Dr Werner has written an __________________(EXCITE) book about his experiences. In it he says that when he started the experiment he even put on weight.He says: I can't really give an __________________(EXPLAIN) of whats happening to me; perhaps I just believe in my theory. Dr Werners colleagues say that only plants can produce energy from the sun, and they cannot explain how he is able to stay __________________(HEALTH). This case __________________(PROBABLE) needs a lot more research before we will be able to explain it, they say.
