History IA on collapse of the Tokugawa Shogunate

So this is my history IA and it was about whether or not the arrival of Commodore Perry in 1853 had more of an impact on the collapse of the Tokugawa Shogunate than the increasing peasant revolts. Keep in mind that this is still old curriculum, but I hope it's helpful. Pre-moderation it got 18/25 (one mark from a 7) and it stayed at 18/25 post-moderation.
