I think there are two ptions that show internal conflict:
1) He considers whether or not to trust the inmate who tells him he´s not fifteen.
In this case he doesn't know the inmmate and doesn't know the exact reason hes telling him to lie. One reason is because he wants to help him, that information would save his life from the SS. The other option is that the inmmate is selfish and by telling him to lie, the kid will be punished instead of him. The kid must decide then if he trusts him or not.
2) He must decide whether or not to tell Dr. Mengele the truth about his age.
In this case he has even more doubts, he knows Mengeles reputation and he doesn't know how much information does he have and how will it affect him. If he lies he might know it and punish him or that lie could save him.
The conflict is real because his life could depend on the decissions he makes.
The author uses people to describe the scene.
Differences in strength, hormones, body structure, bone structure. Like when you draw a man figure, the body is usually a rectangle but when you draw a female, the body is an upside down triangle. Hormones like estrogen, only women have. Similarities are intelligence, appearance. Women and Men are treated differently, especially in the work place, because they used to be seen as lower class and we are thought of not being able to do some of the obs that men do, like manual labor because women don't have the same muscle mass or upper body strength as men do but men are also seen as not being able to do some jobs that women do, especially in households, because they don't have motherly instincts or they can't cook as well as women can.
