Homework Aggregation Pipeline - question

is it correct? Isn’t there missing “” in the B option to be correct and makes sense ? Also there is an empty space extra comparing to answer A, although they are syntactically exactly the same one of them is correct one of them not.
Thank you

Hello azor.haf,

Thanks for the note. Can you post a screenshot of the problem? If you’re talking about Homework: Updates Using Aggregation Pipeline, I don’t think any of the answers are missing a check box.


Hello it is how was my post formatted in this forum, not a check box but
[ and ] in the code seems to be missing in answer B

Maybe I am crazy, but it looks like that the question was changed. Now it seems to be ok.
