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:  -A large rocky area is formed -The rocky area has a higher elevation than the surrounding areas -Water from precipitation falls in the area -The water forms a stream -The stream flows towards lower elevation -The stream becomes a river -The river continues to flow along the same path for a long time -The river erodes the rocky area that it touches -The eroded area cuts deeply into the rock.
 Question: What is the effect of more rainy days on bigger river forms.?

Output: for

Input: Consider Input: Process:  -A dam is built in an area prone to flooding -A large amount of rain occurs -The water builds up behind the dam -The dam opens its floodgates when it starts to get full -The water flows into a river below the dam -The dam closes its gates -The dam will occasionally open its gates again to gradually release more water -Eventually all of the floodwater will be slowly released into the river without causing any flood damage.
 Question: What is the effect of water levels rise due to global warming on improved safety from flooding.?


Output: for
