Input: Question: Where was the jockey born that became Fenomeno's regular rider? Passage 1:On his three-year-old debut, Fenomeno won a minor race over 200 metres at Tokyo on 29 January, beating the subsequent Tenno Sho (autumn) winner Spielberg into second place. He then stepped up in class for the Yayoi Sho (a trial for the Satsuki Sho) at Nakayama and finished sixth of the fifteen runners behind Cosmo Ozora. On 28 April the colt was moved up in distance for the Grade 2 Aoba Sho over 2400 metres at Tokyo and started the 1.1/1 favourite against sixteen opponents. Ridden by Masayoshi Ebina, who became his regular jockey, he recorded his first important success as he came home two and a half lengths clear of Etendard. The colt was then moved into the highest class to contest the Tokyo Yushun on 27 May in which he started at odds of 13.6/1. He was less fancied than Sunday Racing's other two runners World Ace (the favourite) and Deep Brillante with the best of the other runners appearing to be Gold Ship and Grandezza (Spring Stakes). Coming from well off the pace, Fenomeno produced a strong, sustained run on the outside, but just failed to overhaul Deep Brillante and was beaten a nose in a photo finish.
Passage 2:Thado Minbya was born Rahula to Princess Soe Min Kodawgyi of Sagaing and Viceroy Thado Hsinhtein of Tagaung in 1345. From his mother's side, he was a grandson of King Saw Yun, the founder of the Sagaing Kingdom, and nephew of then reigning king Kyaswa as well as a great grandson of King Thihathu of Pinya and King Kyawswa of Pagan. From his father's side, he was descended from a line of hereditary rulers of Tagaung from the House of Thado. According to British colonial period scholarship, his father was an ethnic Shan and his mother was mostly Shan; however some have argued that no extant chronicle or archaeological evidence supports the conjecture. The prince had two younger sisters: Shin Saw Gyi and Saw Omma. His father died soon after the birth of Saw Omma. His mother remarried to Thihapate, a grandnephew of Queen Pwa Saw of Pagan. In 1352, Thihapate became king of Sagaing.
Passage 3:The fight-or-flight response involves nervous impulses which result in hormone secretions into the bloodstream. When a horse reacts to a threat, it may initially "freeze" in preparation to take flight. The fight-or-flight reaction begins in the amygdala, which triggers a neural response in the hypothalamus. The initial reaction is followed by activation of the pituitary gland and secretion of the hormone ACTH. The adrenal gland is activated almost simultaneously and releases the neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline). The release of chemical messengers results in the production of the hormone cortisol, which increases blood pressure and blood sugar, and suppresses the immune system. Catecholamine hormones, such as epinephrine and norepinephrine, facilitate immediate physical reactions associated with a preparation for violent muscular action. The result is a rapid rise in blood pressure, resulting in an increased supply of oxygen and glucose for energy to the brain and skeletal muscles, the most vital organs the horse needs when fleeing from a perceived threat. However, the increased supply of oxygen and glucose to these areas is at the expense of "non-essential" flight organs, such as the skin and abdominal organs.
