premise: Mr Ferdinand Piech said that the German company did not have any confidential plans or documents about GM's ultra-low-cost factory project.
hypothesis: Ferdinand Piech is no longer alive.
reason: It's not clear from the text because we don't know when he said this and no information is provided about his death at all. In actuality, he is dead, but we wouldn't know that without external knowledge. It's difficult because the system probably assumes he must be alive if he "said" something.
