Input: Consider Input: Question: How old was Erwin Ackerknecht when he was excluded from the SAPD in 1937? Passage:Inside the SAPD, the first part of 1937 saw an intensification of differences over attitudes to a possible political party of the united left or a Popular front, and more precisely over the party's approach to the Soviet Union. The differences led to Peter Blachstein's exclusion from the SAPD. Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way"). Blachstein was also affected more directly by the intense political tensions radiating out from Moscow, based on Stalin's suspicions - not entirely unfounded - that there might be comrades in the Soviet Union and further west in Europe who favoured an alternative Soviet leader. The POUM, of which Blachstein was a member, backed a broadly Trotskyite vision for a communist future and its members therefore became targets for Soviet agents. In June 1937 Blachstein was arrested in Barcelona by communist secret police and accused of spying for Franco and working for the Gestapo. With approximately 100 other foreign detainees he was taken to a large garage which had been adapted for use as an ad hoc prison. Because of the appalling hygiene he soon fell ill with Tuberculosis, as a result of which he was transferred to a sanatorium controlled by anarchist comrades. Helped by Spanish friends, in January 1938 he succeeded in escaping back to France.

Output: Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way")

Input: Consider Input: Question: How many casualties were there in the battle in which Haydock was wounded in November 1917? Passage:Haydock was a graduate of Glasgow University and was a travelling salesman for the Clydevale Oil & Colour Company, Bridgeton.

In January 1915, he was commissioned as a second lieutenant in the Cameronians (Scottish Rifles). Haydock saw action at Gallipoli and Palestine before being seriously wounded during an attack on Umbrella Hill during the Third Battle of Gaza on 1 November 1917. He did not return to his battalion until August 1918, after it had been deployed on the Western Front.

He was buried in Bac-du-Sud British Cemetery, Bailleulval.

Input: Consider Input: Question: Which war that Naganari served in was the longest in duration? Passage:As an ensign, Ogasawara served in combat during the First Sino-Japanese War on the cruiser Takachiho at the Battle of the Yalu River. He was subsequently served on the Amagi before transferred to the Navy General Staff Records Department, and assigned to compile an official record of naval operations during the war (which was published in 1903). Ogasawara continued to serve on the General Staff as a naval intelligence officer through the Russo-Japanese War and World War I, rising to the rank of vice admiral by 1918, aside from a one-year tour of sea duty as executive officer of the Chiyoda in 1903, and as captain of the cruiser Tokiwa and battleship Katori in 1912. He was an expert on codes and ciphers, but by the time he had reached flag rank, he was best known as public relations expert for the navy, with his colorful writings on naval history earning him the nickname of the "literary admiral".
Output: As an ensign, Ogasawara served in combat during the First Sino-Japanese War on the cruiser Takachiho at the Battle of the Yalu River
