"We read them a book."
Translation:Biz onlara bir kitap okuruz.
Late response, but in case anyone else is wondering:
"Okuduk" is past tense (we read). The English is ambiguous when written- simple present or past. Duo will teach "okuduk" later on in the tree, but it accepts it already because it's equally correct.
Duo tries to suggest the "closest" accepted response, which unfortunately may not be the response we were aiming for. :-)
