A few points to bear in mind：
Drop a coin and choose whichever side the coin suggests
Dont keep pondering over it. You dont have the time to ponder, and the result of pondering will be no better than a random choice.
Use the three-part and five-paragraph format
First tell people what you want to say, then say it, and finally tell people what you have just said.
Give each of the main paragraphs a topic sentence
The topic sentence tells the reader pointedly what you think. Remember that a topic sentence embodies a debatable statement that calls for support, development or elaboration. It expresses some sort of judgment rather than states hard facts.
Put each option through both of the tests
