Let's analyze each statement based on the email provided: 1) Sharon's birthday is on Saturday. Answer: F (False). The email mentions that the party is on Saturday night but doesn't state that it's Sharon's birthday. 2) They are going to go buy a birthday cake. Answer: T (True). The email says, "Mum's going to make her special pizza and a birthday cake.", indicating they plan to buy a cake, though not necessarily going to buy it but Mum's going to make one. 3) Sharon is going to decorate the house in the afternoon. Answer: F (False). The email states, "In afternoon, my brother is going to help me decorate the house with streamers." Therefore, Sharon's brother, not Sharon, is decorating the house. 4) Sharon doesn't like rock music. Answer: DS (Doesn't say). The email mentions that Sharon is going to plan the music for the party, but there is no information regarding her preference for rock music or any other genre. 5) The party is going to finish on Sunday morning. Answer: DS (Doesn't say). The email doesn't give any information about when the party will finish, only that Sharon is going to help her Mum clean up on Sunday morning.
