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.

Question: If we change resistors in series to not be in parallel the resistance 
 Option1: increases 
 Option2: decreases 
 Explanation: When we add resistors in parallel to each other the total resistance decreases and the current increases.
increases

Question: As the train approached the intersection and blew its horn, expanding the wavelengths of the sound, did the frequency of the horn 
 Option1: increase 
 Option2: decrease? 
 Explanation: This means that as wavelengths get shorter, more waves move past a particular spot in the same amount of time.
decrease?

Question: As the telephone line fell down and the line's resistance went down, the current was 
 Option1: greater 
 Option2: smaller 
 Explanation: We can say that resistance and current in an electric circuit areinversely proportional, because as the one increases, the other decreases, and vice versa.

greater
