Example Input: Question: If Mary is performing an experiment and she increases the frequency of her electromagnetic wave, what happens to the energy it produces? 
 Answer: increases
Example Output: The higher the frequency of an electromagnetic wave, the greater its energy.

Example Input: Question: Derek is diving into the ocean. The pressure at the surface will be light, and the pressure the deeper he goes will be 
 Answer: stronger
Example Output: Pressure: Pressure increases with depth, but increased pressure raises the melting temperature, so melting of rock is less likely to occur at higher pressures.

Example Input: Question: If we keep filling a balloon with oxygen particles what happens to the pressure? 
 Answer: increases
Example Output:
More particles inside the container means more collisions, and more collisions mean a higher pressure.
