Yes, that's reason, because the result of an implicit casting of '-' is zero
SELECT 6 + 1 + '-'So if you substitute the '-' with something clearly a string like 'a', you get a conversion failed message.
My first thought was that the correct answer would have been the conversion failed because of the dash. When it was not in the options of possible answers, I guessed incorrectly with the 6-1. Always nice to learn something new.
