I think the hardest job is a chef because cooking takes a lot of time
and especially when there are a lot of people. Moreover, cooking could be dangerous, too. While the easiest job is a fashion designer because it could be fun and I want to be a fashion designer when I grow up.
Thank you for doing your homework, Shinyeong! Please take note of my corrections above.
