Shell lesson

The MCQ Exercise 2 (paths to directories, with ls -F ../backup) doesn't seem right. The distraction answer distinguishing between the terminal / and no terminal / (options 2 and 3) is ruled out so long as the correct path is identified. Should the question start the user off with pwd returning User/thing/backup/ as the start location, for a better question?
