It's not gramatically correct english sentence :/
I know most of us just want it to be accepted, but consider that the course creators have to include all possible alternatives by themselves, it's not operated by AI or so.
I put - I go early to work every day. I think this should have been accepted. Both phrases are equally ambiguous as to whether the person is going earlier than the work start time or just going early in the day (for a day job)
