Over the course of two days, Carmella heard repeated "pecking" sounds coming from the north side of her three-story house. Toward the end of the second day, she examined the exterior of her house and noticed two large holes located near the roof. To inspect the holes more closely, Carmella used a new extension-style ladder that she purchased recently at a local hardware store. With the ladder extended fully, Carmella climbed to the roof of her house and inspected the holes. She concluded the holes were caused by a woodpecker and decided to conduct some research to identify ways of keeping woodpeckers from damaging her house. As Carmella began to climb down the ladder, it suddenly collapsed causing serious injury to Carmella's right arm and shoulder. What legal advice (available claims/legal theories) would you give to Carmella? Explain
