Answer:
Some sentence fragments start with subordinates. Some examples of subordinators are 'when', 'after', 'although', 'before', 'if', 'since', 'until', 'when', 'where', 'while', and 'why'. Sentence fragments can also be phrases.
On the one hand, <u><em>your</em></u> is a possessive and means that something belongs or is related to "you", whoever that subject is. On the other hand, <em><u>you're</u></em> is a contraction. It is short for "you are" that includes the personal pronoun <em>you</em> and the conjugated verb <em>to be</em>. Therefore, the sentence that accurately uses the homophones "your" and "you're" is: Don’t forget to pick up your homework before you leave.
