"Our brother-in-law is finishing his book."
Translation:Notre beau-frère termine son livre.
notre beau-frere est en train de terminer son livre what is wrong with this sentence? ... the English is... he is finishing his book... in French... how would you put it otherwise? if the above translation is wrong ... for: he is.... f I n I s h I n g his book versus he finishes his book.... I would like to suggest that in the marking... which ever way one uses the English present tense... ( example: he finishes... or he is finishing....) should be accepted... otherwise you would have to become more precise in distinguishing the both forms of present tense... if sometimes it is accepted what you translate ( whatever form you are using) and sometimes it is not. then you think to yourself.... well, I need to be more accurate.... but then when you are... like in the above example, it still is getting marked wrong.,
être en train de means to be in the process of doing something at that precise moment. There is no inference that to this in the given sentence. In fact, to finish something as arduous, and time-consuming as authoring a book, may take several days if not weeks or more.
A bit of advice. Please write defined sentences using full-stops, capitals to begin the next sentence and paragraphs to delineate your thoughts. Your post are like a stream of consciousness and are extremely difficult to read and understand. Merci.

But I doubt there's any explicit reference giving rise to such an inference in basically any sentence (cases where it's certainly not the case seem far more likely in general). Yet, as one can see, for example, in contributor commeunetexane's recent post "être en train de" is one of the translations that they're aiming to include (implicitly for the English present progressive) with a fairly high level of generality.
My conclusion: the est en train de translation just hasn't been included for this sentence yet. After all, it appears to only have been added to the course a week ago. Whether or not the "is finishing" meets the threshold of "être en train de" every time, it presumably does sometimes, which is the relevant threshold.
In English (in my dialect at least) this sentence isn't restricted to authoring a book anyway; he could just be finishing reading it.
I know where you are coming from but in sentences like
Je suis en train d'appeler mon fils and Il est en train de manger, we do know the action is taking place right now. However, an author (or reader for that matter) can be "finishing" his/her book forever (if you know what I mean). I just don't think the present progressive belongs in this particular sentence. :-)
