Example Input: Question: Eric builds a 60ft telescope. Will builds a 10ft telescope. Whose telescope gathers less light? 
 Answer: Will
Example Output: The larger the light collecting area, the more light a telescope gathers and the higher resolution (ability to see fine detail) it has.

Example Input: Question: If Milo is measuring isotopes and he notices that they seem to decay slower then average, what does that mean about the age of the specimen he is examining? 
 Answer: older
Example Output: Because these isotopes decay more slowly, they can be used to date much older specimens.

Example Input: Question: Mike is watching how particles of reactants function, and sees that they are very far apart. Considering that the concentration of them is very low, the chance of them colliding together is 
 Answer: low
Example Output:
At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.
