How are audience and genre connected?

The audience you are writing to shapes your entire paper.  "What you write, how much you write, how you phrase it, even your choice of genre (memo,essay,email,note,speech)-all are influenced by

 

the audience you envision"  This states that even the genre you write in is affected by the intended audience.  If you are writing a paper for a teacher in class on a certain book you would probably choose to write an essay to get your points across clearly and organized.  When writing anything you must first consider the audience and then figure out an appropriate genre.
