What is one element that is a key difference between the delivery of a written composition and an auditory speech? 1. eye contact 2. grammar rules 3. fluency 4. persuasive techniques i think it's 2 not to sure

I think it’s 1. Because when you write something/speak you have to use correct grammar, there has to be flow, and persuasion. Eye contact thing is the only you don’t need when writing. Hope it helped! It sounds complicated but I think it’s simple. :)

D. prior knowledge
