"It is a plate of rice."
Translation:Es un plato de arroz.
Hello. I am just a beginner myself but I think you have to look at it more fundamentally, as in a plate of rice is just a plate of rice, and it will never be anything else. Yes the rice may get eaten and disappear but that is not what they mean by temporary. By temporary they mean that the actual state of being can change, such as today I am sick with a cold, but when I get over my cold I will again be healthy. Does that help? I have had to look this up so many times already and still can't seem to retain when to use which verb :) !
