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 .

Question: Why did she invite her babysitter over the next day ?
Answer: None of the above choices .They wanted to make cheesecake and carrot cake both for Ella .They wanted Ella to have a small private party .There were too many people who wanted to come to Ella 's party .
