Please, can you tell me this word left means what in this sentence? Thanks for you help. This is context below. When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. 　　 It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions. 　 When it is eating normally, its own training begins. 　----------------------------------------------- The second sentence I have a problem. I have no idea about left, what does this word means?
