Task: Question Answering
Input (English): Passage: I was late for school the other day because my alarm did not go off . This was very upsetting as I am never late . My alarm did n't go off because the power went out and I did n't have any batteries in the clock as a back up power source . So I realized I needed to change those batteries . Then I opened the back of the alarm clock and looked which direction to place the batteries . Battery compartments always tell you which side is negative and which is positive . Then I place the batteries in the alarm clock . I also have to make sure to set the alarm as well . I make sure to set it an hour before I have to be at school . I test the alarm to make sure the batteries work . Question: What did they click back on? Option1: back of alarm clock Option2: battery
Output (English): back of alarm clock
