Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
One example: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
Solution is here: In what year did francis, duke of anjou leave the netherlands?
Explanation: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this: BACKGROUND Fractionated plasma separation and absorption (FPSA) is an extracorporeal liver support method that detoxifies accumulated toxins. There are limited data of its use in the treatment of Amanita phalloides intoxication. The objective of this study was to investigate whether FPSA before liver transplantation improves patients' short-term post liver transplantation survival in Amanita phalloides poisoning. MATERIAL AND METHODS The study population consisted of ten patients who had liver transplantation (LT) due to acute liver failure (ALF) caused by Amanita phalloides poisoning. Six patients were treated with FPSA before liver transplantation. All the patients who were started on FPSA were also placed on the liver transplantation list according to emergent liver transplantation criteria. RESULTS Patients treated with FPSA were in a more severe clinical condition presenting in higher mean MELD, total bilirubin, INR and ammonia along with more frequent hypoglycemia and hepatic encephalopathy grade 3/4. FPSA group had longer mean waiting time on the recipient list (3.5 vs. 1.25 days) but inferior thirty-day survival rate (16.5% vs. 100%). CONCLUSIONS When conservative medical modalities are ineffective, the only treatment for Amanita phalloides poisoning is a liver transplant. Although FPSA treated patients had inferior post-LT survival, FPSA was found to prolong the pre surgical waiting time for critically ill patients, consequently giving a chance of life-saving procedure.
