Question

For a response to literature, which audience would most likely find an informal writing style appealing?writing class teacherfellow studentscollege review panel

Answer 1

The most appealing audience for an informal writing style are fellow students. 

The reason for this is that fellow students most likely wouldn't mind a more informal style while a college review panel, a writing class, or even a teacher all would most likely mind very much if you wrote something in an informal way, compared to writing it more formally.
