Question: Who managed the team just prior to the current manager? Passage 1:The sympathoadrenal system is a physiological connection between the sympathetic nervous system and the adrenal medulla and is crucial in an organism's physiological response to outside stimuli. When the body receives sensory information, the sympathetic nervous system sends a signal to preganglionic nerve fibers, which activate the adrenal medulla through acetylcholine. Once activated, norepinephrine and epinephrine are released directly into the blood by postganglionic nerve fibers where they act as the bodily mechanism for "fight-or-flight" responses. Because of this, the sympathoadrenal system plays a large role in maintaining glucose levels, sodium levels, blood pressure, and various other metabolic pathways that couple with bodily responses to the environment. During numerous diseased states, such as hypoglycemia or even stress, the body's metabolic processes are skewed. The sympathoadrenal system works to return the body to homeostasis through the activation or inactivation of the adrenal gland. However, more severe disorders of the sympathoadrenal system such as phaeochromocytoma (a tumor on the adrenal medulla) can affect the body's ability to maintain a homeostatic state. In such cases, curative agents such as adrenergic agonists and antagonists are used to modify epinephrine and norepinephrine levels released by the adrenal medulla.
 Passage 2:Petraeus graduated from West Point in 1974. He earned the General George C. Marshall Award as the top graduate of the U.S. Army Command and General Staff College Class of 1983 at Fort Leavenworth, Kansas, receiving a Bachelor of Science degree in Military Science. He subsequently earned an M.P.A. in 1985 and a Ph.D. in international relations in 1987 from Princeton University's Woodrow Wilson School of Public and International Affairs, where he was mentored by Richard H. Ullman. At that time, he also served as an Assistant Professor of International Relations at the U.S. Military Academy from 1985 to 1987. His doctoral dissertation was titled "The American Military and the Lessons of Vietnam: A Study of Military Influence and the Use of Force in the Post-Vietnam Era". He also completed a military fellowship at Georgetown University's Edmund A. Walsh School of Foreign Service in 1994–1995, although he was called away early to serve in Haiti as the Chief of Operations for NATO there in early 1995.
 Passage 3:The 2019–20 season is Port Vale's 108th season of football in the English Football League, and third consecutive season in EFL League Two. It is the first full season under manager John Askey and new owners Carol and Kevin Shanahan. The season covers the period from 1 July 2019 through to 30 June 2020. Askey reshaped the squad by letting 14 players go and bringing in 14 new signings, though David Amoo was the only new player in the starting eleven for the opening game of the season. They lost just one league game in six matches in August, though this was a heavy 5–2 defeat at Grimsby Town, and they also exited the EFL Cup at the first round. September saw them in indifferent form, as they picked up just one league win, though Vale did secure their place in the knockout stages of the EFL Trophy. October saw more promise, as they picked up their first away win, though were held to disappointing draws at home to struggling teams. They went on to claim five wins in six games in the month of November, including a 1–0 victory at local rivals Crewe Alexandra and wins against Milton Keynes Dons and Cheltenham Town in the FA Cup.
