Why "This man is young" is not accepted?
Tento muž vs Ten/Tamten muž 'this man' vs 'that man'
Och, OK. Thank you. I guess I was misled by Polish "ten" (this) vs. "tamten" (that).
Why is "That man's young" not right?
The English contractions that are or are not accepted are determined centrally by Duolingo HQ. They apparently do not accept this one.
