Task: Question Answering
Input (English): Passage: I felt like my room was boring and i wanted to add some things I enjoyed . I ordered a poster of my favorite movie character from an online store . The poster arrived in my mailbox after four days of waiting and checking everyday .  There was a tube of sticky putty inside the pack to use when I hung the poster . I placed four dots of the putty on the wall so each corner of my poster would have a dot . The poster had to be hung quickly after placing the putty so the putty would not dry out and lose stickiness .  The poster is on my bedroom door so I see it every morning when I wake up and I can look at it every time I walk out of my room . Question: When did they open the package and unroll the poster? Option1: after picking up from store Option2: after they arrived
Output (English): after they arrived
