Sure. There'll be seven minutes on the first round of questioning. After the first round of questioning, there'll be five minutes allocated to each questioner in the second and subsequent rounds of questioning.
So all that's saying is that in the first round we'd have seven minutes, which we do, and in the second round.... I'll go to it again: “seven minutes for the first round of questioning and thereafter five minutes shall be allocated to each questioner in the second and subsequent rounds”.
