Translation:He should write
This is the lamest inconsistency/screw-up yet. (Yes, I have reported it. I report every problem I see, but it hasn't seemed to help any.)
Now they make you answer "she has to write". "He has to write" was marked as wrong! I have reported it, but doubt it will be fixed any time soon as the authors seem to have given up on this course.
I don't think it is fair to put it like that. This has been fixed as of 2018-01-12
