Question: I have an important test coming up. So, I've been studying a lot lately. I was studying at the library last night. I set aside four hours to study. But, half way through, my stomach started rumbling. I tried to keep my mind off of it, but my hunger was distracting me from my work. So, I decided to grab something from the vending machine. I stopped studying, and I want to the lounge area of the library. I was surprised by all the great options available. I could choose both hot and cold items. For example, there were tiny sandwiches which could be heated up in a nearby microwave. There were also ice cream sandwiches. I love those frozen treats. I decided, however, just to get some pretzels. I put some change into the vending machine. There were codes for each item available. I entered the code for pretzels into the computer on the side of the machine. And, my pretzels dropped into the bay at the bottom of the machine. I reached into the bay, and I pulled them out. I ate them quickly. They were delicious. I then returned to my homework.

Answer: Why did they decide to use the vending machine?


Question: 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.

Answer:
What did they do to the clock after they put in the new batteries?
