I need help with these questions please ASAP?

Answer ANY THREE of the following questions: 1) "Contracts must be in writing to be enforceable." Discuss the accuracy of this statement. What is the general rule? A full answer would also discuss at least one exception to the general rule. 2) One of the requirements in a contract is that there must be an exchange of consideration between the parties. Explain what is meant by consideration. Give me an example of consideration. 3) With respect to breached contract damages awarded, discuss the meaning of duty to mitigate. 4) "Signing a guarantee is a mere formality." Comment on this statement. Is this statement true? Your answer should include a comment on the significance of signing a guarantee to liability exposure. 5) If Joe sued Sam for wrongful dismissal and it was established that Joe was not given the proper notice he was entitled to, what are a few of the factors the court would take into consideration in assessing the damages he will be awarded in terms of the common law notice period? Keep your answers short. I suggest 2-4 sentences or bullet points per question should be sufficient. These questions are each worth 2 points on your test - so your response should fully address the question but can be brief
