Also, the listed correct answer "Where used you to work" is bad English in my world...
The usual English patterns with use/used are:
- Where used you to work?
- Where did you use to work? ('did you used to...' would be incorrect here according to Longman's, but others seem to accept it...)
"English Grammar Today" by Cambridge University Press disagrees with your assertion that "used to" is incorrect. And it's the way I've said it for my entire 55 years living in the South East and South of England. http://dictionary.cambridge.org/grammar/british-grammar/past/used-to
Last time I said, 'where did you work', but was marked wrong and told I should've said,'where did you usually work', so this time I wrote that and it said I was wrong again!!
Here are the four possible answers at the moment:- Where did you used to work? where did you use to work? where were you working? Where were you usually working?
Just got marked wrong for "where did you used to work" so this isn't quite right. I thought "arfer" had the idea of "usually" in it somewhere...
Just said "where did you used to work" and was marked wrong. Are you sure all four are accepted?
Apologies, someone had re-edited it and deleted some of these options. They're back now.
Sorry, mcode, I just got wrong for "where did you usually work'". The Gremlins have been at it again.
Thanks for the message, that's been added now. It shows the difficulties of exact translation. :-)
Don't know what happened there, that's put back now, thanks for the comment.
Where did you formerly work? should also be a valid translation I think.
