My name is Jane and my father has five daughters. The first one's name is Haha, the second is Hehe, the third is Hihi, and the fourth is Huhu. What do you think is the last daughter's name?
Your father has 5 daughters, 4 of them have names different than yours, Jane. Therefore the last daughter is you, as such, the last daughter's name is Jane.
Good job! You're good at this.
Thank you very much! If you have any further questions, such as the thought process behind my answer, feel free to ask.
