Problem:Question: What was the middle name of the Abwehr Chief who admired the Brandenburgers? Passage 1:During the spring 1940 , the Brandenburg units proved essential in seizing "vital points ahead of Guderian's panzers." On May 8, 1940, the men of the 4th company led by Leutnant Walther crossed the Dutch border wearing uniforms of the Dutch police and arrived two days later. When the Wehrmacht began operations at the bridge Meuse of Gennep, they realised that the Dutch had previously rigged it with explosives to prevent its use by the Germans, however overall there were no issues, Walther's group, pretending to escort German prisoners, took the guards by surprise from one side of the bridge and after a brief confrontation three Germans were wounded and the platoon took possession of the station; the Dutch guards on the other side of the bridge in a confused scramble, left the Germans too close to their objective, and they had no difficulty completing the conquest of the bridge, on which the Wehrmacht tanks passed shortly afterwards. At the same time, other Brandenburg units seized several bridges over the Juliana Canal—also in the Netherlands, while their fellow soldiers entered Luxembourg, occupying bridges over the Our (river) and in Belgium carrying out similar actions. Chronicling Brandenburger No. 3 Company's penetration into Belgium, Lahousen was gratified to report that, "forty-two out of sixty-one objectives were secured and handed over to the units following behind." For their exploits in Belgium and the Netherlands, the Brandenburgers were among the most decorated units marching with the invading German armies, which earned them the admiration of the Abwehr Chief, Wilhelm Canaris. On 27 May 1940, chief-of-staff of the High Command of the German armed forces, Wilhelm Keitel, wrote to Canaris that the Brandenburgers had "fought outstandingly well" which was further validated when Hitler presented Iron Cross commendations to 75 percent of the 600 men who participated. By October 1940, the Brandenburgers constituted an entire regiment-sized unit.
 Passage 2:Gimbel was born on November 16, 1927 in Brooklyn, New York, the son of Lottie (Nass) and businessman Morris Gimbel. His parents were Austrian Jewish immigrants. Gimbel was self-taught in music and following initial employment with music publisher David Blum, progressed to become a contract songwriter with Edwin H. Morris Music. Small successes and moderate fame came as a result of lively novelty songs "Ricochet", which was popularized in a 1953 recording by Teresa Brewer from which was developed the 1954 Judy Canova film Ricochet Romance, and "A Whale of a Tale", sung by Kirk Douglas in another 1954 production, Disney's 20,000 Leagues Under the Sea. Greater success was earned with Dean Martin's recording of "Sway", which reached #6 on the UK Singles Chart, followed by his first big success, Andy Williams' rendition of "Canadian Sunset", which scored to #1 in 1956.
 Passage 3:Donald Duck rose to fame with his comedic roles in animated cartoons. Donald's first appearance was in 1934 in The Wise Little Hen, but it was his second appearance in Orphan's Benefit which introduced him as a temperamental comic foil to Mickey Mouse. Throughout the next two decades, Donald appeared in over 150 theatrical films, several of which were recognized at the Academy Awards. In the 1930s, he typically appeared as part of a comic trio with Mickey and Goofy and was given his own film series in 1937 starting with Don Donald. These films introduced Donald's love interest Daisy Duck and often included his three nephews Huey, Dewey, and Louie. After the 1956 film Chips Ahoy, Donald appeared primarily in educational films before eventually returning to theatrical animation in Mickey's Christmas Carol (1983). His most recent appearance in a theatrical film was 1999's Fantasia 2000. Donald has also appeared in direct-to-video features such as  (2004), television series such as Mickey Mouse Clubhouse (2006–2016), and video games such as QuackShot (1991).
