Как по-английски будет предложение : " это была группа из семнадцати учеников не так-ли?"

It was a group of seventeen students, was not it?

Journalist: Hello everybody. Now we are in front of the university from where the group of students was lost yesterday. So now I am going to speak to the headmaster about the lost students. Hello Mrs. White.

Mrs. White: Hello.

Journalist: It was a group of seventeen students, was not it?

Mrs. White: Yes, it was. The police does his best to find our students.

Journalist: We hope the police will find them soon and everything will be alright.

Mrs. White: Yes, we should not lose our hope.
