You have to say that after getting all of this information from the head examiner, all of the participants were really surprised and shocked at the same time. Some of them were already aware of those gates and some of them didn't know about them. So you can say that after hearing Allen's questions, many of them become confused because they don't know anything about those gates.
Most likely the head examiner also understands these and because of this he begins to talk about those gates.
[Many of you came from normal words so it was natural that you don't know anything about those gates. Previously there weren't two different worlds in Eden blue. But then suddenly The Spiritual energy began to awaken and everyone living in the hidden blue got rewarded by that.
Sometime later, finally Humans begin to awaken the ability to absorb The Spiritual energy. With that you can say that the first batch of warriors appear on earth.
