Abby and Dave had just moved in to their new house. "Let's explore," Abby said. They opened all the closets in the bedrooms. Then they found the door to the attic. Their dad noticed them opening the door. "Go ahead," he said. "It's full of old junk."
In the attic, Abby and Dave saw an old dresser and some boards. Then they noticed a very large metal box. They walked over to look at it more closely.

a: Abby and Dave open thw metal box
