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".

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.?

Process:  -Particles in the environment interact with rocks -The particles remove small pieces of the rock each time they touch the rocks -The particles continue to hit, brush against, or grow against the rocks -The rock eventually is broken apart by this contact -The pieces of the rock are now small rocks -The rock pieces are worn away into smaller and smaller pieces by the same forces -
 Question: What is the effect of erosion rate is greater on rocks move slower.?

against
