You have to mention duty of care, for duty of care use this case as an example Donoghue v Stevenson(1932) AC 562,also try to find case for a negligent driving, it has to be British case. Mention breach of duty, both elements breach in law and breach in fact. An example cases can be given, but they have to be British cases. Mention causation in fact and use this case Barnett v Chelsea and Kensinghton Hospital Management Committee (1969) 1QB 428. You can add other cases as an example, but as I said they have to be British.
