Wow, you put a bit of work into this post and I must commend you on your effort!
I have to agree with a big macaw on his tweaks of your answers. Some of your answers are spot on, others sorta right and many of your answers are just too vague to be useful in my opinion.
When I have just a bit more free time I will try to add a few alternate answers with a wee bit more specific and useful information.
Please don’t take me wrong, you made an excellent start but hope to add a bit more clarity in some of those answers.
