1. To a prisoner that was forced to work in the death camp, anything that didn't involve dead bodies and the smell of burning flesh would seem like a miracle. Buna was a rubber factory so they did not have to throw the bodies of their friends and family in the fire. Even throwing someone you did not know into a fire would be terrible. Knowing that you are condemned and helping that fact along would be a terrible feeling. Birkenau was a death camp so the people there were used to help the killing along only to be murdered later. At Buna the workers were healthier than those waiting to die at Birkenau so it was easier to keep their faith and hope alive. There was less of a cloud of misery over their heads because they had come face to face with death and seen what could have been, then they got to go somewhere else. They were almost grateful and happy to be there.
2. The French girl wanted to be sent to the concentration camp where she would be forced to work because by working and pretending not to be Jewish, she would have a chance to live. If the Nazis would have found her and found out she was a Jew, they would have killed her on the spot. By being deported to Buna and pretending not to speak German, she preserved the identity she had, one as an Aryan. She was just hoping to make it through alive.
3. From our measurements (which may be a little off so just go with it-don't attack us over it) the distance between Birkenau and Buna was about 6 miles. The march may have taken so long because there were so many people and it was freezing cold outside and people were dying all around them. They went through villages and there were so many subcamps around to go through. It took so long because of the magnitude of the group and the places they had to go through to get to Buna. If there were wide open spaces that everyone could just walk freely toward the camp they could have gotten there in an hour, but they had to condense the lines and walk after each other.
