Example Input: Question: John was combining chemicals in his lab one day. If he were to increase the temperature in his lab, what would happen to the rate of chemical reactions in his experiments? 
 Answer: increase
Example Output: Chemical weathering increases as: Temperature increases: Chemical reactions proceed more rapidly at higher temperatures.

Example Input: Question: Carbon dioxide levels increasing cause the temperature to 
 Answer: increase
Example Output: An increase in greenhouse gases leads to greater greenhouse effect.

Example Input: Question: Quint adds more resistors in a circuit to increase the resistance. The total current in the series circuit 
 Answer: decreases
Example Output:
If we increase the resistance in a series circuit, by adding more resistors, then the total current decreases.
