Problem: Background: Josef Mengele (German: ['jo:zef 'meNG@l@]; 16 March 1911 - 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. Mengele was a member of the team of doctors responsible for the selection of victims to be killed in the gas chambers and for performing deadly human experiments on prisoners.
Context: The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people. Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered inferior to the Aryan master race.  Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjager (mountain infantry) and was called up for service in the Wehrmacht (German armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmfuhrer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS-Rasse- und Siedlungshauptamt (SS Race and Resettlement Main Office) in Posen, evaluating candidates for Germanisation.  In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross Second Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. He rescued two German soldiers from a burning tank and was awarded the Iron Cross First Class, as well as the Wound Badge in Black and the Medal for the Care of the German People. He was seriously wounded in action near Rostov-on-Don in mid-1942, and was declared unfit for further active service. After recovery, he was transferred to the Race and Resettlement Office in Berlin. He also resumed his association with von Verschuer, who was at the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmfuhrer (captain) in April 1943.
Question: What was his rank?
Answer: he served with the rank of SS-Untersturmfuhrer (second lieutenant) in a medical reserve battalion until November 1940.

Problem: Background: "Sympathy for the Devil" is a samba rock song by the Rolling Stones, written by Mick Jagger and Keith Richards. Sung by Jagger, the song refers to the Devil, written in the first-person narrative, recounting atrocities committed throughout the history of humanity as if they were somehow "inspired" (or at least witnessed) by him. Although it has been deemed by some as "a homage", in reality, no admiration (or even sympathy, for that matter) is declared for the Devil in the song -other than his "own" request. It is performed in a rock arrangement with a samba rhythm, first appearing as the opening track on their 1968 album Beggars Banquet.
Context: The recording of "Sympathy for the Devil" began at London's Olympic Sound Studios on 4 June 1968 and continued into the next day; overdubs were done on 8, 9 and 10 June. Personnel included on the recording include Nicky Hopkins on piano, Rocky Dijon on congas and Bill Wyman on maracas. Marianne Faithfull, Anita Pallenberg, Brian Jones, Charlie Watts, producer Jimmy Miller, Wyman and Richards performed backup vocals, singing the "woo woos". Richards plays bass on the original recording, and also electric guitar. Brian Jones plays a mostly mixed out acoustic guitar, although in isolated tracks of the studio cut, it is audible playing along with the piano.  In the 2003 book According to the Rolling Stones, Watts commented:  "Sympathy" was one of those sort of songs where we tried everything. The first time I ever heard the song was when Mick was playing it at the front door of a house I lived at in Sussex ... He played it entirely on his own ... and it was fantastic. We had a go at loads of different ways of playing it; in the end I just played a jazz Latin feel in the style of Kenny Clarke would have played on "A Night in Tunisia" - not the actual rhythm he played, but the same styling.  On the overall power of the song, Jagger continued in Rolling Stone:  It has a very hypnotic groove, a samba, which has a tremendous hypnotic power, rather like good dance music. It doesn't speed up or slow down. It keeps this constant groove. Plus, the actual samba rhythm is a great one to sing on, but it is also got some other suggestions in it, an undercurrent of being primitive--because it is a primitive African, South American, Afro-whatever-you-call-that rhythm (candomble). So to white people, it has a very sinister thing about it. But forgetting the cultural colors, it is a very good vehicle for producing a powerful piece. It becomes less pretentious because it is a very unpretentious groove. If it had been done as a ballad, it wouldn't have been as good.
