Me too. This is a listening exercise. Is there any possibility that each time we have to listen a letter, both the letter itself and the full name of the letter are accepted as the correct answer? 'Cuz such kind of problem is not just occurring for once only; it has occurred in quite some other listening exercises such as (for example) the "το γράμμα η" series.
Since we have included every possible combination and single version of each letter many should be accepted. So the problem is what the Duobot decides to choose. There is no way we can influence that mad machine but we are working on a new tree which should bypass these issues.
In the meantime, I suggest you get out of the ABC skill by any means you can --- do not do Strengthen skills for ABCs; it is problematic. I assure you the following skills are really much smoother.
Thanks for your patience. And good luck and happy learning. Any questions you have we will try our best to answer.
This exercise seems to be to translate from Greek to English. Unless you had it from English to Greek in which case you answer would of course be correct.
That's not a real problem. Greek "Rs" are not as strong as Spanish. You'll get used to it.
