Task: Question Answering
Input (English): passage: Sound waves are created as the air vibrates in response to a person's speech or other sounds. A second person's ear collects these sound waves and converts them into nerve impulses which their brain interprets as sound. In normal speech these waves travel through the air, but with a tin can telephone the waves are transmitted through an additional medium of cups and string.
 question: does a tin can and string really work?
Output (English): Yes
