In preparation for a mountain-climbing expedition, Alper purchased the necessary climbing equipment from Outfitters, Inc., a retail dealer in sporting goods. A week later, Alper fell from a rock face when a safety device he had purchased from Outfitters malfunctioned because of a defect in its manufacture. Thereafter, Rollins was severely injured when he tried to reach and give assistance to Alper on the ledge to which Alper had fallen. Rollins's injury was not caused by any fault on his own part. If Rollins brings an action against Outfitters, Inc., to recover damages for his injuries, will Rollins prevail? 
No, unless Outfitters could have discovered the defect by a reasonable inspection of the safety device.  No, because Rollins did not rely on the representation of safety implied from the sale of the safety device by Outfitters.  Yes, unless Alper was negligent in failing to test the safety device.  Yes, because injury to a person in Rollins's position was foreseeable if the safety device failed.
