Q: Question: Which of the men who attributed the Chronicon to John of Caleto lived the shortest amount of time? Passage 1:Born in Berlin to the distinguished Prussian military family von Bülow, originally from Mecklenburg, he enlisted in the Prussian Army and was assigned to the 2nd Guards regiment of infantry in 1864. He saw action during the Austro-Prussian War in 1866 and gained distinction at Königgrätz. Von Bülow served through the Franco-Prussian War of 1870 as a junior officer, winning the Iron Cross Second Class. A Captain of the German General Staff in 1877, von Bülow was promoted to Colonel and assigned to the 9th Guards Regiment in 1894. In 1897, von Bülow was a major-general and became director of the Central Department in the German War Ministry. In 1900 he was promoted to lieutenant-general and in 1901 was appointed general commanding the Guards Division. He was Commander of the German III Corps from 1903 until his appointment as Inspector of the German 3rd Army in 1912.
 Passage 2:The Chronicon Angliae Petriburgense is a 14th-century chronicle written in Medieval Latin at Peterborough Abbey, England, covering events from 604 to 1368, although the original manuscript ends with an entry for 868, and the remainder was added in the 17th century. It survives as part of a composite manuscript volume held at the British Library with the mark Cotton Claudius A.v, in which it appears on folios 2–45. An edition of the Chronicon was published in 1723 by Joseph Sparke, in a collection of English histories by various writers. According to John Allen Giles, in the preface to his own edition published by the Caxton Society in 1845, the Chronicon was attributed by both Simon Patrick and Henry Wharton to John of Caleto (or "Caux"), who was an abbot of Peterborough (1250–1262). Giles reported a marginal note in the manuscript making a similar attribution, besides a similar note at the beginning of the manuscript stating that it belonged to Peterborough Abbey. However, Giles observed that this manuscript attribution was "comparatively modern", and regarded the chronicle's author as unknown. In Giles's view, the Chronicon is "extremely valuable both on account of the numerous facts which it contains, and for the [700 years] which it embraces."
 Passage 3:Dr. John Rollason (Peter Cushing), his wife, Helen (Maureen Connell), and assistant, Peter Fox (Richard Wattis), are guests of the Lama (Arnold Marlé) of the monastery of Rong-buk while on a botanical expedition to the Himalayas. A second expedition, led by Dr. Tom Friend (Forrest Tucker) accompanied by trapper Ed Shelley (Robert Brown), photographer Andrew McNee (Michael Brill) and Sherpa guide Kusang (Wolfe Morris), arrives at the monastery in search of the legendary Yeti or Abominable Snowman. Rollason, despite the objections of his wife and the Lama, decides to join Friend's expedition. Whereas Rollason is motivated by scientific curiosity to learn more about the creature, Friend seeks fame and fortune and wants to capture a live Yeti and present it to the world's press.
