Input: Consider Input: Question: Who is the current president of the instute where Fisher first had a  had a psychotic episode including hallucinations and delusions while working as a psychiatrist? Passage:The co-founder and executive director is Daniel B. Fisher, now a board-certified psychiatrist. A graduate of Princeton University, he completed a PhD in biochemistry at the University of Wisconsin, medical training at George Washington University, and a psychiatric residency at Harvard Medical School. While working as a biomedical researcher at the National Institute of Mental Health before he was a psychiatrist, Fisher had a psychotic episode including hallucinations and delusions. After three months at Bethesda Naval Hospital at age 25, which included forced seclusion and antipsychotic haloperidol, he was discharged with a diagnosis of schizophrenia. He was involuntarily hospitalized three times. He reports being influenced by those who were able to show they cared about the person inside and gave him hope that he might some day recover. He went on to become a psychiatrist. He was told during psychiatric training that "You can’t talk to an illness" but believed that talking to the person inside is a key method for building trust and recovery. He has since worked as a psychiatrist in hospitals and clinics, while also being a part of the consumer movement. He said that a very significant part of the reason for becoming a psychiatrist was wanting to bring to the field what he wished had been there when he was going through psychosis He was a member of the White House Commission on Mental Health, 2002-03.

Input: Consider Input: Question: Who was the leader of Hungary during the Hungarian Revolution of 1848? Passage:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.

Input: Consider Input: Question: Which of the two kingdoms, during which time the term Medjay was used for tribal scouts from Nubia, lasted the longest? Passage:An early recorded use of foreign auxiliaries dates back to Ancient Egypt, the thirteenth century BC, when Pharaoh Ramesses II used 11,000 mercenaries during his battles. A long established foreign corps in the Egyptian forces were the Medjay—a generic term given to tribal scouts and light infantry recruited from Nubia serving from the late period of the Old Kingdom through that of the New Kingdom. Other warriors recruited from outside the borders of Egypt included Libyan, Syrian and Canaanite contingents under the New Kingdom and Sherdens from Sardinia who appear in their distinctive horned helmets on wall paintings as body guards for Ramesses II. Celtic mercenaries were greatly employed in the Greek world (leading to the sack of Delphi and the Celtic settlement of Galatia). The Greek rulers of Ptolemaic Egypt, too, used Celtic mercenaries. Carthage was unique for relying primarily on mercenaries to fight its wars, particularly Gaul and Spanish mercenaries.
