Got only one false and that was because I couldn't resist saying I'm a happy bunny in the conclusion. It helped I just finished a course on basics of propositional logic and First-order logic.
My lack of awareness and attention was unreal. It may be because is 1 am, but it took me about ten minutes to figure out I needed more than 1 jumper and to find them all. Plus a bunch time wasted without checking the celling and floor. this was actually easier than the other, but because of this it took me 17 minutes.
