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 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 when the dam has not released water recently on water levels decrease at a dam.?

Output: against


Input: Consider Input: Process:  -The thermostat senses that the temperature has dropped -A signal is sent to the heating system -Heating oil travels from the tank to the burner -The oil becomes a fine mist mixed with air -The oil/air combination is injected into the burner -The burner is ignited in the combustion chamber -The furnace heats the air -The blower sends the heated air through the ducts -The heated air comes out the vents and into the room.
 Question: What is the effect of more oxygen in the environment on more heat for the house.?

Output: none
