Sorry, David. I didn't ignore your first reply though it seemed so.
I was just having a hard time understanding your reply. I was not sure which was exactly the right meaning for which. So I decided to break up my original questions and ask again in different new questions. Sorry for the trouble and the unhappy feeling the I caused you. Next time I will make my questions clearer and explain things first to avoid any misunderstandings.
My sincere apologies!
