You are given a question or fill-in-the-blank question, two answer options (Option1 and Option2) and an Explanation. Your task is to find the correct answer (return the string of the correct option, not option1/2) for the given question from the given options and using explanation.

Ex Input:
Question: If Milo traps gases in a small chamber after having them in a large 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:
increase


Ex Input:
Question: Mary is taking measurements of the amount of oxygen in samples of water. If she measured the total levels of dissolved oxygen in a sample at 70 degrees fahrenheit and compared it to a sample at 80 degrees fahrenheit, which would contain more dissolved oxygen? 
 Option1: 80 degrees fahrenheit 
 Option2: 70 degrees fahrenheit 
 Explanation: Warm water cant hold as much dissolved oxygen as cool water, so an increase in the temperature of water decreases the amount of oxygen it contains.

Ex Output:
70 degrees fahrenheit


Ex Input:
