I'm going through the "la nakamura teorio" course and I'm on section 23 exercise 10 the last exercise of the sector and I'm basically stuck. The exercise wants me to rearrange the sentences into the right order yet it always gets marked as wrong no matter what I do to try change my answer it still gets marked wrong. I don't understand because it's not likely that I could remove the sentence from the list of sentences. So if anyone here has completed course could you like help me out please.
