I wanted to spruce up my house before my team members from work came over for a training. I had three paintings of plumeria flowers waiting to be hung on the wall. These paintings were very special to me. A friend gave them to me. They use to hang in her house that she recently sold. I was happy to receive them and hang them in my house. I first decided which wall would best display the pictures. I picked the wall in the dining room. I put the paintings on the floor at the base of the wall to see how I would space the paintings. I then asked my daughter to hold one painting up so I could measure the distance from the ceiling with a measuring tape. I measure the distance and marked the wall with a pencil. I hammered a nail on the mark and then hung my pictures. 
Question: Why did they hang the painting?
A:
To make their house look nicer
