Example Input: Question: John was playing with alkanes in his lab. If he increased the amount of carbon atoms in an alkane, what would happen to the boiling point of that alkane? 
 Answer: increase
Example Output: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.

Example Input: Question: Milo was moving some metal balls around. If he were to move the balls closer together, what would happen to the force of gravity?
