First, I'm just a student also (a grade 9 student), researching 'bout this kinda topic. This is my assignment in filipino. And I expectedly could find the answer because this is a world wide web that everybody could search their specific kind of questions but i disappointed. There's no answer to this question could find in google. And I am tired cause every type of question in the text bar... There is lot also my fellow students askingggggggggggggggggg.
