History of Medicine Questions

I need help with a History question. All explanations and answers will be used to help me learn.

Hi. These are the questions that I need answers for. All of the questions should be answered using the sources provided. Thanks!

1. According to Lock and Kaufert, in their study, what are the variables taken into consideration when defining “menopause”? What do they mean by “local biologies”? What are the differences in understanding menopause between Japanese (Chinese, Thai) and North American (the US, Canada) societies?
2. Do you consider Cobb’s article a primary or secondary source for understanding the Tuskegee syphilis study? Why? According to the author, what made the study possible and what terminated the study? What did the study add to the medical knowledge of syphilis?
3. In “Materials on the Trial of Former Servicemen of the Japanese Army,” what were the crimes committed by these servicemen of the Japanese army? What are the similarities and differences of the implemented human experimentations between Japanese army and the Tuskegee syphilis study?
