The four see the school principal for the first time at a school assembly.
and it's ten minutes before 
the school assembly.
.ولم يبق سوى عشر دقائق على الاجتماع المدرسي
Und es sind nur noch zehn Minuten
bis zur Schulversammlung.
e mancano dieci minuti all'assemblea scolastica!
e tem 10 minutos para começar
a assembleia na escola.
а до школьного собрания десять минут.
