"The final contest."
Translation:Ο τελικός διαγωνισμός.
You're welcome. Oh I do understand your concern on this one. There are a lot of reports about interchangeable words, where learners are confused about why one is not accepted even though it exists in the hints. We all know though that are exceptions. There are words that are interchangeable in most cases, but not all of them, and those cases are not clarified in dictionaries, or the hints. But that's definitely a language thing. Habit, experience and time resolve these matters.^.^
