question:
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.

answer:
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")

question:
Question: How many groups were stationed at RAAF Station Pearce in August 1940 when Charlesworth was in command? Passage:As part of the RAAF's reorganisation following the outbreak of World War II in September 1939, No.2 Group was formed in Sydney on 20November; Charlesworth was appointed its Senior Air Staff Officer (SASO). He continued to serve in this position when the group was re-formed as Central Area in March 1940. Posted to Western Australia to take command of RAAF Station Pearce in August, he was promoted to temporary group captain on 1September 1940. He became Senior Administration Officer at the newly established Western Area, Perth, in January the following year. In September 1942, Charlesworth took over No.2 Bombing and Gunnery School in Sale, Victoria. He handed over to Group Captain Charles "Moth" Eaton in August 1943, before briefly taking charge of RAAF Headquarters Forward Echelon in Brisbane. Charlesworth was appointed Air Officer Commanding (AOC) Eastern Area, headquartered at Bradfield Park, Sydney, in December 1943. Eastern Area was responsible for maritime patrol and anti-submarine warfare off the coast of New South Wales and southern Queensland. Japanese submarine activity had decreased in the months prior to Charlesworth taking command, and he was concerned that Allied ships were becoming complacent. He observed "a general slackening off in procedure; ships are seldom where they should be, and a minority of merchant ships identify themselves to aircraft". The RAAF's patrols had also settled into a predictable pattern that would have been easy for an observant submarine captain to avoid.

answer:
Posted to Western Australia to take command of RAAF Station Pearce in August, he was promoted to temporary group captain on 1September 1940

question:
Question: Which album had made the most money for The Who by the year Quadrophenia was released? Passage:The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by destroying guitars and drums on stage. Their first single as the Who, "I Can't Explain", reached the UK topten, and was followed by a string of singles including "My Generation", "Substitute" and "Happy Jack". In 1967, they performed at the Monterey Pop Festival and released the US topten single "I Can See for Miles", while touring extensively. The group's fourth album, 1969's rock opera Tommy, included the single "Pinball Wizard" and was a critical and commercial success. Live appearances at Woodstock and the Isle of Wight Festival, along with the live album Live at Leeds, cemented their reputation as a respected rock act. With their success came increased pressure on lead songwriter Townshend, and the follow-up to Tommy, Lifehouse, was abandoned. Songs from the project made up 1971's Who's Next, which included the hit "Won't Get Fooled Again". The group released the album Quadrophenia in 1973 as a celebration of their mod roots, and oversaw the film adaptation of Tommy in 1975. They continued to tour to large audiences before semi-retiring from live performances at the end of 1976. The release of Who Are You in 1978 was overshadowed by the death of Moon shortly after.

answer:
The group released the album Quadrophenia in 1973 as a celebration of their mod roots, and oversaw the film adaptation of Tommy in 1975
