If I were holding a gun in real life, I'd want something better than mixed reactions, I want reactions of a 12yr old FPS player!

But 75 seems excessive to prove a point, particularly for test questions, that's getting on for 10% of the score. The fuzziness would end you up in a situation arguing that that amount is fair use. If you had an article and had 3 or 4, I would say it'd be pretty clear cut.
