Input: Consider Input: Question: If Mona lowers the temperature on the solution she is creating, what happens to the speed of particles in that solution? 
 Option1: increases 
 Option2: decreases 
 Explanation: At a lower temperature, particles of the medium are moving more slowly, so it takes them longer to transfer the energy of the sound waves.

Output: decreases


Input: Consider Input: Question: The least massive objects have _____ gravity than more massive objects. 
 Option1: higher 
 Option2: lower 
 Explanation: Less massive objects also have less gravity than more massive objects.

Output: lower


Input: Consider Input: Question: Boris was tasked with developing a hypersonic rocket. He built two prototypes that were identical except that they have different gas velocities out of the nozzle. Which rocket was likely the fastest? 
 Option1: the rocket with highest gas velocity 
 Option2: the rocket with lowest gas velocity 
 Explanation: The rocket goes upwards because the hot gases shoot downwards out of the nozzle. The faster the gases go downwards, the faster the rocket goes upwards.


Output: the rocket with highest gas velocity
