In the wonderful design of things you secure a B- just for effort and hard work. Exactly where you confused me personally ended up being on all the details. As as the maxim goes, details make or break the argument.. And it could not be more true here. Having said that, let me reveal to you just what exactly did do the job. The text is actually rather convincing and this is probably the reason why I am taking the effort in order to comment. I do not really make it a regular habit of doing that. Next, whilst I can see a jumps in logic you come up with, I am definitely not sure of how you appear to unite the ideas which help to make your final result. For now I shall yield to your point but hope in the future you connect the facts better.
