This question already has an answer here:
So, I just wrote down the following sentence.
'Now my attempt is to understand the cause of such behaviour. Is it the childhood experiences, as we find in the movie?'
I'm not sure if I've got the punctuation correct in the last sentence with the use of question mark. If reading out, you'd expect the speaker to take a pause after 'experiences' and then provide more information. However, 'as we find in the movie' isn't really an interrogative so putting the question market after it seems erroneous. Kindly suggest the correct punctuation.
