Liver failure vs Pancreatic Failure, which patient dies first?

Consider a situation where There is a patient with liver failure and another patients with pancreatic failure. You cannot give any medical assistance to them. Who would die first? This question was proposed by a teacher to me. I'm just a biology student but my teacher is very adamant on the idea that the pancreatic failure patient would die first. I believe otherwise, can someone give me more educated input? Thank you very much
