Comment on any four of the five scenarios described below. By 'comment', I mean tell me if we have a contract and why. Assume the facts as stated can be proved.... 1. 'I promise to give you my bicycle for $1 at 4pm today". Assume you 'accept'. 2. I promise to give my bicycle at 4pm today". Assume you 'accept'. "3. I promise to sell you the machine gun that my grandfather left me when he died for $60,000 cash, payable at 4pm today".. The machine gun is now on the 'banned weapons list' established by the government. 4. You were shopping at Leon's for a new couch and the clerk, after 15 minutes of back and forth, said to you "Ok, we'll sell you the couch for $600." You said you'd think about, left the store and returned 15 minutes later and said to the clerk "ok, I'll buy it for $600". He replied, "I just sold it." 5. You offer to sell me your car for $12,500. I think that's a pretty good price but it's more than I want to pay. "I'll give you $11,000 cash", I tell you. You respond with an abrupt "no". I then offer the full asking price of $12,500. Do we have a valid contract
