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.

Input: Consider Input: Question: If Milo notices that the frequency of his electromagnetic wave seems to be decreasing, what does that say about the energy of the wave? 
 Option1: it's increasing 
 Option2: it's decreasing 
 Explanation: The higher the frequency of an electromagnetic wave, the greater its energy.

Output: it's decreasing


Input: Consider Input: Question: _____ input force will be needed on an inclined plane with a very steep slope. 
 Option1: more 
 Option2: less 
 Explanation: The more gradual the slope of the inclined plane, the less input force is needed and the greater the mechanical advantage.

Output: more


Input: Consider Input: Question: A wave with a longer wavelength will have a _____ frequency 
 Option1: longer 
 Option2: shorter 
 Explanation: Because all electromagnetic waves travel at the same speed through space, a wave with a shorter wavelength must have a higher frequency, and vice versa.


Output: shorter
