Im so annoyed. Law major here with literally no idea what carcinogenic meant.

Can you EVER infer a conditional statement from a statement about past events?

Say there was this statement "When cavemen have gone out to hunt, they have always brought their sharp rock."

Would this be a conditional statement? If it is about the past?

When there are no indicator words at all, like in the last two examples, is it always subject -> predicate? If not, how would I know what parts of those sentences are sufficient or necessary?

I love the circle diagram! It really helped me understand the actual meaning of sufficient and necessary.
