Task: Question Answering
Input (English): Passage: I adopted a dog from the animal shelter . I purchased for my dog a harness , leash , food , a clicker , and small training treats . I began with simple commands , such as sit and stay . If she did not do the desired behavior , I did nothing . I did n't reprimand her because I wanted to use positive reinforcement . After she learned simple commands , I advanced her to more complicated things , like going into a down position and then urging her to crawl forward while staying down . At first , I lured her with the treat , and clicked her and rewarded her with the treat if she did it . If she stayed down and crawled , I quickly clicked the clicker and rewarded her with the treat . If she did n't do it , I waited a few minutes and tried again . Question: What is  given as a  reward ? Option1: a treat Option2: a belly rub
Output (English): a treat
