(sorry Garfield!) First of all, molecules have to be bumping around and the words printed on the paper aren’t moving. Also, his skin isn’t semi permeable, which means that it doesn’t allow certain types of molecules to pass through but blocks others. (Note that a semipermeable membrane is not the same as a selectively permeable membrane. Semi-permeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane "chooses" what passes through. (size is not a factor) Second, in order to get the knowledge from the book to his brain, you have to read, which requires energy so it’s not diffusion since diffusion doesn’t use energy, and there is no water, so it can’t be osmosis since there has to be a diffusion of
