Answer is in the attachment
1 inch margins, double spaced, name/ subject / period / date ( or how ever your teacher puts them in order) , Page number in upper right hand corner of every page along with your last name before the number of each page, Times New Roman font (12 point typeface)..... you should be able to go into your settings in your word office and be able to set it to MLA format if not i hope this helped.
You use "it's" as a formal Contraction, it's short for 'it is' or 'it has'.
For example, 'it's a wonderful day's
You use "so" when you are describing something
For example, 'it's so hot'
"So" is also another word for "very", which is where the word originally generated. it's often mixed up with "such", but dont worry! you'll learn English alot soon!
