TASK 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".
PROBLEM: Process:  -People breathe and expel carbon dioxide -Engines produce carbon dioxide -Living things produce waste -Waste decomposes -Decomposition produces methane -Water evaporates -Water vapor joins the atmosphere -Carbon dioxide, water vapor and methane are greenhouse gases -
 Question: What is the effect of more people breathe on more carbon dioxide.?

SOLUTION: against

PROBLEM: Process:  -Greenhouse gases are released into the air by human activities -The earth changes energy from the sun into heat -Heat rises from the ground -Greenhouse gas molecules in the atmosphere prevent the heat from going into space -The temperature of the earth increases -The temperature continues to rise and melts the polar ice caps -The temperature rises even faster.
 Question: What is the effect of More greenhouse gases are produced on polar  ice caps are getting bigger.?

SOLUTION: against

PROBLEM: Process:  -Stars burn mass -The star burns until it runs out of fuel -The star can no longer support its weight -The layers of hydrogen press down on the core -The core gets smaller and smaller under the pressure -The pressure causes gravity to get stronger -The gravity becomes so powerful that nothing can escape it -Anything that gets close to it, is drawn into it by its gravity -Light is drawn into it -Light can not escape -
 Question: What is the effect of fewer stars burn on less light can escape.?

SOLUTION:
against
