They lack the kind of structure that【C10】______ us to divide a human utterance into【C11】______　We can change an utterance 【C12】______　one word in it with 　【C13】______　  a good illustration of this is a soldier who can say, e.g., "tanks approaching from the north",【C14】______　who can change one word and say "aircraft approaching from the north" or "tanks approaching from the west"; but a bird has a single alarm cry,【C15】　______ means "danger!"
