As you know, consideration on both sides of a transaction is required in order for a contract to be legally enfoeceable. The following five scenarios are not enforceable contracts because they do not include consideration on at least one side of the transaction. Provide a full explanation about why each one lacks consideration on at least one side of the transaction. Be sure to use proper terminology and to explain your reasoning fully. Assume that all parties are adults with full legal capacity to enter into binding contracts.
a) A husband enters into an agreement with his wife that he will refrain from his use of illegal drugs for at least 6 months and, in return, she will buy him a new motorcycle. Why is this not an enforceable contract?
b) Susan is walking by a park and she sees a child playing in a busy street with a speeding car approaching. Susan rescues the child moments before he is hit by the car. The thankful mother of the child promises to give Susan her diamond earrings in return for saving her child's life. Why is this not an enforceable contract?
