***********************************************
Note:
Almost all of the information I placed here are from compilation of schoolworks which the author/s is/are not indicated so I cannot mention them individually. However, at the back of the book, is a list of its references I placed below (as Default References). The rest, I got from the internet or dictionaries that I indicate as sources.
I am not a know-all in this field. I just read, summarize, and post.
Thanks for visiting!
