Example Input: Question: Mona is excavating a deep tunnel as part of an exploratory committee. As she bores deeper in to the Earth, what can she expect will happen to the temperature? 
 Answer: increase
Example Output: Temperature increases with depth inside the Earth, so melting of rocks is more likely to occur at greater depths.

Example Input: Question: If Mona's country normally emits not a lot of greenhouse gas, but one day decides to raise the amount they emit, what will happen to the global temperature? 
 Answer: increase
Example Output: A decrease in greenhouse gas levels decreases global temperature and an increase raises global temperature.

Example Input: Question: If Mary is running and race and begins to breathe hard, what happens to the air pressure in her lungs as she expands her chest?

Exhaling, or breathing out, decreases the size of the chest, which increases air pressure inside the lungs.
