"The student found the subject."
Translation:Ο μαθητής βρήκε το υποκείμενο.
Oh, am I right in thinking you found this in a "timed practice'? Here is the problem. When we edit sentences the only section that seems to receive the edit is the tree. Other areas such as "strengthen skills, multiple choice etc" don't get the edits. We're working on it.
Thank you for your input. It always helps.
