Example Input: Question: Joan is trying to get rocks to melt by using depth to get higher pressure. The more pressure that Joan applies to the rock, the melting temperature will be 
 Answer: higher
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: Because of gluons, quarks are attracted each _____ strongly the farther apart they are. 
 Answer: more
Example Output: Gluons make quarks attract each other more strongly the farther apart the quarks get.

Example Input: Question: Eric measures 20 hydrogen ions per 100ml in one solution. Another solution has 30 hydrogen ions per 100ml. The solution with more hydrogen ions is _____ acidic. 
 Answer: more
Example Output:
With a higher concentration of hydrogen ions, a solution is more acidic but has a lower pH.
