Task: Question Answering
Input (English): Passage: I had to give a presentation at school about a subject involving cooking or something in the kitchen . I had chose " Safety in the Kitchen " as my subject and had done my research already . My presentation involved having some illustrations the class could see as I discussed my subject , so I had glued all my illustrations to three poster boards . I arrived at the class carrying all three of the poster boards I had prepared . My best friend carried the easel , as it all all too much for me to carry by myself in one trip . We waited at the back of the room until it was my turn to speak . them my friend set up the easel at the front of the room , and I arranged my poster boards on it in the order I would need them . At the end , I asked if anyone had any questions . Then , I picked up my poster boards , my friend picked up the easel , and we took them down from the front of the class . I got a good grade for my presentation . Question: When did they set them on? Option1: When  the easel was on the ground. Option2: After the easel was set up.
Output (English): After the easel was set up.
