on them, for weeks -The bird hatches from an egg -The parents feed them as the continue to grow -Develop flight feathers -The parents teach them to fly -After learning to fly they leave the nest to live on their own -The next year they breed beginning the cycle again -
 Question: What is the effect of the eggs incubate more safely on less birds.?


Output: against
