They should be free, because you don't want to be in the middle of shopping, and start your menstrual cycle. Then when you go in the restrooms to get a pad or tampon, they end up being 50 cents each, and with everyone having credit cards, they don't have change anymore. So you end up leaking. And if you're like me, you aren't wearing a shirt that fits, so EVERYONE that walks by sees it. So it'd be a lot easier if the pads and tampons in the restrooms are free.

I would say b.) My mom recommends that he get a cart before going in.
This entire sentence is in present tense and is the only one that makes sense. Hope this helps. :)
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.
