Ex Input:
Question: Katie is rubbing her hands on her leg. One hand rubs fast, the other hand rubs slow. The hand that will be cooler in the end is the one that moves 
 Option1: faster 
 Option2: slower 
 Explanation: Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer.

Ex Output:
slower


Ex Input:
Question: If Milo traps gases in a large chamber after having them in a small chamber, what will happen to the rate of collisions between gas particles? 
 Option1: increase 
 Option2: decrease 
 Explanation: This means the rate of diffusion is much slower in liquids than in gases, because the particles of a gas are further apart and collide much less.

Ex Output:

decrease
