日本語訳を見ると疑問文ではなく否定文です。それとtheyはCambodia's studentsなので主語はthey ではなくCambodia's studentsです。ちなみにCambodia'sはCambodianじゃないでしょうか?
Cambodian students don't have the enough teachers and classrooms.
または、
There are not enough teachers and classrooms for Cambodian students.
冠詞が不確かで違ってたらすみません。
では、Don't Cambodian students have the enough teachers and classrooms?
Do Cambodian students have a short teachers and classrooms?
Aren't there enough teachers and classrooms for Cambodian students?
などなどがあります。
ごめんなさい、日本語訳を間違えました。疑問文です!
