"If only" is a necessary indicator. Why is "To ensure" in B a sufficient indicator? So confused how sufficient/necessary indicator combos like this can go either way

Hi Capetowner!

If you're faced with a sentence that seems to contain conditional reasoning but it doesn't seem clear how to diagram it out, you could try re-formulating what you're reading into simpler, different language, which could potentially add clarity as to how to diagram the original statement. For example, how would you diagram something like the following: "To ensure you don't get rained on outside, you should bring an umbrella"?
