Only If

You noted in the S&N lesson that only if introduces neccessary yet here, you allow it to introduce sufficient and apply the same rationale with q6. Could you please explain

Thanks for your question @sonson

I don't see the phrase "only if" appear in question 6. Would you mind clarifying? Thanks!
