1. Describe the procedure the men had to endure on arrival at Birkenau?

In the middle of the square, Dr. Mengele, an SS officer with a conductor's baton in his hand, separates the men according to who can work and who cannot. Elie and his father remain together. The new arrivals are taken to the showers, shaven at the barber, and given work clothes. As the Jews assemble into crowds, some are joyful at being alive, others cry. Elie notices that both he and his father have changed during the grueling process of being turned into prisoners of camp.
