Task: Question Answering
Input (English): Passage: I miss my best friend Shelly and so I decided to send her a letter telling her all about my trip to my sister 's house in Alaska , and to also tell her that I hoped she was well . I finished writing my letter and as I went to find a stamp and an envelope I needed to send it , I had found that I did not have any . I went to a store that sells cards and envelopes , and chose a box of pretty purple-colored envelopes to mail my letter in . After that I went to the post office to purchase some stamps that are like small stickers , and chose a heart design that I liked . I only needed one to send the letter but I bought more so that I could send another letter soon if I wanted to . When I got home I filled out the envelope with Shelly 's name and address in the middle , and wrote my sister 's address in the top left corner of the envelope . Now it was ready to be put in the mail and she will receive it in about one week . I drove to the post office and put my letter in the outgoing mail slot . Shelly will be so surprised ! Question: When did they stick the stamp with the heart design on the upper right corner of the envelope? Option1: before mailing the letter Option2: after mailing
Output (English): before mailing the letter
