Task: Question Answering
Input (English): One evening, I noticed my alarm clock had stopped working, because I had just checked the clock in the living room, and my alarm clock showed a different time. I knew I had to change the batteries. This is important as I need it to wake me up in time for work. I grabbed the clock, turned it upside down and located the slot for the batteries. I lifted the plastic cover and checked what batteries it required: two AA-sized batteries. These are quite common, and I got them from the kitchen drawer. I removed the old batteries by lifting them up, then I placed the new batteries in the same position, making sure the plus-side of the batteries (the little tip) were in the right direction, as it is usually engraved on the plastic. I closed the lid carefully, and the clock started ticking again. I adjusted the time with the help of my watch, and went to bed, knowing I would be woken up by my alarm at the right time the next morning.
Output (English): What did they do to the clock after they put in the new batteries?
