I understood this question intuitively but I'm trying to practice translating into lawgic so I wrote this out, however, I'm not sure how age would be incorporated. Is this correct? #help

Yasukawa's Conclusion: smaller → better % of survival

Negate Yasukawa's Conclusion: /(smaller → better % of survival)

New conclusion: /smaller and better % of survival OR smaller and /better % of survival

Interested!
