Definition: 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".

Positive Example 1 -
Input: Process:  -Forest fires burn forests -The animals living in the forest have fewer places to hide -Predators can now find their prey eaiser -Birds will fly away from the area -Waters warm up which hurts the fish swimming in them.
 Question: What is the effect of people are less careful about putting out their campfires on a greater negative effect on animals.?
Output: for

Positive Example 2 -
Input: Process:  -The liver filters blood from the digestive tract -The liver produces bile -The liver produces proteins for blood plasma -The liver converts excess glucose into glycogen for storage -The liver converts ammonia to urea -The liver regulates blood clotting.
 Question: What is the effect of less food intake occurs on more blood plasma available.?
Output: against

Negative Example 1 -
Input: Process:  -An isotope has too many protons -The isotope is unstable -The isotope emits radiation -The isotope decays -The isotope loses some atomic particles -The isotope turns into a different element -The isotope is finished decaying and emitting radiation.
 Question: What is the effect of more exercise opportunity occurs on isotope loses more atomic particles.?
Output: against

Negative Example 2 -
Input: Process:  -Bread is exposed to the elements -Bread absorbs water from the air -Bread absorbs warmth from the air -Dust particles with mold spores fall on bread -Mold spores start to consume the bread for energy -Mold colonies grow until they are visible.
 Question: What is the effect of the bread is kept in a breadbin on the bread will become less palatable.?
Output: for

Now complete the following example -
Input: Process:  -The bird picks a tree -The bird collects twigs and other refuse -The bird makes a flat base with twigs -The bird makes sides with twigs and other things -The bird adds softer material to the inside -The nest is done.
 Question: What is the effect of lower human populations on there are fewer trees.?
Output: 



Answer: against
