Hi, A line of students are walking with A in the lead. They are supposed to walk right behind the person in front of them and keep a consistent distance with each other. But they are walking like the diagram shown below. B, C, F, and G are not in line with A. How do you describe this line? Do you call it a disorderly line? What do you say to ask them to walk in a line? Can I say "Walk in a line"? Thanks.
