Hello I need help with these past assignment questions

Read the case study below and answer the questions that follow: A deal gone sour A and B enter into a business transaction in terms of which A sells and B buys a horse for R25 000. B pays the agreed amount and the parties agree that B will take delivery of the horse a week from then. At night, A usually locks up his horses in an enclosure near his house. From the day of the sale onwards, A stops locking up the horse that B bought from him and allowed it to roam the fields at night. A day before B is due to come and collect the horse, wild dogs attack and kill the horse. When B arrives to collect his horse, A tells him the sad story about the horse and wild dogs, calling it an 'act of God'. A offers to sell another horse to B, and that he will have to pay for the new horse. B, however, insists that A replaces the dead horse with another, as A's negligence led to the loss of B's horse. A argues that he was under no obligation to look after the horse alter B had bought it.
