Answer:
1. Kate cannot sue United based on negligence, which is the duty of care. United was not negligent and owed no duty of care in this instance to Kate.
2. Kate can rather sue based on a breach of warranty. There was a warranty (a written specific guarantee) on the mattress label, which indicated that it was "flame resistant."
Step-by-step explanation:
A warranty, in this case, involves the written statement or claim by United Mattress Co. that the mattress was "flame resistant." United could have limited its liability for breach of a warranty by indicating clearly that the mattress could only slow the flaming process instead of just resisting flame. By making the onerous claim that the mattress was "flame resistant," United was exposing itself to liability claims by Kate, who was clearly negligent in putting a candle near her mattress while sleeping.
