Hey there,
Question states: What are possible ways to prevent cancer? check all that apply.
Your correct answer is D.) Live in a warm, dry climate. The reason why I say this would be because cancer would be used to be in the opposite climate of being warm and in a dry climate. These actually decreases any cases of cancer. I was going to say that the answer is C.) but . . . .Just because you visit a doctor, doesn't mean that it's going to prevent you from that. So, this would leave your answer to be "live in a warm, dry climate".
Your clarified answer would be: [tex]\boxed{live \ in \ a \ warm, \ dry \ climate}[/tex]
Hope this helps.
