Task: Question Answering
Input (English): Passage: When I was at camp last summer , I was n't allowed to use email , so I had to write a letter to my parents to tell them that I wanted to come home . I sat on my bunk with my notebook propped against my knees and thought about what I wanted to say . After a few minutes , I decided I knew what I wanted to say , so I picked up my pen and started moving it across the paper . Then I wrote `` Dear Mom and Dad '' on the first line . I kept writing all the words I needed to use in order to convince my parents to let me come home . Then I signed the letter with my name . I folded the letter in half and then folded it in half again so that it would fit in an envelope . I taped the envelope shut . Then I stuck a stamp on the upper right corner of the envelope . I wrote my parent 's address on the middle of the envelope and then I walked to the camp office and gave my letter to the secretary so she could mail it for me . Question: This person puts what in the upper right hand corner? Option1: a stamp Option2: The address
Output (English): a stamp
