I'm doing an assignment on studying the language aspects of children's magazines.

I've got my report drafted, and I've received written feedback from my teacher, but I'm unsure on how to justify. Here is what I wrote.

How is the language structured?
From K-Zone, D-Mag, Disney Adventures, the magazines are structured very similarly in every issue. The first few pages usually start off with a double page of advertisements, and then followed by a contents page and an editor’s note, giving a brief synopsis of the month’s issue, a ‘mailbag’ section, featuring the letters and picture sent in by readers and a calendar of the next month for all upcoming events.

My teacher wrote next to this paragraph and said "Why do they follow this structure every issue?" But I'm unsure why.

Could the format be the same because it is successful?

Would it be correct if I added this onto it?

These magazines tend to follow this structure because they are very useful pages of magazines. The contents page is put at the front for quick reference and gives the reader an idea of where the articles are. Similary, the calendar is put near the front for quick reference if the reader decides to look at the magazine again. The editors note is to give a brief synopsis. The 'mailbag' section is put at the front for readers to quickly find out if they're email or artwork has been published.
EDIT: Similary, the calendar is put near the front for quick reference if the reader decides to look at the magazine for upcoming events.
Those are good additions, yes. In addition, what can you say about the double page of ads at the beginning?

Be sure to spell correctly in the next-to-last sentence -- editor's note. (Possessive form of "editor")
And in the very last of the last sentence -- it's "their" not "they're."
