I don't really think you can predict exactly because they're all generally the same thing you know what I mean? Last years paper had infancy and development during adulthood for the first question, can't remember the second question and then the third was just general health promotion, the paper before was mostly about adolescence and health promotion aswell. So don't take this for sure but I'm guessing that it might be something on the elderly ( so it will be useful to know physical oremotional changes during this time e.g reduced height due to disc compression or hair turning white/grey due to the pigment losing colour) and again obviously health promotion. I think the second question in the paper is something about factors that affect your health.
But nature v nurture is pretty simple I guess, it's just like whether what makes up our personality is inherited or due to our environment. So like whether people are born aggressive or whether it's something they develop throughout their life due to negative impacts during socialisation for example, listening to abusive language, watching violence in real life or in media (sometimes you can use an example like the James bugler child murderers were believed to be imitating a really violent film)
But for nature/nurture I'd just google the argument and see what people think orrrr go to debate.org they have some good answers on there!
