Q: Passage: I was shopping this past weekend and picked up a new painting that I thought would look great in my living room . When I got home I had to figure out exactly what to move around since my walls are pretty full . I figured out a new way to move pictures around until I had a nice empty spot above my couch . I measured the distance between the two hooks on the back of the painting and put small marks on the wall the correct distance apart . I used a level to make sure the second nail was level with the first . When I got it perfectly level I pounded the other nail in the wall . I lifted up the painting and lined up the hooks with the nails and slid the painting onto the nails . The painting looks great above my couch ! Question: What did they pound with the hammer? Option1: Nails to hold the painting. Option2: A hook
A:
Nails to hold the painting.
