Question 21 of 50 Question 21 3 points Save Answer Shalene Kolchek bought a Great Lakes Spa from Val Porter, a dealer who was selling spas at the state fair. Kolchek signed an installment contract; then Porter and Kolchek arranged for the spa to be delivered and installed the next day. Three months later, Kolchek left her six-year-old daughter, Litisha, alone in the spa. While exploring the spa's hydromassage jets, Litisha stuck her index finger into one of the jet holes and was unable to remove her finger from the jet. Litisha yanked hard, injuring her finger, then panicked and screamed for help. Kolcheck was unable to remove Litisha's finger, and the local police and rescue team were called to assist. After a three-hour operation that included draining the spa, sawing out a section of the spa's plastic molding, and slicing the jet casing, Litisha's finger was freed. Following this procedure, the spa was no longer functional. Litisha was taken to the local emergency room, where she was told that a bone in her finger was broken in two places. What defenses to product liability might Porter or Great Lakes be able to assert? Assumption of risk - Litisha assumed the risk when she put her finger in the jet hole Commonly known danger - everyone knows not to put their fingers in jet holes unless you don't want your finger Knowledgeable user - Litisha was an expert spa user, they've had the spa for 3 months Comparative negligence - Kolchek should not have left her 6 year old unattended in the spa in the first place
