Question: Last week my friend and I went to the public swimming pool nearby where we live. It was a beautiful day outside - a sunny 80 degrees with not a cloud in sight. When we arrived we found an empty spot and put our towels down, along with the items we brought for the day which included some snacks, suntan lotion, books, drinks, and a change of clothes. There were many people there, including lots of children with their parents and some adults alone or with friends. Shortly after we arrived, we put on suntan lotion and took a dip in the pool. It was just the right temperature. Cool, but not too cold. We swam around for a bit and then got out and laid on our towels for a while. We relaxed in the sun and had a nice chat about what was going on in our lives while we ate some snacks. I then took out my book and began to read while my friend relaxed with her eyes closed for a while. I eventually became tired of reading and went in a dip in the pool by myself for a bit. After a few hours of swimming and relaxing in the sun, it was starting to get late so we decided to head home. We put some warm clothes on in the changing room and headed home for the day.

Answer: How hot was it outside when they went to the pool?

Question: My old fashioned alarm clock did not go off this morning, subsequently I was late for work. I didn't have time to change the batteries so I waited until after work. Once home, I picked up the clock and used a Phillips head screwdriver to open the back of the clock. Using my finger nail I pulled on each of the two batteries from one side until they came loose. I put the dead batteries in the used battery drawer for recycling at a later date. I grabbed two fresh batteries from the adjacent drawer. I popped the batteries, making sure the positive and negatives were properly aligned and I screwed the plate back on with the screwdriver. I had to reset the time which wasn't hard, I just turned the dial on the back until it was correct. I then reset the alarm as well so that I would not be late from oversleeping the next day as well.

Answer:
Why did the batteries need changing?
