Ms.Sue can you check my answers please their down below.
I already did check them and posted my responses to your answers.
But I posted #'s 9 and 20 as well.
I told you I don't know about 9. 20 is wrong, and I posted a website that should help you find the right answer.
Ms.Sue I am really stuck on number 20?

20 is probably D.
