Task: Question Answering
Input (English): Passage: My dog is a very large , 180 pound great dane named Walter . Walter is pretty lazy but about 5 times a week he likes to get outside for a while and walk around to take in some interesting smells . On these days , I will usually wait until around 9 am before I tell Walter he is going to get a walk . Once he hears that word he gets incredibly excited and jumps around , almost knocking pictures off of my walls . I have a special harness that allows me to control Walter when he gets excited , but does not choke or hurt him . I walk around a loop in my neighborhood for around 30 minutes before Walter gets tired and wants to go home . After we get back , I give Walter a treat if he was good and prepare his breakfast for him . Question: What did they put on him? Option1: a collar Option2: A harness.
Output (English): A harness.
