Gordon is sitting with a group of his friends outside a public house in a harbour. He says that he will give

100 to anyone who can swim across the harbour. Gordon puts that sum of money on the table to show

the seriousness of his challenge. Chloe is not with Gordon's group but is sitting at the table next to

Gordon. She hears the promise but does not say anything. Suddenly a child falls into the water from the

other side of the harbour. Chloe dives into the water and begins to swim to the child's rescue. As Chloe

approached the child, Gordon shouts out: 'Don't think you are going to get my 100, because I am

withdrawing my offer'. Chloe nonetheless rescues the child and climbs out on to the other side of the

harbour.

Required:

Explain, with reasons, whether Chloe can claim the 100 from Gordon under the law of contract
