Thanks for the detail, Grace. (For your information, the question, "Is it animal, vegetable or mineral?" is the traditional first question in the game, 'Twenty Questions', and it refers to the material of which the object is made. All concrete objects are ultimately composed of one or a combination of these sources. For instance, an iPod is mineral, a shoe is animal -- if it is made of leather, of course -- and a cotton shirt is vegetable.)
