premise: I do n't believe anyone knew any better . The cheesecake was one of the first desserts that was eaten up . Ella 's parents had n't wanted this to be a time when everyone brought presents for Ella , so she invited her babysitter over the next day , and that was when we had cake . A slice of the carrot cake served as Ella 's cake . Why did she invite her babysitter over the next day ?
hypothesis: They wanted to make cheesecake and carrot cake both for Ella .
