It’s impossible to tell exactly how tall you will be. Especially since you are already taller than both your parents. Is there any other tall males in your family? You could be as tall as them, otherwise, time will tell. Stay tall :)
I think that the answer is D. Dieting because dieting helps your body eat more things that are good for it and, less things that are bad for it. It can make your skin clearer, and help you feel good overall which is a physical health help trait.
Lol funny question.
But to answer it, yes in order to stop a piece of paper from folding or creasing you put it in a folder, or maybe a binder. You can even lay this piece of paper on a table that won’t be touched/untouched. So therefore it will stay flat and not have any creases or bends or folds. Also a folder keeps the paper clean from getting messy
