I would go with B, or Ways to build immunity to diseases. Why? Well, just by using the word biology, we can use process of elimination. The prefix “bio” means life, so C and D already would be out. The suffix “ology” means the study of, so the word biology means the study of life. Because biology often has to do with diseases and finding cures to sustain human life spans, the only logical answer would be B. A would make no sense in terms of biology.

<span>I like to eat potatoes. They are good any way you cook them. My sister likes sweet potatoes. She cooks them all the time for her husband. However, he hates them. When we are together he gives them to me. It is our secret. You have to understand that we can never tell my sister because she would be mad at him if she knew. Her husband doesn't like the secrecy. It is his goal to learn to like sweet potatoes. I think that my sister is beginning to suspect us of something. I think he should tell my sister about the potatoes before she really gets suspicious. He thinks we should keep it to ourselves.
