Example Input: Question: Who is the oldest member of Jan Kuehnemund's band? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

Example Input: Question: How many people died at the camp at Nordhausen? Passage:Sachnowitz was one of 772 Jews to be deported to Auschwitz. He was arrested together with other men in the family on 26 October 1942. Sheriff Gran in Stokke arrested them and sent them to Berg concentration camp. The deportation to Germany happened on the German transport ship in November 1942. Only 34 of the deported Jews survived the stay in Auschwitz and the other concentration camps. Sachnowitz attended the death march from the camp in Buna on 18 January 1945, and they walked 80 km the first day. He estimated that his group consisted of up to 100,000 prisoners, most of whom died under the march. From Gliwice they were sent with train which went all over the present-day Czech republic and Austria and finally arrived in the camp at Dora at Nordhausen after approximately 10 days. The prisoners at Dora and Buchenwald worked in underground factories with building V-1 flying bombs and V-2 rockets. Sachnowitz was a witness of the many bodies, which each only weighed 35–40 kg, which were burnt outside the camp in huge fires or sent to the crematorium at Buchenwald. From Dora Sachnowitz and his comrades were sent by foot to Bergen-Belsen. Sachnowitz was at the end of the war transferred to Bergen-Belsen, which was freed by British forces. Sachnowitz was the only surviving Norwegian in Bergen-Belsen and he was on 28 April 1945 evacuated together with other prisoners to a hospital in Eindhoven. From there he was sent to a hospital in Copenhagen, Denmark, and received proper treatment.
